Persistent organic pollutants(POPs),such as dioxins,polychlorinated biphenyls(PCBs) ,and organochlorine pesticides(OCPs),which are synthetic chemicals or by-products with an intrinsic resistance to natural degradation processes,are released into the environment,resulting in the widespread dispersal and accumulation in the environment,as well as in human and ecological food *** to their ubiquity in the environment and lipophilic properties,there is emerging concern over the potential risks of human exposure to *** growing evidence indicated that exposure to POPs might be strongly associated with increased risk of a worldwide epidemic of diabetes,especially type 2 diabetes,suggesting that POPs might play a key role in their *** on summary of the related studies,this paper reviews the epidemiologic and experimental data that addresses the association between increased risk of diabetes and POP exposure,including dioxins,PCBs,OCPs,polybrominated flame retardants(PBFRs),and some environmental *** potential mechanisms whereby POPs cause diabetes were discussed,such as alterations in lipid metabolism,in glucose transport,in insulin signaling pathway,in steroid metabolism,and disruption of endocrine system,induction of tumor necrosis factor-α(TNF-α) .However,with respect to diabetes,some of the evidence on POPs linked to risk of diabetes was suggestive of a direct or indirect association but was limited or *** research is urgently needed for determining the relative contribution of POPs to diabetes and elucidating the exact mechanisms.
