The Kannari Study: Health, Nutrition, and Exposure to Chlordecone in the French West Indies includes a "contamination" component whose objectives are to describe the contamination of the West Indian population by chlordecone and other organochlorine compounds (PCBs, HCH, HCB, DDT, DDE) and to quantify the determinants of chlordecone exposure levels. The results of the Kannari study show that biological exposure to chlordecone is widespread and varies significantly among study participants. The measured exposure levels appear to indicate a decrease in background exposure over the past ten years, but certain population subgroups remain highly exposed: five percent of participants have exposure levels at least ten times higher than the average concentration. Population exposure levels are comparable between the two islands. They are determined primarily by dietary exposure but also by place of residence. These results are largely consistent with the work of ANSES. In particular, the consumption of fresh fish from informal channels is associated with higher body burden levels (the influence of fish species could not be studied due to sample size limitations). Furthermore, living in areas contaminated with chlordecone is associated with higher body burden levels. In contrast, the consumption of roots and tubers is not associated with an increase in body burden. It should be noted that, in the absence of an established critical body burden value, it is not possible to estimate a health risk based on these body burden data. The results of the Kannari study provide the first description of the body burden of the general population of Guadeloupe and Martinique with regard to chlordecone and certain organochlorine compounds. These results complement the findings from other components of the Kannari study, which present health data on the Caribbean population, dietary habits and their trends, as well as data on dietary exposure to chlordecone, including identification of the main contributors.
