Persistent organochlorine (OC) compounds such as DDT and its derivatives, isomers of hexachlorocyclohexane (HCH), hexachlorobenzene (HCB) and polychlorinated biphenyls (PCBs) may pose toxicological and ecological impact due to their persistence in some biological compartments. Despite the fact that agriculture has discontinued the use of the majority of these pesticides in many countries, the considerable differences in their concentrations in samples of human and animal origin are evidence that biological magnification via the food chain still exists in the case of OC compounds. This phenomenon may by illustrated by the close relationship between OC compound concentration in the fat of human and cow milk. The purpose of the present study was to determine the rate of excretion of the OC pesticide complex including their metabolites in the perinatal and postnatal period during various gland secretion phases.
