“…The mean concentrations of o,p'-DDT was observed as 0.013 μg·g −1 in the buffalo's milk samples of the studied area which is less as reported by Ashnagar et al, 2009 [56]. Kannan et al (1992) evaluated milk from india and found levels of DDT as 0.110 mg/kg which was above those found in the present study [58].…”

The ill effects of green revolution include residues of extensively used chemical pesticides in various environmental components. The present study was designed to analyze the levels of organochlorine pesticide residues along with chemical composition in buffalo milk samples collected from different localities of Delhi. Milk monitoring can yield information about the kinds and quantities of pesticides in the environment as well as in our daily diet. In this study, the residue of three different organochlorine pesticides, namely Hexachlorocyclohexane (HCH), Dichlorodiphenyltrichloroethane (DDT) and Endosulfan have been reported. Residues of Lindane exceeded the Maximum Residual Limit values in 50% of the samples is a cause of serious concern. The p,p'-DDT was detected in 70% of the samples with p,p'-DDE (dichlorodiphenyldichloroethylene) in 80% of the milk samples of different parts of Delhi state. DDD (Dichlorodiphenyldichloroethane) another metabolite of p,p'-DDT was detected in 65% of the milk samples. The analysis indicates that DDT is the major contaminants in different parts of Delhi state. α and β endosulfan were detected in 35% and 40% of the samples analyzed. The statistical correlation shows no significant correlation between chemical compositions of the samples. The presence of multiple chemicals in virtually all samples of buffalo milk raises new questions about the possible toxicological impacts of chemical mixtures on an infant's developing nervous and immune systems and reproductive organs.

“…All the four isomers of HCH were also detected in goat tissue under present study, but at levels lower than those detected earlier, as found in the earlier reports. Similarly, the levels of lindane reported in the present study (0.002 mg/kg-0.85 mg/kg) were below the level (0.004 mg/kg -1.611 mg/ kg) reported by Al-Omar et al (1985) in lamb from Baghdad and several other workers including Kannan et al (1992), who found lindane in the range of 0.005 mg/kg -1.1 mg/kg from different locations in India. Battu et al (1984) observed that pp l DDE constituted a major share (0.047 mg/kg) in goat tissue.…”

The production commensurate with the demand for animal products including meat is increasing due to urbanization and increase in per capita income. However, meat and meat products meant for human consumption should also be safe and free from toxic contaminants. Presence of any xenobiotics in human food web is undesirable and unacceptable particularly in the wake of sanitary and phytosanitary (SPS) measures and strict regulations imposed by many countries on the ground of safety of health of the consumers. In the present study, certain organochlorinated pesticide (OCP) residues in tissues and in blood samples of goat were determined. All samples were analysed for residues of hexachlorocyclohexane (HCH) isomers, dichlorodiphenyltrichloroethane (DDT) isomers and metabolites, endosulfan isomers and metabolite, aldrin, heptachlor and dicofol. The tissue samples were extracted in soxhlet with hexane-acetone (1:1) and cleaned up by florisil column chromatography. The analysis was performed in capillary gas chromatograph equipped with electron capture detector (GC-ECD). The result indicated that 40% tissue samples were contaminated with HCH residues, while DDT and endosulfan were present in 32% samples. In blood samples, no HCH residue could be detected, but DDT and endosulfan were present in 10% and 30% samples, respectively.

Cypermethrin, chlorpyrifos and imidacloprid residues were determined in different vegetables. During 2013, samples were collected from different six major vegetable markets from Lahore. Ethyl acetate was used for extraction, whattman fluted filter and charcoal was used for cleaning procedure. High performance thin layer chromatography was used for detection, as well as quantification of pesticides. Confirmation of results was done by using gas chromatography/mass spectrophotometer. From results, it was concluded that different vegetables contain different concentration of pesticides means adsorption rate is different for each pesticide and vegetable. 79% samples were contaminated with cypermethrin, 70% from imidacloprid and 65% samples were contaminated from chlorpyrifos. Pumpkin, okra, egg plant, cucumber spinach and cabbage were contaminated with pesticides. Peeling of vegetables resulted in less concentration of pesticide.
