Monitoring and preventive measures about heavy metal pollution

摘要

Taking overmuch in toxic heavy metal elements will lead to reduce of personal immunity or become permanently disabled, even death. In local region, the soils and water bodies which persons rely for existence had been contaminated, which the toxic heavy metal elements had been accumulated over a long period of time because it is difficult to degradation by microorganism, and even a local “time bomb” of geochemical field will may be formed. In certain period it will suddenly appear so that to form extensive epidemics. They can be transformed between heavy metal pollutions in soils and water and air, in which the soils pollution is most serious in consequence and is difficult to restore. When the heavy metal pollutions of soils very serious, it can be led to food chain poisoning, reduction of the body diathesis of local population and addition of children with disease, and that offend of the heavy metal elements in local grain crops and vegetables and affect edible. In the course of industrialized society of our country, therefore, it is a very important work that strengthen the prevent measure of the extent of the heavy metal pollutions in soils and water and air, which it is an important guarantee of the ensure sustainable society development. Regional geochemistry is the foundation work of the effective monitoring in detection of soils and water bodies (including groundwater) so that a system of the prevent measure can be established as soon early as possible.
