Pesticide Levels in Ground and Surface Waters of Primavera do Leste Region, Mato Grosso, Brazil

Abstract: Residues of the herbicides simazine, metribuzin, metolachlor, trifluralin, atrazine, and two metabolites of atrazine, deisopropylatrazine (DIA) and deethylatrazine (DEA), are surveyed in the surface and groundwater of the Primavera do Leste region, Mato Grosso, Brazil during September and December 1998 and April 1999. Different water source sampling stations of groundwater (irrigation water well, drinking water well, and water hole) and surface water (dam and river) are set up based on agricultural land use.

“…The pesticides metolachlor and endosulfan are frequently used in agriculture in the Mato Grosso State, particularly in cotton plantation and their detection in the bottom sediment can be a consequence of runoff as they were also found in runoff sediment allied to the reduced presence of natural vegetation. The detection of metolachlor over the whole period of study indicates persistent pollution, as observed by Carabia-Martínez et al 56 in Spain and Dores et al 22 in this same state in a region near to our study region.…”

“…So, based on previous studies 21,22 pesticides atrazine, metolachlor, flutriafol, α-and β-endosulfan and the metabolites endosulfan sulfate, desethylatrazine (DEA) and desisopropylatrazine (DIA) were selected for analysis (Table 1). They were selected considering the frequency of use on crops usually planted in this region of the Mato Grosso State (soy bean, corn and cotton).…”

“…Os estudos realizados em amostras de águas subterrâneas estão concentrados no Estado do Mato Grosso, [56][57][58][59][60]73 . A atrazina e o aloclor foram os pesticidas mais frequentemente dectados dentre os 27 que foram monitoramento nas águas subterrâneas da Slovenia de acordo com Gotvajn e colaboradores.…”

“…Sugere-se, ainda, verificar se as áreas com maior vulnerabilidade, apresentadas na Figura 3, coincidem com aquíferos não confinados utilizados para abastecimento público, pois uma eventual contaminação desses recursos hídricos poderia afetar a saúde dos habitantes dessas áreas (Dores et al, 2008). Tabela 2.…”

“…A intensa utilização de agrotóxicos pelas grandes culturas, a ocorrência frequente de solos de textura arenosa e média no Cerrado (Goedert, 1987) e a utilização de água proveniente de aquíferos não confinados para abastecimento público, em áreas desse bioma (Dores et al, 2008), tornam evidente a necessidade da utilização adequada e criteriosa de agrotóxicos, bem como a importância da identificação de áreas vulneráveis à contaminação.…”
