Abstract

The presence of pesticide residues in food commodities has always been a matter of serious concern. Farmers apply pesticides repeatedly to ward off the pest and pick the vegetables at short intervals. The samples of vegetables were collected from market in three blocks of Samastipur district purposively as per multistage random sampling design to monitor the residues in market vegetables. GC-MS analysis was applied for evaluation of pesticide residues in the sample. The data obtained so far showed that out of 50 samples of vegetable analyzed 24 (48%) were contaminated with different pesticides and 3 samples (6%) samples contained residues above MRL. The overall pesticide occurrence was in the order as Endosulphan > Quinalphos > Dimethoate > Chlorpyriphos > α-HCH > δ-HCH > β-HCH. Pesticide contamination was higher in cabbage than cauliflower.
