“…E, por ser inversamente proporcional, quanto maior o teor de carbono orgânico no solo, menor a concentração de tebuthiuron na água subterrânea e vice-versa. Áreas com menor teor de carbono orgânico caracterizam uma alta mobilidade da molécula do defensivo agrícola no solo, uma vez que a possibilidade de ela ser adsorvida é reduzida (Fenoll et al, 2014).…”

Resumo -O objetivo deste trabalho foi avaliar o risco de contaminação da água subterrânea por tebuthiuron, por meio da modelagem espacial, em área de cultivo de cana-de-açúcar, no Município de São Manuel, no Estado de São Paulo. Utilizou-se o modelo Araquá, para gerar estimativas pontuais da concentração, tendo-se considerado simulações no tocante às profundidades de 100 e 200 cm do lençol freático e lâminas de irrigação de 0 e 2.500 mm. Como as estimativas de concentração de tebuthiuron não apresentaram dependência espacial, os mapas temáticos de risco de contaminação de águas subterrâneas foram obtidos pelo método de interpolação pelo inverso da distância. Ao se considerar todas as simulações, conclui-se que não haveria contaminação da água subterrânea por tebuthiuron, nas duas profundidades do lençol freático, com ou sem irrigação. A interpolação das estimativas das concentrações de tebuthiuron na água subterrânea proporciona a espacialização e a rápida visualização das áreas de maior risco de contaminação.Termos para indexação: geoestatística, herbicida, lençol freático, mapas de risco, simulação. Spatial variability of groundwater contamination risk by tebuthiuron in sugarcane areaAbstract -The objective of this work was to evaluate the groundwater contamination risk by tebuthiuron in a sugarcane area, through spatial modeling, in the municipality of São Manuel, in the state of São Paulo, Brazil. The Araquá model was used to generate specific concentration estimates, considering simulations regarding different water table depths (100 and 200 cm) and irrigation depths (0 and 2,500 mm). As the estimated concentrations of tebuthiuron did not show spatial dependence, the thematic maps of risk of groundwater contamination were obtained through the method of interpolation by the inverse distance. Considering all the simulations, it can be concluded that there would be no groundwater contamination by tebuthiuron at the two depths of the water table, with or without irrigation. The interpolation of the estimated concentrations of tebuthiuron in groundwater provides the spatialization and a quick view of the areas with higher contamination risk.Index terms: geostatistics, herbicide, water table, risk maps, simulation. IntroduçãoO cultivo da cana-de-açúcar é uma das mais importantes atividades econômicas do Brasil em virtude da sua alta eficiência e competitividade, resultando em produtos como açúcar, álcool, combustíveis e até mesmo uso do bagaço para geração de energia (Silveira et al., 2014).Um dos problemas de seu cultivo, no Brasil, está relacionado com a interferência das plantas daninhas, para as quais o método empregado para o controle é a aplicação de herbicidas (Silva et al., 2015). O tebuthiuron é um herbicida residual amplamente utilizado nos canaviais, no sistema tradicional, em aplicações de pré-emergência, para controle das principais espécies anuais infestantes da cultura (Tofoli et al., 2009).No entanto, os defensivos agrícolas podem provocar efeitos prejudiciais ao meio ambiente, além de representar...

“…Fenoll et al. reported that residues from triazine herbicide had persisted in the soil for a relatively long time and could pollute surface and ground water via soil leaching . The US Environmental Protection Agency (EPA) previously reported that normal agricultural use had resulted in at least 46 pesticides entering the groundwater and 76 pesticides entering surface water bodies .…”

A sensitive and effective method for the simultaneous determination of residues from a new fungicide, oxathiapiprolin, and its metabolites (IN-E8S72 and IN-WR791) in soil, water, and sediment, was developed using ultra high performance liquid chromatography with tandem mass spectrometry. Three compounds were extracted from water, soil, and sediment by using acetonitrile and different proportions of formic acid aqueous solution (1% v/v for water; 2% v/v for soil; and sediment), and were cleaned with octadecylsilane. The target compounds were determined within 5 min using an electrospray ionization source in the positive mode for oxathiapiprolin and in the negative mode for the two metabolites. The limits of quantification for all the three compounds were 0.1 μg/kg in water and 1 μg/kg in soil and sediment. Recovery studies were performed using three spiked levels (0.1, 1, and 10 μg/kg for water; 1, 10, and 50 μg/kg for soil and sediment). The overall average recoveries ranged from 64.8 to 112.7% with all intra- and interday relative standard deviation values below 19.4 and 19.1%, respectively. The method validation confirmed that the proposed method was convenient and reliable for determining residual oxathiapiprolin and its metabolites in soil, water, and sediments.
