不同环境介质中有机磷酸酯赋存状况和源解析研究

Research of Organophosphate Esters in Different Environmental Media

有机磷酸酯(organophosphate esters,OPEs)具有神经毒性、内分泌干扰活性和生殖毒性等毒害作用,其环境残留对生态安全和人类健康方面引起的潜在风险备受关注。本文从产品释放、环境排放以及环境多介质模型预测等方面阐述OPEs的污染赋存特征和环境迁移的主要途径。研究发现,OPEs的主要输入源是产品使用中的释放和点源、面源途径的环境排放,赋存在沉积物中的OPEs种类最多。收集和分析OPEs的环境赋存信息,可为建立和完善该类新污染物的风险管控体系提供参考。

The potential risks caused by the environmental occurrence of organophosphate esters(OPEs)have attracted much attention,because OPEs have toxic effects such as neurotoxicity,endocrine disrupting activity and reproductive toxicity.The pollution occurrence characteristics and migration transformation pass of OPEs were analyzed from the aspects of product release,environmental discharge,and multimedia model prediction.It was found that the major sources of OPEs focused on environmental release and product emissions,meanwhile the largest number species of OPEs occurred in sediments.Environmental occurrence information of OPEs could provide references for the establishment and improvement of the risk control of emerging pollutants.
