The residue analyses revealed that 42 out of the 76 farmers had residues of diazinon, endosulfan, propoxur and lindane in their blood; and 47.6% out of these farmers belonged in the >20 years exposure duration period. About 34% of the farmers had diazinon with a mean concentration of 0.067 mg kg−1, 29% endosulfan (mean = 0.033 mg kg−1), 23% propoxur (mean = 0.095 mg kg−1), and 17% lindane (mean = 0.080 mg kg−1) in their blood. The residues of lindane, endosulfan and propoxur in all the exposure duration categories were found to be far below the no observable adverse effect level (NOAEL) while diazinon residues detected in the blood serum of the farmers in all the exposure duration categories exceeded the NOAEL of 0.02 mg kg−1 for the insecticide. The study also revealed that the sources of drinking water had been contaminated with dazinon and propoxur in some of the farmers’ localities; and the concentrations of the insecticides exceeded the acceptable daily intake (ADI).
