多氯联苯(PCBs)是一组氯代烃类化学物质,作为一种常见的环境污染物,其物理化学性质决定了它们能够持久地存在于环境中并具有生物蓄积性。它可以通过大气、土壤、动植物产品和食品等多种暴露途径进入人体并在体内富集,对人类健康产生不良影响。本文综述分析报道近年来有关PCBs影响内分泌系统的实验研究、人群暴露效应及相关机理的研究进展。 Polychlorinated biphenyls (PCBs) are a group of chlorinated hydrocarbon chemicals that, as a common environmental pollutant, whose physicochemical properties determine their ability to persist in the environment and have bioaccumulation. It can enter the human body through a variety of exposure pathways such as the atmosphere, soil, animal and plant products and foodstuffs and accumulate in the body, adversely affecting human health. This review summarizes and reports on the recent progress in research on the effects of PCBs on the endocrine system, population exposure effects and related mechanisms.
