The choice of this study had the general objective of verifying the presence of pesticides (Glyphosate
and AMPA), from soybean cultivation, in the waters of Ribeirão Taquaruçu, in the municipality of
Palmas and possible interactions with exogenous intoxications in the Metropolitan Region of the
capital of Tocantins. In order to fulfill the proposed objectives, a planning was carried out in the
first phase in order to determine the collection points, as well as the appropriate handling and
transport of the collected samples to obtain the necessary information. In the second, the frequency
of notifications of exogenous intoxication by pesticides in the Metropolitan Region of Palmas - TO,
in the period from 2010 to 2020 was analyzed. The results revealed that the tolerance limits
compared to CONAMA Resolution 357/2005 - Quality Standards of Fresh Water for Supplying
Human Consumption were not surpassed in any of the analyzed criteria. Therefore, the waters of
the Taquaruçu basin do not have restrictions for human consumption, regarding glyphosate
contamination. The notifications of exogenous intoxication by pesticides in the municipalities of
Tocantins, showed that the city of Palmas, in the period of 9 years, was considered the 2nd in the
ranking, with 107 cases, 76 men and 31 women. Based on the results found, the need to improve
the unified system of records of poisonings is evident, both in measuring and in better handling of
data, so that they could be associated with a public health policy. In this way, expanding the
instruments of public policies in order to provide guidance on the use of toxic substances,
contributing to the reduction of the number of notifications due to intoxication.
