0. EXECUTIVE SUMMARY
The constant concern
about the hazards of spraying the herbicide glyphosate and its effects
on Ecuador's border territory has brought together various organizations
to conduct a verification mission aimed at determining how it has affected
the population in Colombia and Ecuador living alongside the San Miguel
River, in the sectors of Aguas Blancas, La Pedregosa, Nueva Granada, and
Los Cristales, in Colombia, and Chone 2 and Puerto Nuevo, in Ecuador (see
map). The results of this verification are as follows:
- The new fumigation
period to eliminate illicit crops that started on July 28 in the Department
of Putumayo, in Colombia, and on the border zone, in Ecuador, has triggered
severe impacts on the population's health and on crops, animals, and
ways of living.
- The work done
by the multidisciplinary and inter-institutional team in the border
zone and the calculation of distances with GPS from the points where
there were fumigations up to the San Miguel River have made it possible
to corroborate that no attention has been paid to the requests made
by Ecuador's Ministry of Foreign Affairs or by the Ecuadorian Ambassador
to Colombia, regarding the establishment of a buffer zone for the fumigations,
preventing fumigation within a perimeter of 8 to 10 km from the San
Miguel River (binational limit) inside Colombian territory.
- Regarding this,
it was confirmed that fumigations are affecting Ecuadorian territory.
In some cases, spraying extends up to the bank of the San Miguel River,
and planes are infringing upon Ecuador's air space. In addition, because
of the air currents chemicals drift into Ecuador and severely damage
the way of life of Ecuador's border population.
- Medical tests
have established a relationship between the symptomatology described
by the population and that stemming from the inactivation of cholinesterase,
which is the effect coming from organophosphates. The central nervous
system is overstimulated, which causes the following: headache, dizziness,
nausea, vomiting, stomachache, and weakness. To these symptoms must
be added others that are specific to Roundup Ultra, characterized by
intense eye and skin irritation.
- Blood samples
drawn from inhabitants of the border zone call attention to the risk
involved in fumigating a population that has chromosome fragility levels
that are 17 times higher than normal. This situation poses questions
about the incidence of recent fumigation in increasing chromosome aberrations
that have been detected or, if they are due to other factors that have
not as yet been determined, about the negative influence on a population
that is already at risk. This situation is extremely sensitive, because
chromosome vulnerability implies that cancer, mutations, malformations,
and abortions may appear more easily.
- Inhabitants of
the area reported having seen two different types of fumigations (one
involving a whitish liquid and the other brown dust), and this has led
us to analyze plant samples to discount the possibility that the biological
agent Fusarium oxysporum is being used despite prohibitions currently
in force. Should this be the case, it would mean that biological agents
identified as biological weapons were being used, which would evidently
have severe international implications. Although constraints for the
technical analysis for detection prevented us from determining the species,
the genus Fusarium was found in all of the samples that were
taken, whether roots, leaves, or soil.
- The damage to
both subsistence and cash crops, whether entire crops or a very large
share of them, has affected this region's population, bringing it to
the brink of a food crisis and forced displacement. These peoples are
not receiving any health support or compensations to offset their losses.
1. BACKGROUND
Aerial fumigations,
as part of the Plan Colombia, officially started in the Department of
Putumayo on December 22, 2000. By January 28, 2001, about 29,000 hectares
had been fumigation; during 2001, according to the U.S. Embassy in Colombia,
94,000 hectares were fumigated. The U.S. Administration is planning to
expand the fumigation area to 150,000 hectares during 2002 and to 200,000
hectares during 2003, which will heighten socio-environmental and health
impacts on the people in the border area.
1.a The chemical formula
used
Although it has been
impossible to confirm the chemical mix that is being sprayed, according
to the technical parameters of the National Narcotic Drugs Council for
the aerial fumigation of illicit crops, [1] the following amounts are being
applied in the mix:
Plan load
|
300 – 450 gallons
|
1137 – 1705
liters
|
Effective unloading
(of Roundup Ultra, with 43.9% of glyphosate)
|
23.4 liters/hectare
(30 tp 50 drops/cm2)
|
10.3 L/ha of
glyphosate
|
Deposit of
mix
|
0.4 – 0.7 mm3/cm2
|
40 – 70 liters/ha
|
The
mix used contains: 44% of Roundup Ultra, whereas the label for use in
the United States for Roundup Ultra permits concentrations of between
1.6% and 7.7% for the majority of uses and a maximum concentration of
29%. The U.S. label indicates that, under most conditions, the aerial
application should not be over 1 liter (quart) per acre of the formulated
product. In Colombia, the rate is equivalent to almost 4.5 times this
amount. [2]
If it is estimated
that a 300-gallon plane (1,137 liters) drops 40 L/ha of mix, with an effective
drop of 23.4 L/ha of Roundup Ultra; this drop is equivalent to 10.3 L/ha
of glyphosate in the form of IPA salts. This means that the glyphosate
is applied in concentrations of 26%, not at the 1% rate recommended in
the United States for land applications, with protection gear and aimed
at farm weeds. To this situation must be added the fact that Cosmo Flux
411F multiplies the biological action of glyphosate fourfold.
