Relationship of Thyroid Hormone Levels to Levels of Polychlorinated Biphenyls, Lead, <i>p,p</i> ′ <i>-</i> DDE, and Other Toxicants in Akwesasne Mohawk Youth

Abstract

Our results demonstrate a reduction in thyroid function in adolescents in relation to their current serum levels of PCBs. These observations are consistent with the hypothesis that pre-natal exposure to PCBs alters thyroid function in a long-lasting manner but does not exclude the possibility that postnatal exposure is influential also.
