Extensive use of pesticides on vegetables started gaining momentum and continued its up-trend in India.The use of pesticides in agriculture concern of residue accumulation, which may remain in the food and agricultural environment causing human health and damaging ecological balance. This study reported is based on the determination of pesticide residue in cauliflower and brinjal. Cauliflower and brinjal were purchased from local market and analysed for their residual contents of chlorpyrifos and cypermethrin. The pesticide residues were extracted from the cauliflower and brinjal with ethyl acetate and cleaned-up with ethyl acetate and hexane (3:7 v/v) mixture using florisil and charcoal column and determination was carried out on GC-ECD. Recoveries of these residues are over 90% with coefficient of variation below 5%. The method is suitable for the analysis of in cauliflower and brinjal with high sensitivity and accuracy. Source
