Abstract
Aim:The present study was conducted to find the organochlorine pesticide (OCP) and organophosphorus pesticide (OPP) residues in fodder and milk samples along Musi river belt, India.Materials and Methods:Fodder and milk samples collected from the six zones of Musi river belt, Hyderabad India were analyzed by gas chromatography with electron capture detector for OCP residues and pulsated flame photometric detector for the presence of OPP residues.Results:The gas chromatographic analysis of fodder samples of Zone 5 of Musi river showed the residues of dicofol at concentration of 0.07±0.0007 (0.071-0.077). Among organophosphorus compounds, dimetheoate was present in milk samples collected from Zone 6 at a level of 0.13±0.006 (0.111-0.167). The residues of OCPs, OPPs and cyclodies were below the detection limit in the remaining fodder and milk samples collected from Musi river belt in the present study.Conclusion:The results indicate that the pesticide residues in fodder and milk samples were well below the maximum residue level (MRL) values, whereas dicofol in fodder and dimethoate in milk were slightly above the MRL values specified by EU and CODEX.
Highlights
Nowadays more than 800 different kinds of pesticides are used for control of insects, rodents, fungi and unwanted plants in the process of agricultural production
The average recoveries of organochlorine pesticide (OCP) in fodder were from 88.05% at 0.05 ppm and 86.71% at 0.1 ppm and in milk were from 88.45% at 0.05 ppm and 91.25% at 0.1 ppm
Average recoveries of organophosphorus pesticide (OPP) in fodder were 91.27% at 0.05 ppm and 94.67% at 0.1 ppm and in milk were from 91.25% at 0.05 ppm and 86.77% at 0.1 ppm
Summary
Nowadays more than 800 different kinds of pesticides are used for control of insects, rodents, fungi and unwanted plants in the process of agricultural production. Breeding animals and their accommodation can themselves be sprayed with pesticide solution to prevent pest infestations Both these contamination routes can lead to bioaccumulation of persistent pesticides in food products of animal origin such as meat, fat, fish eggs and milk [2,3]. Health departments used these chemicals for controlling various insects having vector role in spreading the disease like malaria, dengue fever and plague [4,5]. Many pesticides and their residues have been reported as contributory factors in several diseases such as heart disease, cancers, Alzheimer’s disease and parkinsonism [6,7].
