- Pesticide residues of most commonly used classes were analysed in soil samples collected from Wurno irrigation field. All the 17 soil samples analysed were found contaminated with used pesticides (i.e dichlorvos, mevinphos, dimethoate, femitrothion, chlorpyrifos, endosulfan, methylparathion, profenofos, γHCH, DDT, dieldrin, endrin and drins), and varying degree of contaminants and frequency were found in the top soil. The most widely detected pesticide residue was DDT found in 16 samples with a mean level of 2.22 measuring a total of 24.10% of the detectable residue, the second most detected pesticide residue was chlorpyriphos, having a total of 17.04% of the detectable residue. γHCH was the third most detectable residue in the sample with a total of 14.77% of the detectable residue. Analysis also showed that the two fallow soil samples have very low levels (< 1%) of the total detectable residues.
