Abstract:
The present study was conducted to find the organophosphorus pesticide (OPP) residues in milk samples along Musi river belt, India. Milk samples collected from the six zones of Musi river belt, Hyderabad India were analyzed by gas chromatography with electron capture detector and pulsated flame photometric detector for the presence of OPP residues. The gas chromatographic analysis of milk samples of Zone IV of Musi river showed the residues of Quinolphos at concentration of Quinolphos 0.06 ± 0.015 (0.04-0.08) ppm. The residues of Dichlorovas, Phorate, Methyl parathion, Fenitrotion, Profenphos, Ethion, Phosalone, Lambda Cyhalotrin were below the detection limit in the remaining milk samples collected from Musi river belt in the present study. The results indicate that the pesticide residues in milk samples were well below the maximum residue level (MRL) values, whereas Quinolphos in milk was slightly above the MRL values specified by European Union (EU).
