The study was aimed to determine the concentrations of organochlorine pesticides (OCPs) in bovine milk (both branded and unbranded) collected from in and around Tiruchirappalli city, Southern India. The results of the present investigation indicated that these milk specimens were found to be contaminated with 7 different pesticides. Mirex (higher incidence), Heptachlor, o,p’-DDD, o,p’- DDE, Aldrin, cis and trans-chlordane were detected in the milk samples. The residues were quantitatively determined using Gas Chromatograph-Mass Spectrometer-Quadrupole on electron ionization (EI) mode. The study showed that unbranded milk samples contained higher concentrations of residues than branded. The derived average daily intake of aldrin and DDT has exceeded WHO’s Acceptable Daily Intake.
