摘要：

Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in human milk from Chelem, Yucatan, Mexico were analyzed. Relatively high levels of p,p'-DDE, gamma-chlordane, beta-hexacyclohexane (beta-HCH) and PCB congeners 170, 28, and 44 were found. Concentration profiles by OCP groups followed the next order: Sigma DDTs > Sigma Chlordanes > Sigma HCHs > Sigma Chlorobenzenes > Sigma Drins. Total OCPs showed a decreasing tendency with number of births (primipara and multipara and age ranks) but these differences were not significant. Sigma DDT levels were lower than in other studies in Mexico, but 36% of the samples exceeded the JMPR-FAO/WHO acceptable daily intake (ADI). About 60.53% of samples exceeded the ADI value for heptachlors.
