微量元素与环境

A Study on Relation between Microelement and Environment

根据近年环境科学研究的进展，概述了微量元素在环境系统中迁移、转化的条件与物理化学作用，形成微量元素在环境系统中的分布规律与区域地理特征．比较了环境背景值与污染物在环境中含量值的差异，经历了生物系统对微量元素的富集、遗传、积累，并通过食物链摄入人体，形成生命元素。由于某些生命元素值的异常，引起人体相关的疾病．由此可见，人体微量元素与环境有极密切的关系．

In this paper,a new study on relation between microelement and environment was made.It summarizes that microelements exist in our environment and can be migrated and transferred and generate some phisico-chemical reactions in certain conditions inside the environment system,and this will shape microelement of distributive status and regional geographical features. By comparing environmental background value with pollutant concentrated value,studies of microelement of concentration, heredity, and accumulation throught biological system and its intake up to human body throught food chains, biological element has been shaped. According to the recent scientific findings,some special deseases which were eoccasioning accidentally have a particular relation with bioelement of unnormal value which were sucked up to body by human. Thus we can draw a conclusion of a very close relaton between bioelement and environment.