1.b Impacts of fumigations
in Colombia in 2001
The fumigations in
Colombia have sparked a major debate, in view of the many reports of damage
to licit crops and especially to the health of the population living in
the areas adjacent to the areas of fumigation.
In the Municipality
of Valle del Guamuez, which lies on the Ecuadorian border, a consolidated
report on the impacts stemming from fumigations was issued: 1,551 persons
had their health affected, 3,174 hectares of licit crops were destroyed,
and 55,045 animals were affected or died, distributed across 44 precincts.
This report, prepared
by the Police Station, [3] focuses on damage to crops and
animals, broken down as follows:

1.c Impacts on Ecuador
of the fumigations in Colombia in 2001
In October 2000,
the press reported the first impacts on health in Mataje (Esmeraldas)
associated to the fumigations in the Department of Nariño, with 44 persons
falling sick after the first fumigation (El Comercio, Quito, October
22, 2000).
In January, El
Comercio reported on the impacts in the province of Sucumbíos stemming
from fumigations in December (El Comercio, Quito, January 12, 2001).
Months later, 188
campesinos from different communities filed a report with the Office of
the Human Rights Ombudsman in Lago Agrio, which was transferred to the
Ombudsman in Quito, where its processing came to a standstill. The report
set forth the claims of the campesinos of the parishes of General Farfán,
Nueva Loja, Pacayacu, Dureno, and Tarapoa. The claim noted the following

Despite huge loses
for subsistence and household farming, no government official has traveled
to the areas to check, in the field, the damage reported in this claim.
1.d Impacts of fumigations
in Colombia in 2002
The second phase
of fumigations started on July 28, 2002. Despite the short time that
has elapsed, reports are piling up in the following institutions:
-
The Municipality of Puerto Asís [4] reported that, since August 11, 2002, it has been fumigated,
and this has “affected more than 2,254 families (from 58 precincts), some
of whom are beneficiaries of the Manual Eradication Program."
-
A report from Agroamazonía [5] dated September 23, 2002 describes how palm heart plantations
have been affected in the Valle del Guamuez, Puerto Asís, and Orito. Out
of 32 palm heart growers covering 54.8 hectares of sown crops, damage
has been reported in 43.8 hectares, which accounts for 80% of farmed area.
-
The Office of the Human Rights Ombudsman for the Colombian People [6] asserted the following on October
9: “3.9.5 In addition to the previous reports, in the department there
have been complaints about harm to the health of the inhabitants, presumably
caused by fumigations. The report of the Deputy Department of Public
Health of the Department of Putumayo on the impacts of fumigations in
various municipalities of this territorial institution informed that “(…)
4,883 (85%) of the 5,929 persons referred to in the complaint forms and
interrogated by the officials of the Technical Assistance Unit of Orito
and coming from 46.4% of the 282 precincts comprising the three municipalities,
spoke about symptoms that can be attributed to the fumigation. The symptoms
were associated to respiratory problems 29% (964), gastrointestinal problems
26.4% (876), skin problems 15.8% (524), psychological problems 1.9% (64),
fever 15.5% (516), general indisposition 5.4% (179), dizziness 4.1% (32)
and others 0.9% (29)”. This report adds that, in the Hospital de la Hormiga,
there was “a statistically significant rise in episodes of fever, diarrhea,
abdominal pain, acute respiratory infections, and skin infections.” The
report concludes: “An epidemiological surveillance system for acute intoxication
caused by pesticides and a nutritional surveillance system are required.” [7]
1.e Impacts on Ecuador
of fumigations in Colombia 2002
The “Santa Marianita”
Association of Campesinos [8] of the Parish of General Farfán,
comprised of 27 members, reported that after the recent fumigations in
Colombia they have suffered from “skin and eye diseases, respiratory infections,
fevers like those resulting from malaria, but tests turn out to be negative.
Females animals have problems when giving birth and we have noted a fall
in the production of corn, cacao, rice, bananas, to such an extent that
we cannot get our investment back.”
The Chone 2, Puerto
Nuevo and La Playera communities on the Tetetes road, in the parishes
of Pacayacu, reported damage to their crops and animals. Likewise, they
spoke of severe damage and health problems in the border community of
Cohembí.
1.f Government actions
On July 2, 2001,
the Ecuadorian Government requested the Colombian Government:
-
“that the applications of chemical formulas used on its territory take
place at least 10 kilometers away from the Ecuadorian border, so
as to prevent the dispersion caused by winds from reaching Ecuadorian
territory and producing toxic effects on persons and plant life.”
