Quantification of Organochlorine Pesticide Residues in the Buffalo Milk Samples of Delhi City, India

Abstract

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.

Organochlorine and organophosphorus pesticide residues in fodder and milk samples along Musi river belt, India

“…The residues of o,p' DDD of 0.002 ppm was reported by Panseri [12], which is far below than the MRL level (0.05 ppm) specified by EU (CE: 698: 2005). Residue levels of P'P'-DDT of 0.038 and 0.033 ppm were reported by Mohd Aslam [19] and Kampire et al [20] respectively. Donia [16] reported 0.022 ppm and 0.032 ppm in buffalo and cow milk respectively, whereas Waliszewski et al [21] reported residue levels of 0.0372 and 0.078 in mixed milk for p,p' DDT.…”

Monitoring of organochlorine pesticide residues from bovine milk in Patna (Bihar), INDIA

“…Of 72 samples analysed, 3 from South China contained higher levels of DDT and HCH residues that exceeded the FAO/WHO accepted tolerance level. Aslam et al (2013) reported pesticide Residue levels of P'P'-DDT of 0.038 and 0.033 ppm in buffalo milk samples of Delhi city, India .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).…”

Pesticide Residues in Buffalo and Human Breast Milk of Vegetables and Fruits Farming Community at Northern of Delta in Egypt

“…Shahzadi et al [10] quantified of organophosphorous (chlorpyrifos), pyrethroid (bifenthrin, deltamethrin and lambda cyhalothrin), insecticide (imidacloprid) and carbamate (carbofuran) pesticides in cow, buffalo, goat, camel and sheeps milk collected from different localities of Lahore, Pakistan. Aslam et al [12] found that 50% of the buffalo milk samples of Delhi, India were contaminated with organochlorine pesticides residues. Dallegrave et al [16] analyzed 17 different pyrethroids and chlorpyrifos in the fat content of animal products, including beef, chicken, eggs, fish, and milk.…”

“…This information is useful to assess potential health risks associated with the contribution of milk consumption for pesticides intake into the human either for babies or during the following age stages. So, determination of environmental chemicals in the common milk types are of broad scientific interest [12]. So this study aimed to investigate the residual levels of pesticides, including representing group of persistent organochlorine compounds beside certain pesticides of organophosphorous and pyrethroids (which are currently applied in agricultural practices) in milk of buffalo and human living in selected rural areas in Egypt.…”

“…Kara et al [11] investigated the Th presence of Th OPPs; malathion and Th malaoxon residues in Th buffalo and Th cow milk products in Th the Th western Turkey. Aslam et al [12] quantified some of organochlorine pesticide residues in the buffalo milk samples of India. Regarding the studies which carried out on the human breast milk, [13] detected OCPs (for example, total DDTs) in breast milk of lactating mother at the main levels of 1315, 113.7 and 517.3 ng/g fat, respectively.…”
