Chlordecone is an organochlorine insecticide that was intensively used in the French West Indies to control the black weevil Cosmopolites sordidus in bananas. Its usage, however, resulted in the widespread pollution of the environment with heavy sanitary and social consequences, leading to population exposure mainly through food. Time-consuming and costly programs have been used to tackle this problem, and this study proposes to use the emerging sewage epidemiology approach to evaluate the current situation and the effect of such programs. The results determine the maximal value of chlordecone consumption, and considering the detection limit of the analytical protocol, the wastewater was found to have undetectable amounts of chlordecone. This value confirms the efficiency of the population protection strategy provided by French sanitary and environmental authorities. It also bolsters the usage of sewage epidemiology in pesticide assessment and relativizes the chlordecone risk compared to other chemicals of lesser concern.
氯丹是一种有机氯杀虫剂，曾在法属西印度群岛被广泛用于控制香蕉中的黑象甲 Cosmopolites sordidus。然而，其使用导致环境受到严重污染，带来了严重的卫生和社会后果，主要通过食物使人群暴露于其中。为了解决这个问题，人们已经采用了耗时且昂贵的方案，本研究提出利用新兴的污水流行病学方法来评估当前的情况和这些方案的效果。研究结果确定了氯丹的最大消耗量，并且考虑到分析方案的检测极限，废水中发现氯丹含量无法检测。该值证实了法国卫生和环境主管部门所提供的人群保护策略的有效性。它还支持了在农药评估中使用污水流行病学，并使氯丹风险与其他关注度较低的化学物质相比较而言更加合理化。