[9]
The Ministry of Foreign
Affairs of Colombia replied to this request
[10] on July 14, 2001 and stated:
-
The Colombian Government has adopted the necessary precautions in programming
its fumigations. In its substantive part, it proposed holding a Seminar-Workshop
in Colombia, where the Government of this country “would have the opportunity
to provide all the technical information required by Ecuadorian officials,
for the purpose of addressing all existing concerns and building up a
spirit of binational cooperation." During the Seminar-Workshop
on the Eradication of Illicit Crops held in Bogotá, Colombia on February
13-15, 2002, the Colombian delegation pledged "to ensure an 8 to
10-kilometer buffer zone without any chemical spraying from the San Miguel
River, which is the binational border limit, inside Colombian territory.”
2. OBJECTIVES
OF THE VISIT AND PROCEDURE
On the basis of this
background, a multidisciplinary inter-agency commission was established,
comprised of the Latin American Association for Human Rights (Asociación
Latinoamericana para los Derechos Humanos, ALDHU); the Network for Action
and Alternatives to Pesticides (Red para Acción y Alternativas a los Plaguicidas,
RAPALl – Ecuador); and Ecological Action (Acción Ecológica), along with
the Office of the Human Rights Ombudsman of Sucumbíos, Laboratories Labsu,
Creative Action (Acción Creativa) and some of the media.
The purpose of this
Commission was to conduct a Verification Mission to study the impacts
of fumigations on the border and corroborate reports that were received,
by doing field tests that would demonstrate the degree of vulnerability
and disease of the border population. For this purpose, the Commission
traveled to the province of Sucumbíos, in the zone of the Tetetes road,
at the end of September 2002.
The objectives of
the mission were:
1.
To determine if the distance of the fumigations observes the request made
by the Ecuadorian Government to keep a 10-kilometer safety strip inside
Colombian territory to safeguard the rights of Ecuadorians.
2.
To check the reports on the impacts of the fumigations for the health
of the inhabitants of the zone and corroborate a report on the decease
of five persons in Cohembí (Ecuador).
3.
To analyze the crops affected by the fumigations, check the alleged use
of Fusarium oxysporum, and determine soil nutrients and to what
extent they have been affected.
3. RESULTS
3.a. Objective
1: Determine if the distance of the fumigations observes the request made
by the Ecuadorian Government to keep a 10-kilometer safety strip inside
Colombian territory to safeguard the rights of Ecuadorians.
The Seminar-Workshop
on the Eradication of Illicit Crops that was offered by the Colombian
Government took place in Bogotá, Colombia on February 13-15, 2002, in
order to “illustrate its program for eradicating illicit crops and
providing all the technical information that government officials might
need.”
The Seminar was attended
by “high-level political, rather than technical, authorities, responsible
for drug policymaking in Colombia, (…) the Ecuadorian delegation questioned
the absence of technicians from the corresponding ministries (Agriculture
and Livestock, Health and Environment) and (…) the informative lectures
were delivered to an audience comprised largely of policemen, fumigation
pilots and politicians.” [11]
Despite these constraints
and the absence of official analysis and information at this event that
would have enabled the Ecuadorian Government to take preventive, remedial,
and precautionary measures for future fumigations and to establish emergency
programs for the border population, the Seminar was able to draw at least
three important, decisive conclusions, in line with what was requested
by the Ecuadorian Government through its Ministry of Foreign Affairs:
a)
A 8 to 10 kilometer safety strip away from the binational border
toward the interior of Colombian territory will not be fumigated (in this
buffer zone manual eradication programs will be used).
b)
Research on the impacts on water, soil, flora and fauna in shared
ecosystems needs to be conducted.
c)
The program for eradicating illicit crops does not have an Epidemiological
Surveillance System.
At this event, the
Ecuadorian Ambassador to Colombia, Fernando Ribadeneira, reiterated Ecuador's
request regarding the “advisability of fumigating, as long as a safety
strip of up to 10 kilometers away from the border is observed so as to
safeguard the population and territory of Ecuadorian from the possible
damaging effects of this spraying.”
[12]
The commitment to
respect the 8-10 km buffer zone in the fumigation program was clearly
stated by four of the lecturers representing the Colombian Government:
“We have not fumigated
up to a margin of at least 7 kilometers away from the Ecuadorian border.”
[13] Dr. Richard Baca, Director of the Anti-Narcotics Agency
(NAS) of the U.S. Embassy in Colombia.
“A strip of 8
to 10 kilometers away from Ecuador is no longer being fumigated.”
[14] Luis Parra, Advisor to the NAS in the U.S. Embassy in Colombia,
and Major Vargas, Field Visit Coordinator.
