Abstract:
Pasteurised milk--120 samples--was analysed (in Santa Fe City, Argentina) to determine organochlorinated pesticides. Almost all samples showed the presence of such residues; the compounds more frequently detected being: heptachlor and its epoxide (98%) and hexachlorocyclohexane .HCH. alpha and gamma isomers. Residues of aldrin and dieldrin; chlordane (alpha and gamma); endosulfan (I and II); DDT (o,p-DDT, p,p'-DDE, o,p-DDD, p,p'-DDD) as well as hexachlorocyclobenzene (HCB) were also found. Despite their presence high concentrations are sporadic, the mean values being less than FAO/OMS tolerance limits. Relations between maxima concentrations and seasons were not found.
