Abstract
The use of pesticide in agriculture avoid the loss of foods but their residues may contaminated the environmental mainly the soil. This study proposed to evaluate the possible soil contamination by endosulfan and its principal metabolite, endosulfan sulphate. The experiment was carried out with soybean in area of 900m2 separated in three equal parts: control (without inseticide application), pests integrated management (PIM) and conventional systems, sprayed with 437g i.a./ha e 1312g i.a./ha, respectively. The endosulfan was quantified by gas chromatography with electron capture detector (Ni 63) seven days and one year after each spray. The endosulfan residues were not detected in the soil (10-20cm) cultivated with soybean in MIP system (10-20cm), within the limit of method uantification [α-endosulfan (0.005µg/g), β-endosulfan (0.005µg/g) e sulfato de endosulfan (0.1µg/g)]. The total endosulfan residue was 0.06µg/g to PIM in depth (0-10cm) and to conventional 0.14µg/g in (0-10cm) and 0.03µg/g in (10-20cm). After one year, none residue was detected in soil (0-20cm) for two systems. Both treatments were efficient to pests control, however PIM was suggested to use, because it result in low contamination level of soil by endosulfan.
