Pesticide residues in rice, wheat and pulses of Bidar district of north Karnataka were evaluated in this study. Organophosphates (OP), Organochlorines (OC), Synthetic pyrethroids (SP) and carbamate residues were monitored. A total of 250 samples from different markets of Bidar district, Karnataka were analysed by gas chromatography (GC) and high performance liquid chromatography (HPLC). Recovery studies carried out for all 4 groups of pesticides were within the acceptable range of 70-120% before the analysis of field samples. Sample extraction and partitioning was carried out by multi residue method. Among the samples analysed, 80 samples were found to be contaminated with different groups of pesticides. Pesticide residues were found to be above the Maximum Residue Limit (MRL) in 22 samples and below MRL in 58 samples. More numbers of pesticides were detected in wheat followed by rice and pulses. In pulses, red gram was the major commodity contaminated with multiple pesticide residues followed by black gram and green gram. OP pesticides were dominated OC and SP in all the studied commodities. Most commonly detected OPs were chlorpyrifos, parathion, profenofos, ethion and triazofos.
Key words: Pesticides, GC, HPLC, pulses, rice and wheat
