摘要
Researches have been carried out in the framework of the French Initiative for Coral Reefs in order to assess the pollution levels of the coral reef trophic webs by pesticides in French Polynesia. An overall contamination with critical organisms from various levels of the trophic web was shown. On one hand, analysis showed a contamination by chloroacetamide and triazine derivatives, two major families of herbicides. On the other hand the occurrence of organochlorine insecticide has proven ubiquitous. Especially worrying is our finding of chlordecone (kepone (R)) occurrence in all of the organisms investigated, mainly in fishes, which are commonly ingested by the local inhabitants. Moreover, these data are very worrying as the average residence time of chlordecone in sediment numbers in thousand of years.
