摘要
氯是一种重要的微量元素，它的环境污染以大气污染最为严重，其次是废水和废渣的污染。环境中的氟过量会引起生态环境变化，甚至破坏生态平衡。本文以较详实的材料阐述了氟在环境中的来源、分布、迁移和转化规律以及氟的主要环境化学特性及其对植物、动物和人体正常生理机能的影响和危害。
Fluorine is an important kind of trace elements in natural environment and its pollu-tion chiefly occurs in atomsphere、sewage and solid waste. Excessive amounts of fluorine will cause the change of ecological environment, and even break the ecological balance in certain re-gions、This paper deals with and discusses in detail the sources distribution、transfer and transi-tion laws of fluorine in all kinds of environments,and its main environmental-chemical proper-ties as well as its effects and harm to plants、animals and human beings.
