Since 1999, several studies have estimated chlordecone exposure among the populations of Guadeloupe and Martinique, either through direct measurement in biological matrices (blood, milk, and body fat) or indirectly by calculating dietary intake of chlordecone based on food consumption and contamination data. These studies have demonstrated confirmed exposure of the population to this pollutant. This exposure particularly affects former banana farm workers, consumers of seafood, and consumers of root vegetables in contaminated areas, with diet being the primary route of exposure today. The apparent decrease in plasma chlordecone concentrations measured since 1999 appears to align with the apparent decline in estimates of dietary exposure levels between studies conducted in 2005 and 2007. Given the risk associated with exposure to chlordecone, it is important to monitor changes in this exposure, conduct further research on potentially overexposed groups, and study the determinants of this exposure, with a view to better risk management.
