Abstract
Astudy was conducted forthe qualitative and quantitative estimation of 51 pesticides comprising 16 organochlorines, 23 organophosphates, eight synthetic pyrethroids and four herbicides in commonly consumed green vegetables i.e spinach, coriander, chilli, ladyfinger, bottle gourd and bitter gourd collected from various tehsils of Satna district, Madhya Pradesh. Gas chromatography-Electron Capture Detector (GC-ECD), Flame Photometric Detector (GC-FPD) were used for estimation of pesticides and Gas chromatography-Mass Spectrometry (GC-MS) was used for confirmation. Out of 144 samples, 59 samples were found contaminated with pesticide residue. It was observed that most of the bitter gourd samples were contaminated with chlorpyrifos whereas spinach and okra were contaminated with cypermethrin. Nagod samples were found most contaminated (10 out of 18) whereas Rampur Baghelan were least contaminated (6 out of 18). Contamination of chlorpyrifos was predominant in samples of Nagod, Raghurajnagar and Birsinghpur whereas cypermethrin contamination was so in Majhagawa samples. Profenofos and monocrotophos were detected only in Nagod and Raghurajnagar samples.
