运用ICP-MS和ICP-OES分析了攀枝花市不同时段不同地点大气降尘中重金属元素含量,并对大气降尘中重金属的地球化学特征进行了分析,得出以下结论:①攀枝花市大气尘中As、 Co、 Mn、 Pb、 Ti、 V的含量,与四川省其他城市相比均偏高,Zn的含量相对较低;②Cd、 Mn、 Pb主要分布在冶炼区和石灰石矿区,Co、 Cu、 Ti主要分布在石灰石矿区, Cr和V主要分布在冶炼区, As在仁和河富集较为富集, Zn集中在排土场附近, Fe集中在冶炼区和煤矿区;③除Pb外,其余十种元素旱季含量基本都高于雨季,而雨季Pb的含量却明显高于旱季.通过主成份分析,得出了在攀枝花市大气降尘中,重金属元素的来源主要为矿山污染和开采过程中产生的废水、废气.

The samples of atmospheric dust which we collected in Panzhihua at different times in different locations were analyzed by ICP-MS and ICP-OES. We also analyzed the geochemical characteristics of heavy mental elements in atmospheric dust and concluded that compared with other cities in Sichuan Province, the content of As、Co、Mn、Pb、Ti、V was on the high side, Zn is relatively low. Cd, Mn, Pb mainly distributed in the smelting area and limestone mining, Co, Cu, Ti mainly distributed in the limestone mining area, and Cr and V mainly distributed in the smelting area. As is more enriched in Renhe River, Zn concentrated in the Dump nearby, and Fe concentrated in the smelting area and coal mining area. Except to Pb, the content of other 10 kinds of elements in the dry season were basically higher than the rainy season, while content of Pb in the rainy season was significantly higher than the dry season. Through the principal component analysis, the main sources of heavy mental elements in atmospheric dust are pollution and exploitation of the mine、waste water and waste gas aroused from mining.
