Organochlorine pesticides (OCPs) contamination was assessed in marketable species, two fishes (tilapia and catfish) and a prawn from the Lake Taabo (Côte d'Ivoire). Lindane and endosulfan were the main contaminants, suggesting their current use. DDT, endrin, heptachlor plus traces of chlordane, aldrin and fipronil were also detected. In fishes and in prawns, enzymatic biomarkers exhibited significant correlations with OCPs levels, showing the feasibility of a biomonitoring. The transfer of OCPs along the aquatic food web and their immunosuppressive effects in human are discussed. This preliminary study highlights that the pesticide contamination was concomitant with the increase in infectious diseases in the bordering population of this African lake.
对来自科特迪瓦塔博湖的可食用物种（两种鱼类，即罗非鱼和鲶鱼以及一种对虾）中的有机氯农药（OCPs）污染情况进行了评估。林丹和硫丹是主要污染物，这表明它们目前仍在使用。还检测到了滴滴涕、异狄氏剂、七氯以及痕量的氯丹、艾氏剂和氟虫腈。在鱼类和对虾中，酶生物标志物与OCPs水平呈现出显著相关性，表明生物监测具有可行性。文中讨论了OCPs在水生食物网中的转移及其对人类的免疫抑制作用。这项初步研究强调，农药污染与该非洲湖泊周边人群传染病的增加同时出现。
