Considering the toxicity potential of pesticides and the expansion of agricultural frontiers in
the country that consumes the most pesticides in the world, this study aims to evaluate the
environmental exposure to pesticides at the time of their intensive use in human individuals
from communities on the agricultural frontier of PA -370, Santarém-PA, in the Eastern
Amazon. This is an analytical epidemiological study of an ecological character, carried out
using a socio-demographic questionnaire and chemical risk perception, unstructured interview
and evaluation of the plasma cholinesterase enzyme (BuChE), in the prospective communities
Urumanduba, Henrique Mendes, Planalto Fé em Deus, Volta Grande, São Jorge, Boa
Espeança and Tipizal. Through the obtained data, the profile of the residents was described
through education, main activity and perception of chemical risk, besides accounting for
reports of clinical manifestations related to exposure to pesticides and, among the most
frequent clinical manifestations, were described the headache, eye irritation, dyspnoea and
cough. It was also found that the chemical compound most frequently used at the time of the
research was the glyphosate isopropylamine salt (Roundup®). Regarding the evaluation of
BuChE, there were no significant values of alteration compared to the reference values,
because there was no use of anticholinesterase pesticides at the time of the study. Afterwards,
we analyzed the landscape of the communities from charts obtained by Google Maps® and,
from this analysis of the around landscape, we conclude that the larger the extensive
production of around, the greater the quantitative of the reports of occurrence of clinical
manifestations related to poisoning by pesticides which, based on other observations, leads to
the importance of more research directed to both public health and the environmental area, in
communities that have extensive productions in their around.
