    Abstract:
    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: SigmaDDTs > SigmaChlordanes > SigmaHCHs > SigmaChlorobenzenes > SigmaDrins. Total OCPs showed a decreasing tendency with number of births (primipara and multipara and age ranks) but these differences were not significant. SigmaDDT 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.
