摘要
选择大气污染严重的焦作市为研究区,通过布点监测,分析了不同区域大气TSP和降尘的污染状况及月变化趋势,测定了大气沉降中Hg、Cd、Pb三种重金属的含量,并计算出大气沉降对土壤重金属的年输入量分别为Hg4.43g/(hm2·a)、Cd5.70g/(hm2·a)、Pb394.6g/(hm2·a);不同区域大气污染状况与大气沉降输入土壤重金属的量顺序均一致为演马矿和朱村矿较高,近郊和市区次之,远郊和公园最低。
Jiaozuo city is one of the cities with most serious air pollution at home and abroad. In the paper Jiaozuo was selected as research area. The TSP and dusffall was serially monitored in different type districts. The contents of Hg Cd and Pb were analyzed in air settlement. The results showed that import amount of Hg Cd and Pb lead on soil were Hg4.43 g/（hm^2.a）,Cd5.70 g/（hm^2.a）,Pb394.6 g/（hm^2.a）; their amount was unanimous with pollution levels of air. Its order was Yanma mining area and Zhucun mining area〉the suburbs and the city proper〉outer suburbs and park.