“Fumigations are
taking place at a distance of 8 to 10 kilometers away from the Ecuadorian
border.” [15] General
Gustavo Socha, Director of the Anti-Narcotics Police.
Despite the above,
the results of the verification conducted in the border zone have led
to the conclusion that this government agreement has not been observed
and Colombia continues to spray along the Ecuadorian border. Since 2001,
local reports have referred to fumigation planes violating Ecuadorian
air space so as to turn around and continue spraying. If concrete evidence
is provided to prove this, it points to a direct attack on Ecuadorian
territorial sovereignty.
To check the distance
of the fumigations made on the border, the verification mission entered
Colombian territory and, with GPS equipment, proceeded to identify the
zones fumigated in Colombia and their distance from the San Miguel River.
It obtained the following results:

-
In Pedrera (point 7), six meters from the San Miguel River, signs of crops
destroyed by fumigation, possibly from wind drifts, were found.
-
At point 10, severe impacts were observed, since the area was sprayed
directly at 706 meters away from the border.
-
In the precinct of Nueva Granada (points 8 and 9), at 1,600 meters from
the border, eye-witness accounts by the population reported that, between
August 30 and September 6, planes fumigated directly onto their houses.
As proof of this, on the football field, located in the middle of the
town, there were large rings of chlorosis. The schoolteacher stated that
her 35 students fell ill with headaches, sore and runny eyes, and fever.
-
In Aguas Blancas (points 15 and 16), at a distance of 7 to 8 km from the
border, there were clear signs that all kinds of crops had been destroyed.
-
In Los Cristales (point 14), there were eye-witness accounts of airplanes
flying over the houses and spraying them on August 1 and 18, 2002, without
any consideration for how it would be affecting homes, food crops, and
water sources.

In La Playera Oriental and Chone 2 (between 1 and 1,257 m from the bank
of the San Miguel River, evident damage from the fumigation of September
6, 2002 on the Colombian side of the banks of the San Miguel River was
observed. At all points, soil and plant samples were taken, health data
on the population were gathered, and eye-witness accounts on social impacts
were recorded.
-
In front of La Pedregosa (point 12, at 186 m inside Ecuadorian territory)
damage was found in the banana plantations and other crops, which showed
signs of chlorosis (yellowing), as a result of the proximity of fumigations
in Colombia. The accounts pointed out that these impacts stemmed from
the fumigations done on the Colombian side between August 30 and September
6, 2002.
What was observed
by the verification mission, the results from the samples that were taken,
the eye-witness accounts that were recorded, and the interviews that were
conducted enable us to assert that the fumigations in Colombia are taking
place less than 10 kilometers away from the Ecuadorian border. On the
basis of the above, it can be concluded that, at the time of the mission,
the request made by the Ministry of Foreign Affairs and the Ecuadorian
Ambassador to Colombia had not been met.
In some cases, there
were fumigations as close as the banks of the San Miguel River. The drifting
of sprayed products has caused severe harm to the Ecuadorian border population.
3.b Objective
2: Check the reports of impacts of fumigations on the health of the inhabitants
of the zone and corroborate a report on the death of five persons in Cohembí
(Ecuador).
In June 2001, Ecological
Action published a Research Report [16] on the impacts of fumigations
of January 2001 on the border of Sucumbíos. The report showed that:
-
100% of the population living in the border zone had been intoxicated
by the Roundup Ultra fumigations over a 5 km strip, and 89% of the population,
if the strip is extended to 10 km.
-
Three months after the fumigations, the population up to 5 km kept showing
symptoms of chronic intoxication with signs of neurological impairment,
skin problems and conjunctivitis.
-
There is a direct linkage, in terms of time, between fumigations and the
appearance of disease.
-
There is a direct linkage between the distance of site that was fumigated
and symptomatology. The symptomatology in the population declines in
proportion to the distance of the fumigated site.
-
The possibility of new fumigations on the population that is already suffering
from symptoms of chronic intoxication may cause an impact of incalculable
consequences for their lives.
-
The population, which has suffered from the impacts of the fumigation,
has become frantic. They do not benefit from any economic support, compensation,
or suitable care for their health, which has been undermined by a fumigation
program that renders them invisible.
-
The negative impacts on the population's health and its nutritional status
may increase if no adequate measures are taken to offset the failure of
their crops and the death of their livestock and barnyard animals.
-
The permanence of Roundup in the soil (from 120 days to 3 years) has generated
considerable uncertainty among the population regarding the future of
their crops.
Because of prevailing
winds at that time of year, communities such as San Francisco 1 and 2,
Nuevo Mundo, San Miguel, 10 de Agosto, Proyecto San Miguel, and Perla
del Pacífico, among others, were severely affected. Today, on the Tetetes
road, most of these conclusions also hold true.
