摘要
近年来,全氟及多氟烷基化合物(per-and polyfluoroalkyl substances,PFASs)的大量生产使用,使得其在自然水体中的浓度日益升高.由于PFASs的生物毒性及强稳定性,环境中的PFASs严重威胁到生态环境及人类健康.目前,多个国家及相关国际组织开始对地表水中的PFASs展开检测,但目前的监测基本属于点源监测,大范围、长时间维度的监测依然缺乏,从而无法准确揭示PFASs的时空赋存特征.本文概述了 PFASs在地表水中的赋存水平,同时阐述了地表水环境中PFASs的水平分布和垂直分布特征,并揭示了地表水中PFASs污染水平与组成的时间变化规律,总结了影响PFASs污染的主要因素,对后续PFASs监测提出了建议,以期为准确评估水环境中PFASs的污染状况提供依据.
Abstract
Recently,the mass production and usage of per-and polyfluoroalkyl substances(PFASs)have caused the serious PFASs pollution in natural water.Due to the biological toxicity and the strong persistence,PFASs pollution is threating the ecological environment and human health.Nowadays,many countries and international organizations have begun to monitor the PFASs pollution in surface water.However,the current monitoring only focus on the point source,and there still lacking the large-scale and long-term monitoring.Therefore,it is impossible to accurately reveal the spatiotemporal characteristics of PFASs pollution.This study summarizes the occurrence level of PFASs in surface water,and expounding the distribution characteristics of PFASs in the surface water.Moreover,the temporal variation law of PFASs pollution in surface water was revealed,and some environmental factors were also discussed.Finally,the follow-up suggestions on PFASs monitoring are proposed,providing a basis for accurately assessing the pollution status of PFASs in the environment.
