摘要
选择大气污染严重的太原市为研究区，通过定点监测，分析了不同类型区大气ＴＳＰ和降尘的污染状况及周年内的月变化趋势，测定了大气干湿沉降中 Ｈｇ、 Ｃｄ、 Ｐｂ三种重金属元素的含量，并计算出大气干湿沉降对土壤系统重金属的年输入量分别为Ｈｇ４．４８ｇ／（ｈｍ２·ａ）， Ｃｄ６．３４ｇ／（ｈｍ２·ａ）， ｐｂ３４９．４ｇ／（ｈｍ２·ａ）；不同类型区大气污染状况与大气沉降输人土壤中重金属累积顺序一致均为工矿区＞城区和近郊区＞风景区＞远郊区。
Taiyuan city is one of the most serious air pollution in the world. In the paper Taiyuan was selected as research area. The TSP and settlement was series monitoring in different type district. The contents of Hg Cd and Pb was analyzed in air settlement. The results showed that import amount of mercury, cadmium and lead on soil were 4.48 g/(hm2·a), 5.79 g/(hm2·a) and 347.19 g/(hm2·a). their amount was unanimous with pollution levels of air. Its order was industry district>the city proper and the suburbs>Jinci scenic spot>outer suburbs.
