Monitoring of seasonal vegetables for pesticide residues.
Market samples (60) of six seasonal vegetables were monitored during 1996-1997 to determine the magnitude of pesticidal contamination. The estimation of insecticide residues representing four major chemical groups i.e. organochlorine, organophosphorous, synthetic pyrethroid and carbamate, was done by adopting a multiresidue analytical technique employing GC-ECD and GC-NPD systems with capillary columns. The tested samples showed 100% contamination with low but measurable amounts of residues. Among the four chemical groups, the organophosphates were dominant followed by organochlorines, synthetic pyrethroids and carbamates. About 23% of the samples showed contamination with organophosphorous compounds above their respective MRL values. More extensive studies covering different regions of Haryana state are suggested to get a clear idea of the magnitude of vegetable contamination with pesticide residues.
