Resumo: | |||||||||||||||||||||||||||||||||||||
This study proposes to evaluate the presence of the herbicide paraquat in
runoff water in a catchment in the municipality of Bom Jardim – RJ, using two
steps: modelling and simulation with GIS (Geographical Information System).
The step of modelling was developed specifically for five standarded
Wischmeier scenarios, considering the respective crops, management, soil type
and the following parameters: culture interception and soil of the sorption. The
slope was considered only for the simulation steps of the GIS. The results were
represented as rates paraquat concentrations in runoff and afterwards validated
with real data measured in the study area and analysed by EMBRAPA SOLOS.
After validation, the scenario results was georeferenced as raster images using
the Arcgis Software 9.2, beginning the result simulation step for the watershed.
The aim is also to evaluate the influence of some parameters: paraquat
interception by the crop and slop of the catchmente. The results of paraquat
concentrations in the runoff can, in the future , be compared with accepted
standards for environmental safety, defining thereshobes limits of paraquat use
in similar watersheds. We also expect the development and application of the
same modeling approach used in this study for other types of pesticides and in
different watersheds.
