Abstract
Background
Agricultural crops is directly relation to the use of pesticides, pollution the environment and people mainly from agricultural regions. The state of Mato Grosso, the indigenous land (IL) Marãiwatsédé, Xavante territory was occupied since 1950 by non-indigenous that environmental transformed by agricultural and farming until 2012. When the Xavante returns to Marãiwatsédé, denunciation of infant deaths by suspected pesticides water contamination motivated this study.
Objective
To verify the residues of pesticides in the water and to discuss a dynamic of insertion of agriculture in the Marãiwatsédé and region.
Method
It was quantified a planted area, pesticide consumption, realized chemical analysis in water and river sediment, and character environment this IL and surroundings.
Results
Annually increase planted area in the region Marãiwatsédé with increase pesticide consumption. It was detected permethrin residue in the water at concentration to 0.19 μg/L. There were crops in activity on the edge of IL.
Conclusion
The permethrin found in water was levels were lower than the limit established by Brazilian legislation but like to Europe legislation, more restrictive. However, this crops in activity the edge Marãiwatsédé are continuous emission sources of pesticides, which allows new pollutions.
