摘　　要：贵州是我国著名的“汞省”，汞冶炼的结果表明：1983年汞生产过程中向大气散布的总汞是11t，1994年下降到5t．自从1994年以来，汞散布到大气的累积量是745t：从废水排放到水生系统是40t：以废渣形式累积到陆生生态系统的是450t．本文以贵州某汞矿作为研究汞污染的点源，研究大气和土壤中汞浓度随距离的变化而改变，从距汞源0.5km到3km大气汞浓度是180ng·m－3～20ng·m-3；从0.5km～15km，土壤中汞浓度是146μg·kg－1～2．2μg·kg-1．Total mercury emissions to air from the mercury producing processes in Guizhou, the main Hg production province of China, has been estimated to be 11 tons in 1983 and down to 5 tons in 1994based on mainly the statistics data obtained from five main Hg Producers in the province. The total historical chssion of Hg to the air was eSthated to be 754 tonS, discharged in form of waste water to the aquatic system was aboul 40 tons and ascumulated in form of waste solid to the terrestrial environment was aboat 450 tons since 1949.Danzhai mine, one of the five main Hg producers in the province, was studied as a point sources of Hg pollution. Hg concentraions in the air vary from 180 ng m-3(0.5 km)to 20ng m-3(3km).Hg contents in the soil vare from 146μg g-1(0.5 km)to 2.2 μg g-1(15 km).
