多环芳烃的致癌性机制研究进展

Mechanism research progress of carcinogenicity of polycyclic aromatic hydrocarbon(PAH)

多环芳烃是一类被国际社会特别关注的持久性有机污染物,是最早被发现的具有"三致作用"的环境污染物之一。其广泛存在于多种环境介质中,虽然量少,但不断地生成、迁移、转化和降解,并通过呼吸道、消化道、皮肤等途径进入人体,极大地威胁着人类的健康。

Polycyclic aromatic hydrocarbon is a persistent organic pollutant that has been specially concerned by international community, it is one of the earliest found environmental pollutants with three-inducing impact.It widely exists in various environmental media although the number is small, but with continuous generation, migration, transformation and degradation, it＂enters human body through the ways such as respiratory tract, digestive tract, and skin, which greatly threatens human health.
