氟的环境地球化学行为及其对生态环境的影响
|
摘要
近几十年来,氟的区域性环境地球化学异常和人为环境污染所导致的植物和人体氟暴露现象引起了广泛关注,世界各国学者对不同环境介质中氟的地球化学行为进行了较为深入的研究,但仍然存在诸多争议和不确定性.本文回顾了近些年来有关氟在大气、水、土壤中的来源、数量、存在形态、迁移转化和控制因素等方面的研究成果,以及氟的地球化学行为与植物和人体氟暴露的关联性,并提出了未来有关氟的环境地球化学行为研究应优先考虑的几个方向.
In past decades,fluorine exposure of plants and human caused by regional geochemical anomalies of fluorine or environmental pollution has received widespread concerns. Many in-depth researches have been conducted on the geochemical behavior of fluorine in different environmental media,but with disputes and uncertainties. We reviewed the research advances on geochemical behaviors of fluorine in the atmosphere,water and soil,including source,quantity,existence form,migration,transformation,and controlling factors. The observation of correlation between geochemical behaviors of fluorine and plant and human fluoride exposure was also reviewed. Moreover,we proposed that the future research on environmental geochemical behaviors of fluorine should give priority to particular directions.
