Maternal and umbilical cord blood plasma organochlorine levels are described for Inuit, Dene, Metis, Caucasian and Other non-Aboriginal participants. Overall 523 women volunteered to participate by giving their written informed consent between May 1994 and June 1999: resulting in the collection of 386 maternal blood samples, 407 cord blood samples and 351 maternal\/cord pairs. Nearly half of all the participants regularly smoked cigarettes, including 77% of the Inuit participants. Maternal and cord results are presented for PCBs (as Aroclor 1260 and 14 congeners) and organochlorine pesticides, including p,p&rsquo;-DDT, p,p&rsquo;-DDE, beta-hexachlorocyclohexane (beta-HCH), hexachlorobenzene (HCB), cis and trans nonachlor, heptachlor epoxide, oxychlordane, mirex, dieldrin and toxaphene. Maternal PCB levels (as Aroclor 1260) averaged 4.42 (+\/-9.03) mug\/l in Inuit, which was 3.3 times higher than those found in Dene\/Metis, and 3.4 times higher than levels in Caucasians. Mean DDE levels were 2.8 times higher in the Other non-Aboriginal group (Chinese, Filipino,. East Indian and multiple ethnicity) than in the Inuit group, at 3.99 mug\/l and 1.42 mug\/l, respectively. Cord blood PCB levels (as Aroclor 1260) averaged 1.16 (+\/-2.42) mug\/l for Inuit participants, which was 3.3-4 fold higher than the other ethnic groups. PCBs, pp&rsquo;-DDE and hexachlorobenzene were detected in all maternal samples, and pp&rsquo;-DDE was detected in all cord samples. Regression coefficients for maternal\/cord pairs are presented for selected organochlorines. Other results from this study, including maternal and cord metals data, will be presented elsewhere.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54654","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"WALKER JB,J WALKER & ASSOCIATES
