环境雄激素的危害、来源与环境行为

内分泌干扰物(EDCs)因低剂量即可导致严重的生理效应而成为研究的热点,环境雄激素就是典型的内分泌干扰物之一,它主要来源于畜禽粪尿的排放以及造纸厂和城市污水处理厂处理不彻底的废水排放,污染源的连续性排放致使环境雄激素物质在各类环境介质中被不断检出,并导致一些地区出现鱼类的雄性化现象,对环境健康和生态安全构成严重威胁。综述了环境雄激素的暴露危害、主要来源以及环境雄激素在不同环境中的浓度水平和分布特征,介绍了环境雄激素的分析检测手段,阐述了环境雄激素在环境中的迁移、吸附、降解等过程,并对环境雄激素的研究进行了展望。

Effects sources and behaviors of environmental androgens

Endocrine disrupting compounds (EDCs) have been the focus because of their serious effects even at the trace level. As a kind of typical EDCs, environmental androgens mainly exist in the incomplete treated drainage of feedlot, wastewater treatment plant and paper mill. They are frequently detected in environmental matrix because of the continuous inputs, then they cause masculinization phenomenon of aquatic organisms, which have posed the potential threats on the environmental health and ecological safety. The exposure effects, the sources and the exposure levels of environmental androgens in different environmental matrices were reviewed in this paper. Moreover, the environmental behaviors of the androgens such as their sorption, transportation, degradation characters were summarized. On the basis of current studies on the environmental androgens, the tendency for the future research in this field was discussed and suggested.