The report also recorded
the death of four children during the first days of fumigation. Reports
from the Colombian Red Cross, the Hospital del Sagrado Corazón de Jesús,
Valle del Guamuez, the Municipal Police Station (from the same station),
health solidarity companies (empresas solidarias de salud, ESS), the Office
of the Human Rights Ombudsman,… include documents and clinical histories
referring to persons who were affected by the fumigations.
Regarding the reports
about the death of five persons in the community of Cohembí, it was not
possible to corroborate whether these deaths were caused or motivated
by the fumigations. Logistic and security constraints have prevented
access to this community.
Because of this situation,
the verification mission traveled to a zone that was also affected by
the fumigations, but enjoyed better access conditions. For this inspection,
the Commission undertook two health studies: a comparative study of the
impacts of fumigation on the health of the population of both Ecuador
and Colombia; and a study based on blood tests to identify potential chromosome
alterations.
3.b.1 FIRST STUDY:
Clinical histories
Out of a universe
of 199 families, 33 families were surveyed (16.6% of total), distributed
among six communities, two in Colombia and four in Ecuador, with a total
population of 657 persons in Ecuador and 470 in Colombia.

The average of affected
persons among both populations is 88.5% in Colombia compared to 80% in
Ecuador. The comparative table of symptoms between one population and
the other can be appreciated in the chart on the “Impacts of fumigations
on health in Ecuador and Colombia”.
From the clinical
histories that were examined, we can infer the following:
-
A large majority of the population after the fumigations has felt adverse
impacts such as headaches and eye irritation and tearfulness. In the
Colombian communities that were more intensely fumigated, it was common
to find digestive problems, with dizziness, abdominal pains, vomiting
and nausea, diarrhea, fatigue and loss of energy. This symptomatology
is typical of organophosphates, which is the group that Roundup Ultra
belongs to. The presence of fever in Colombia is also significantly more
widespread than in Ecuador.
-
Another group of symptoms appears because of skin diseases. A great deal
of pruritus (itchiness) is associated to different diseases, ranging from
dermatitis (inflammation) to the appearance of pimples for different reasons.
The irritation caused by the chemical is evident in this symptomatology,
which also occurs in the eyes, which has a higher incidence on the Ecuadorian
side than the digestive symptoms.
-
Some campesinos indicated that there are two types of fumigations: one
involving a whitish or transparent fluid and the other a dark color, after
which there is a powerful "itch."
-
The psychological impact that the fumigations exert on the campesinos
of Ecuador is different from that on Colombia. Whereas the former display
stress which leads to insomnia, the Colombians are depressive as a result
of the complex reality that the inhabitants of this zone have to live
through, heightened by the impacts of fumigations.
The symptomatology
described by the population is consistent with what is produced as a result
of the inactivation of cholinesterase, which is the impact of the organophosphates.
The central nervous system is overstimulated, which in turn causes: headaches,
dizziness, nausea, vomiting, stomachaches, and fatigue. This symptomatology
is accompanied by the specific components of this product, which produces
acute eye and skin irritation.
3.b.2 SECOND STUDY:
Blood test results
One of the principal
arguments of those who are for eliminating illicit crops by using pesticides
is the claim that Roundup Ultra is harmless.
[17] Nevertheless, it is well known that the active ingredients
used in elaborating pesticides for commercial use exert adverse effects
on health, not only for the end-consumers of the foods that are treated
but also for the workers who have been exposed to them.
[18] Among the effects caused by pesticides, the most important is
genotoxicity, defined as the facility of producing alterations in the
genetic material and therefore, the propensity for cancer, mutations,
and alterations of the embryo.
The blood tests that
were taken were aimed at determining if the population affected by the
fumigations showed any significant alterations in their chromosomes.
To do this the following was used: a) “comet assay” and b) cytogenetic
analysis, to look for chromosome aberrations (CA). Both tests are different,
but complementary and have proven to be adequate biomarkers for chromosome
fragility.
“Biomonitoring
studies in human populations show that an increase in CA frequency is
related to exposure to genotoxic agents, and it is know that there is
an association between the frequency of CA and the risk of developing
cancer. Duplication in the incidence of cancer in individuals with a
high frequency of CA has been reported, therefore the analysis of CA can
be used to estimate the risk of cancer and genetic diseases.”
[19]
At first, it was
expected that eight samples would be taken, because this is the laboratory's
maximum capacity for analysis. Unfortunately, persons on the Colombian
side did not arrive on time for the sample taking and so, for this first
study, we only had four samples from Ecuadorian persons. Despite the
low representativity of the samples that were taken, the results obtain
have encouraged us to publish this report and to propose undertaking more
extensive and systematic analyses of the impacts on the health of the
population in the border zone affected by fumigations.
Bearing in mind that
fumigations have increased in the Department of Putumayo and that there
have been fumigations once again in the area where the samples were taken
(October 4, 2002), we believe that it is urgent to analyze and determine
the scope of the risk that the population located on the border is running.
