The Centers for Disease Control in 2003 established a national baseline of exposure to forty polychlorinated compounds including PCBs and dioxin. None of the compounds were found above the detection limit in more than half the members of the racial groups examined (i.e., Mexican-American, non-Hispanic Black, and non-Hispanic White). However, at the 95th percentile, nineteen of the compounds were present. The highest levels for each of the nineteen compounds were found in non-Hispanic Blacks.

This presentation will identify: a) the possible sources of exposure to polychlorinated compounds b) the likely role of animal fat as the primary source of exposure contributing to higher levels of polychlorinated compounds in a subpopulation of non-Hispanic Blacks relative to other racial groups; c) the underlying factors (e.g., poverty, subsistence angling, etc.) that result in such a diet for a subpopulation of non-Hispanic Blacks; and d) actions EPA is taking, and can take, to minimize greater exposure to persistent and bioaccumulative polychlorinated compounds in a subpopulation of non-Hispanic Blacks. Finally, using the EPA action model, we will recommend approaches other agencies can take to minimize exposure to polychlorinated persistent, bioaccumulative, and toxic compounds among populations at-risk for exposure.

Learning Objectives:

• Identify sources of exposure to polychlorinated compounds
• Assess social (e.g., race, class, etc.) factors affecting exposure
• Recommend actions to minimize disparate exposure
