| 摘 要： | 通过研究太原盆地大气干湿沉降中重金属元素的含量分布特征及年输入通量，讨论其对土壤中重金属元素累积的影响。同时采用富集因子法探讨降尘物质的来源。研究结果表明，降尘中重金属元素As、Cd主要来源于人为活动，Pb的来源可能是人为源和自然源。而Hg则主要来源于自然源。

| Abstract: | The authors studied the distribution of heavy metals in dry and wet atmospheric fallouts and their annual fluxes in the Taiyuan basin and the effects of the fallouts on heavy metal accumulation in soils. In addition, they studied the sources of atmospheric fal/outs by using the enrichment factor and principal component analysis. Results show that the heavy metal elements As and Cd in the faUouts are mainly derived from human activities, Pb possibly from automobile exhaust and soils, and Hg also from polluted soils. |