Procedure.
Four persons were evaluated: three women and one man, with an average
age of 39 years old (women of 37, 40 and 53 years of age; 27-year-old
man). The women received the impact of the fumigations at a distance
of 200 meters; whereas the man's body was sprayed with fluid while he
was working. All were exposed on the same dates and during a period of
about one week. The samples were taken two weeks after the exposure.
One of the women had traveled to Lago Agrio a week earlier because of
the symptomatology secondary to the fumigations. None of them smoke,
nor do they have any other contact with chemicals or other genotoxic elements.
The tests were examined
at the Laboratory of Molecular Genetics and Human Cytogenetics of the
Pontifical Catholic University of Ecuador (PUCE) and they consisted of:
Comet assay:
It is a test that
is very sensitive to changes or alterations in one or two of the DNA cell
chains on which genotoxic agents have acted. It has the advantage of
being rapid in obtaining results. This test was developed by Singh (1988)
and in Ecuador there are many activities for which the Laboratory of Molecular
Genetics and Human Cytogenetics of PUCE carries out this test. At present,
it is used in clinics, human monitoring, radiation in biology, and genetic
toxicology, among others. It has been demonstrated that the test is very
sensitive for the surveillance of chemicals and complex genotoxic mixtures.
In short, the test
consists of subjecting cells to an electrical field. If there is no damage
to the cell, the genetic material remains unaltered and the nuclei of
the cells appear to be circular. The greater the damage to the genetic
material, however, the more deformed are the nuclei of the cells and the
more they look like comets trailing through space, and that is where they
get their name from; depending on the amount of damage, the tail of the
comet will be more or less dispersed (see photo and table below).

The results obtained
from this test are highly significant. The analyses support the claim
that the persons who were tested are subject to a high risk of suffering
from cancer.
RESULTS FROM THE ANALYSES OF THE COMET ASSAY
# 1-CHROMOSOME FRAGILITY: 21.4% # 2-CHROMOSOME FRAGILITY:
20.0%
# 3-CHROMOSOME FRAGILITY:
30.0% # 4-CHROMOSOME FRAGILITY: 28%
Control: CHROMOSOME FRAGILITY: 2-4%
The results highlight
the following: where there should be no more than 0.5% of damaged cells,
we have found 48.3%, in case 1; 47.6%, in case 2; 69.4%, in case 3; and
58.8%, in case 4. In other words, there is a genetic damage that is between
11 and 17 times higher than normal.
Cytogenetic
analysis:
Lymphocytes of peripheral
blood were studied and chromosomes were examined to look for structural
alterations (such as breaks) and numerical alterations (loss of chromosomes
or duplications). This analysis evaluates exposure to genotoxins and
is internationally recognized.
The results of the
cytogenetic tests are as follows: “In all the cases that were studied,
there was a sign of much lesser mitotic division than what is considered
normal. The data obtained, compared with the control group established
in the laboratory, with a range of 2-4%, highlight a statistically significant
damage in these individuals.”
[20] The percentage of chromosome fragility for each one of the samples
was 20%, 21.4%, 28%, and 30%; compared to 2 to 4%, this means that their
parameters are 10 to 15 times higher than normal parameters. Their average
chromosome fragility is 24.85%.
A study conducted
by the same laboratory in the province of Pichincha in a flower plantation
showed that the workers who were examined had an average chromosome fragility
of 18.29%, with 30 times more chromosome aberrations that the control
group. On the basis of these data, it was stated that "the cytogenetic
findings provide evidence that exposure to pesticides produces lesions
to the DNA, which increases the mutagenic and carcinogenic risks in populations
that are exposed because their occupations.”
[21]
Another study
[22] from the same laboratory analyze the chromosome aberrations
occurring among hospital workers exposed to low levels of radiation.
The average (24.8) coincides with the one appearing in the group from
the border zone. This study was able to observe that maintaining exposure
to the genotoxin over time increased chromosome aberrations and therefore
the risk of suffering from cancer.
The results of the
analyses obtained on the border are even higher than those found in the
flower plantation and it has been confirmed that the analysis of chromosome
aberrations is a reliable factor for predicting cancer and can measure
the evolution, prognosis, and treatment of cervical lesions associated
to the human papillomavirus. [23]
On the basis of these
results and bearing in mind the data from other similar studies, two hypotheses
have been suggested, although they will have to be tested by further studies.
1. Fumigations may
be the cause of these chromosome aberrations and, if so, they influence
the risk of cancer among the exposed population.
2. Another chemical
element may the cause of these chromosome aberrations in the genetic material.
In this case, the fumigations may be increasing the risk of pathologies
in a population that is already especially sensitive.
