0251/2018 - Estimativa de contaminação de águas subterrâneas e superficiais por agrotóxicos em área sucroalcooleira, Santa Rita/PB. Estimate of the contamination of groundwater and surface water by agrochemicals in the sugar and alcohol area, Santa Rita/ PB.
O aumento da produtividade agrícola, em especial a produção canavieira geralmente está associado ao uso de agrotóxicos. O risco de contaminação desses compostos nos recursos hídricos é uma preocupação para a saúde pública e ambiental. Nesse contexto, o estudo objetivou estimar o potencial de contaminação das águas subterrâneas e superficiais por agrotóxicos aplicados em uma área sucroalcooleira na região metropolitana de João Pessoa, município de Santa Rita/Paraíba. A análise foi realizada seguindo critérios propostos pela Environmental Protection Agency - EPA e índice de GUS (águas subterrâneas) e pelo método de GOSS (águas superficiais). Como resultados da estimativa de contaminação das águas subterrâneas, observou-se que dos 25 princípios ativos avaliados pelos métodos (EPA e GUS), 52% apresentaram tendência de contaminação potencial. Quanto ao risco de contaminação das águas superficiais, a maioria dos princípios ativos possuía uma maior tendência de transporte de suas moléculas dissolvidas em água e transportadas por meio do carreamento das águas da chuva. Assim, pode-se concluir que há a necessidade de implantação de programas de monitoramento ambiental e de medidas voltadas à proteção da saúde pública.

Abstract:
The increase in agricultural productivity, especially sugarcane production, is generally associated with the use of agrochemicals. The risk of contamination of these compounds in water resources is a concern to the public and environmental health. In this context, the aim of this study was to estimate the contamination potential of the groundwater and surface water by agrochemicals applied in a sugar and alcohol area in the metropolitan region of João Pessoa, Santa Rita/Paraíba. Analysis was performed according to the criteria proposed by the Environmental Protection Agency - EPA and GUS index (groundwater) and by the GOSS (surface water) method. As a result of the estimation of groundwater contamination, it was observed that 52% out of 25 active principles evaluated by the methods (EPA and GUS), showed a tendency of potential contamination. About the contamination of surface waters, most of the active principles had a greater tendency to transport their molecules dissolved in water and transported them through the rainwater. Thus, it can be concluded that there is a need for the implementation of environmental monitoring programs and measures aimed at the protection of public health.
