摘要
人体与地壳元素组成规律相似。环境与人体微量元素处于动态平衡的关系。若人类的正常生活环境发生异常变化，环境中的微量元素就会随之出现过多或过少的失衡状态，于是人体内微量元素的含量比例也即失调。结果机体的生理平衡也将遭到破坏，从而导致各种危及人体健康的有害后果。
The composition rule of the earth's crust elements and human body's microelements are same. There is dynamic equilibrium between the environment and humen body's microelements. If normal environment changes, the microelements in the enviroment will lose their balance. And the rate of microelement in humen body will be unbalanced immediately. Finally, the physiological balance of organisms will be destroyed,thus leading to all kinds of harmful results to the health.
