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．
Guizhou is a famous “mercury province” in China. The results of mercury smelting show that the total mercury released to the atmosphere during the mercury production in 1983 was 11 tons, and dropped to 5 tons in 1994. Since 1994, the cumulative amount of mercury released to the atmosphere has been 745 tons: 40 tons from wastewater discharge to aquatic systems: 450 tons accumulated as terrestrial ecosystems from waste sludge. In this paper, a mercury mine in Guizhou was used as a point source to study mercury pollution. The concentrations of mercury in the atmosphere and soil were changed with the change of distance. The atmospheric mercury concentration from 0.5km to 3km from the source of mercury was 180ng · m-3 ~ 20ng · m- 3; From 0.5km to 15km, the mercury concentration in soil was 146μg · kg-1 ~ 2.2μg · kg-1.
