“…In the present investigation residues of endosulfan with a mean concentration of 0.0492 mg/kg were recorded. It would be worthwhile to mention here that endosulfan too, like DDT and HCH, excreted through milk in milch animals following ingestion of contaminated feed and fodder (Nag et al 2007) although the transfer coefficient (the percentage of daily intake of a pesticide excreted in milk each day) in case of endosulfan was very low (0.23-0.33%) as compared to DDT (*5%) and HCH (3-36% depending on the isomer). The presence and concentration of HCH, DDT and other OCP residues in milk in the context of present study indicate that though the frequency and level has considerably decreased over the past records of particularly India but still the contamination exists albeit in low scale.…”

Monitoring of bovine milk of different places in Bundelkhand region of India was carried out to evaluate the status of organochlorine pesticide (OCP) residues. Out of a total of 325 samples 206 (63.38%) were contaminated with residues of different OCPs. The average concentration of total HCH was 0.162 mg/kg. Among the different HCH isomers the frequency of occurrence of alpha-isomer was maximum followed by delta-, gamma- and beta. Endosulfan (alpha, beta, sulfate) was detected in 89 samples with mean concentration of 0.0492 mg/kg while total DDT comprising of DDT, DDE and DDD was present in 114 samples having mean concentration of 0.1724 mg/kg. Dicofol was positive in 17 samples.

Endosulphan residues were determined in milk samples collected from various locations of plains of Uttarakhand covering Tarai and Kumaon regions. Residues were extracted from milk by liquidliquid partition followed by clean-up by alumina column chromatography. High-performance liquid chromatography (HPLC) was used for the detection and quantification of residues. Of the total 170 milk samples collected from different species, 1.17% samples showed residues of endosulphanalpha; 2.35% endosulphan b and 4.7% milk samples showed endosulphan-sulphate residues with mean residual concentrations of 0.244, 0.566 and 0.265 lg/mL, respectively. About 6.47% of milk samples showed endosulphan residues above the maximum residue limit (MRL) of 0.1 mg/kg.

“…The dosages of acetochlor were set as 0.45, 1.35 and 4.05 g per day for the three treatment groups, in which we have made some modications on the basis of others' researches. 23,24 Acetochlor (purity 90%) (Lebont Chemicals Co., LTD Shandong, China) was placed in the water bowl, and drunk by cows through plastic jugs connected to normal drinking water nipples.…”
