Analytica lresults show thatsoiol of the contaminated area was
polluted with high concentration of endosulfan isomers and its
metabolite endosulfan sulfate(α endosulfan: 27–199ngg1 β
endosulfan: 4–739ngg1 and endosulfan sulfate:24–904ngg1)
when compared with control soil (ND-0.09pgg1), and the soil
with cropsreceivingpesticideapplication(0.46–24.4 ngg1).