Whichever of the
two hypotheses is accepted, it is evident that both highlight the need
for further, more in-depth studies on the health impacts for the population
exposed to fumigations, to be carried out systematically and with the
participation of the respective government institutions and with the mechanisms
permitting comparisons of the results of these studies.
3.b Objective
3: Analyze the crops that are affected by the fumigations, check the alleged
use of Fusarium oxysporum and determine soil nutrients and to what
extent they have been affected
After learning about
the results of the blood tests, the words of Jeremy Bigwood, Advisor to
the Ecuadorian delegation, appearing in the report attached to the analysis,
are noteworthy: “Neither the Colombian Government nor the U.S. Government
have investigated the environmental effects of various formulas that they
have been using on different ecosystems in Colombia. Such a massive use
of herbicide formulas that have not been researched and the continuous
substitution of one formula for another would never be allowed either
in the United States or in the majority of the countries of the world.
As a result of this massive use of a formula that has not been used and
the absence of research, Ecuador could well be facing a danger of unknown
proportions.” [24]
The uncertainty regarding
the chemical formula used in the program for the eradication of illicit
crops, the absence of rigorous proof about the dosage used and the levels
of concentration of the mixture, the lack of mechanisms to control them,
the frequent contradictions by authorities responsible for this topic,
and the silence of many of them are in sharp contrast to reports made
by the population on the possibility of alternating fumigations (whitish
fluid and others consisting of brown dust, after which there is severe
itching). Faced with this situation the question that is being asked
is: Is the chemical formula Roundup Ultra being used alternately with
the pathogenic agent Fusarium oxysporum?
Because of the severity
of the reports, in Ecuador and Colombia, samples were taken from the soil
and plants to discount or confirm the presence of Fusarium oxysporum
in Ecuador's territory. The samples were sent for analysis to the Ecuadorian
Agricultural and Livestock Sanitation Service (SESA), at its Phytopathology
Laboratory on the Experimental Farm of Tumbaco, which is an agency attached
to the Ministry of Agriculture and Livestock.
During the visit
in Ecuador and Colombia, samples were taken from the grass, corn, peanuts,
rice, and the soil. A selection of samples was submitted to the laboratory
for analysis, and they yielded the following results:

This first analysis
did not yield conclusive results, because it only determined the genus.
Nevertheless, the presence of the Fusarium fungus in all the samples,
not only on roots, which is its natural habitat, but also on leaves is
noteworthy.
To broaden the study,
a second step will be taken, consisting of sending these samples to laboratories
outside the country to determine if the fungus involves the oxysporum
species, that is, if it is Fusarium oxysporum and whether it has
undergone some genetic alteration or not. It is important to reiterate
that the presence of Fusarium oxysporum has severe international
and national implications because it is a biological agent used as a biological
weapon.
The presence of this
fungus could also be a consequence of the fumigations of glyphosate.
In his report, Bigwood [25]
considers that: “glyphosate increases the growth of pathogenic fungi
according to numerous scientific investigations. These fungi predominate
in an area in order to release their own toxins, which are toxic for many
of the other nearby forms of life, including mammals. One of the genera
that tend to increase in the presence of glyphosate is the genus Fusarium.
(…) Species of this genus have been responsible throughout the world for
severe damage to many crops, poisoned soil, birth defects in human beings
and, in one documented case, the death of thousands of persons caused
by their mycotoxins when contaminated cereals were eaten during the last
years of the Second World War." Maybe this can explain their widespread
presence, but it does not answer all of our questions.
As for the farm losses
sustained by the campesino sector, it was observed that on the Colombian
territory that was visited, 100% of the banana, grass, yucca (manioc),
fruit, corn, and sugarcane crops were lost. The damage and loss of animals
amounted to: hens (10%), horses (50%), cattle (46%), and dogs (16%).
In Ecuador, the differences
were significant depending on the distance from the San Miguel River,
but in both communities that were studied, major and severe damage among
the campesino families was apparent.

This situation was
prior to a second fumigation (October 4) that occurred after our visit
and will be exerting new impacts on the crops. The loss of animals was
not observed on this side of the border on this occasion.
Analysis of
plant nutrients:
The analyses of plant
nutrients by Labsu [26] (Soil, Water, and Plant Laboratory
in the city of Coca) have yielded the following results:
“Protein levels are
highly deficient (…) the plant does not absorb this nutrient because of
a possible external influence, which was clearly seen during the extraction
of material for the study. This plant was seen to be dry in its exposed
parts and with rot at the level of the roots and stems.
The Dallis grass
shows high levels of total phosphorus (glyphosate is an organophosphate) [27] , almost twice what is reported as normal in the literature
(760 mg/kg). We deem that this information indicates an ABNORMAL situation,
which means that the plant has not absorbed this excess from the soil
because the soil where this material was extracted from shows adequate,
not excessive, amounts of this element. This excess could possibly come
from an external influence that was directly applied to the leaves of
the plant. ” [28]
It is clear that
the presence of excess phosphorus is being caused by fumigation, and the
data reveal that the amount of this element is as high as in the zones
of Colombia where fumigations were directly applied (Nueva Granada, values
of 1,136.5; 1,857.7; and 945.1), as in Chone 2, (where the result was
1,880.7 of total phosphorus).
