The present work has as main objective<br />investigate twelve types of pesticides (molinate, atrazine, methyl parathion, malathion, chlorpyrifos, fenitrothion,<br />pendimenthalin, triazophos, bentazone, azoxystrobin, propiconazole, difenoconazole) used in the region to assess<br />the level of contamination of waters used for potable and irrigation.Analysis of pesticides were performed using<br />chromatographic techniques (SPME-GC/MS and SPE-HPLC/DAD) through methodologies validated according<br />to parameters recommended by ABNT. Among the 60 water samples, 48 were positive for at least one of the<br />twelve active ingredients studied. Fungicides propiconazole and difenoconazole were detected more frequently.<br />The total pesticide levels ranging from 0.11-17.30 μg/L were detected in the samples. The levels detected in<br />surface and groundwater were lower than the limits established in Brazil, but 80% of the samples analyzed were<br />above total pesticide levels established by the European Community (>0.5 μg/L). Prolonged exposure to pesticides<br />can cause adverse effects to human health and the aquatic ecosystem https://ijer.ut.ac.ir/article_895_20aee3a5f4643755a79ee5f6a73050ac.pdf
