Organochlorine pesticides in Argentinian butter.

Abstract

Organochlorine pesticide residues were analysed in 150 samples of butter collected from several places in the cities of Santa Fe and Rosario (Argentine Republic) over a period of 18 months. Pesticides analysed in butter were: HCH (alpha and gamma isomers), heptachlor and its epoxide, aldrin, dieldrin, and DDT (p,p' DDE, o,p' DDT and p,p' DDT). Most samples contained residues of gamma-HCH (Lindane) and heptachlor (92% and 78%, respectively); alpha-HCH and aldrin were detected in 58% and 55% of samples; dieldrin, heptachlor epoxide, DDT isomers were found in few cases (30%). Mean values of pesticides residues in butter fat were: sigma HCH 0.029 ppm; sigma heptachlor 0.064 ppm; sigma aldrin 0.11 ppm and sigma DDT 0.024 ppm. Residue levels exceeded the limits prescribed by the Food and Agricultural Organization/World Health Organization in only very few cases.
