环境地球化学对人体健康的影响

人类与自然环境之间的最本质的内在联系是化学元素，环境中的化学元素通过土壤、空气、水等与人直接联系。而人体中的化学元素的含量与地球化学环境密不可分，所以，环境中的化学元素与人体健康息息相关，环境中某些化学元素组成和含量会影响到人体的生理功能和生长发育。某一地方或区域中某种元素过多则会产生毒性反应，过少或缺乏则会使人体机能出现某种障碍。研究相关的问题成为地球科学工作者面前的新课题。

RELATION OF ENVIRONMENTAL GEOCHEMISTRY TO HUMAN HEALTH

Chemical elements are the most essential bridge between mankind and natural environment. They relateto mankind with the aid of soil, air, water, etc. of the natural environment so how much chemical elementshuman bodies ultimately contain and how healthy they are closely tied with geochemical situation of theenvironment. Some elements endanger physiological functions and normal growth of man by their abnormalcomposition and proportion in the environment as certain elements in one place are over normal proportions to leadpoisonous response while in another place under normal proportions to cause physiologic obstacles. How tosolve these problems will be a new task confronting people engaged in Earth science.