The report concludes
that “the samples that were studied have suffered from a negative external
influence, which is reflected in the drying up and subsequent death of
the plants. We believe that this study should be done in the future to
obtain further information.”
[29]
Analysis of
soil nutrients:
The results of the
analyses, which were also conducted in LABSU, on soil nutrients did not
reveal any alteration. They conclude that “the soils that are studied
do not entail any serious problem for agricultural development, except
for some where fertilization has been undertaken. Nevertheless, constant
monitoring is considered necessary to determine the progress in the processes
of soil and crop degradation. ” [30]
In view of the above,
a new visit to the Ecuadorian zone is being planned in six months to examine
the evolution of the soil's conditions.
4. CONCLUSIONS:
1.
Contrary to statements about the lack of evidence, [31] we can hereby assert that fumigations
exert severe impacts on the ecosystems, on the means of subsistence of
the population, and on their health, not only in Colombia but also in
Ecuador.
2.
The results found in the blood tests conclude that the population
living along the border, because of alterations to their chromosomes,
is exposed to a higher risk of suffering from cancer, mutations, and congenital
deformities. Fumigations may be at the origin of chromosome aberrations
that were found or may trigger these diseases because they are acting
on a population that is already at high risk. The studies will continue.
3.
Fumigations have generated massive damage on the crops, some of
which with the help of municipalities, as well as impacts on the health
of the population and social alterations in the communities that have
been affected. The laboratory analyses show the widespread presence of
Fusarium, as a possible secondary effect of Roundup Ultra on crops
(we advise undertaking analyses to discard the possibility of other origins).
They also show that damage in Ecuador is due to the aerial drift from
the fumigations.
4.
Colombian authorities are not observing the security buffer zone
requested by the Ecuadorian Government. Not only are there fumigations
inside the 10-km protection zone that was requested, but also directly
on the banks of the San Miguel River, which is the country's northern
limit with the Colombian border.
5.
The fumigations are turning out to be ineffective in eliminating
illicit crops and are forcing the displacement of the population.
6.
It is urgent to insist on the manual eradication of illicit crops
in the border zone.
7.
Fumigations constitute a violation of social, economic, and cultural
rights of the affected population and especially undermine the rights
of the indigenous peoples of the Amazon region, in view of the close relationship
between the land and cultural survival.
8.
The impacts that were observed support the assertion that, in
the areas that were visited, there is a food crisis as a result of the
destruction of subsistence crops and the raising of animals.
9.
The absence of any monitoring of the impacts stemming from the
fumigations along the border undermines the legitimacy of the State and
jeopardizes the conditions of governance in the area, which also affects
the enforcement of human rights.
5. RECOMMENDATIONS
-
Sustained by the Constitution's precautionary principle, which in Article
91 provides that the Ecuadorian State “will take preventive measures
in case there are doubts about the impact or negative consequences of
an action or omission, although there is no scientific evidence of damage…,”
we urge the National Government to start as quickly as possible the respective
diplomatic actions and request the Colombian Government to stop fumigating
the northern border zone, because signs of severe impacts on human health
and the environment of Ecuador's border population have been found.
-
That the National Government start the investigations it deems advisable
in order to examine more in-depth the reports and investigations that
various social organizations have been submitting to it for its consideration
since July 2001, so that, on the basis of substantial evidence, a formal
complaint can be filed against the Colombian Government regarding the
possible contamination of the border zone.
-
That in turn the National Government start the corresponding investigations
to determine the presence or absence of Fusarium oxysporum on Ecuadorian
territory and that its results be disseminated nationally through regular
channels. This subject should be dealt with in the National Security
Council (COSENA), because if the presence of pathogenic biological agents
is confirmed, we would be dealing with a case of biological warfare, which
would involve filing a protest for violation of international agreements
on the restriction of the use of biological weapons.
-
That their effects be remedied and the affected population compensated,
because the hunger stemming from the loss of their crops and animals must
be relieved and offset to prevent them from being displaced and seeking
shelter elsewhere. Otherwise, the basic rights of this population would
be violated.
-
That the border zone be declared in a state of sanitary and agricultural/livestock
emergency. That the Ministries of Health and Agriculture take over the
zone to provide care directly and free of charge and an effective response
to the harm that the population is already suffering.
-
That social and psychological care plans be implemented for the population
affected by the fumigations. These plans should consider programs aimed
at having children and young people who have dropped out of school for
the lack of resources or because of disease return to school.
