环境中重金属的污染对人类的生活及健康有着极为密切的关系,而且重金属在体内可以蓄积,并能引起人体急性或慢性中毒,有的重金属甚至是人类致癌、致畸、致突的重要原因之一。 由于某些经常向环境中排放含有各种重金属的废气、废水、废渣的工厂企业尚未彻底治理。汽车尾气的排放也日益增多,因而对大气飘尘中重金属的监测,对于治理环境污染有着重要意义。为此,我们于1980年11月对长春市大气飘尘中铅、汞、镉、铜、铁、锌等六种重金属的污染情况进行了初测。
Heavy metal pollution in the environment has a very close relationship with human life and health, and heavy metals can accumulate in the body, and can cause acute or chronic human poisoning, and some heavy metals and even human carcinogens, teratogenic and sudden cause of sudden one. Since some factories and enterprises that regularly discharge the exhaust gas, waste water and waste residue containing various heavy metals to the environment have not yet been thoroughly controlled. The emission of automobile exhaust gas is also increasing day by day. Therefore, the monitoring of heavy metals in atmospheric fly ash is of great significance for environmental pollution control. To this end, we conducted a preliminary test on the pollution of six heavy metals such as lead, mercury, cadmium, copper, iron and zinc in the atmospheric fly ash of Changchun in November 1980.
