摘要
通过分析降水化学成分,探讨黄山景观区域降雨的微量元素化学组成特征及其来源。结果表明,降雨中微量元素含量呈现明显的季节性变化,主要受到降雨量、pH值、风向及溶解有机质等因素影响。来源分析和贡献估算结果表明,降雨中Mn、Cu、Pb、Cd、Ni、Co等元素受燃煤和交通污染排放的影响显著,贡献率均在98%以上;土壤源和人为源对Fe的贡献率分别为76. 9%、23. 1%,对Ti的贡献率为22. 8%、77. 2%; Sr主要受海洋源(28. 3%)和人为源(70. 5%)双重影响。
In this paper, the characteristics and sources of trace elements in rainwater were discussed by analyzing the chemical composition of the rainwater collected in the northern part of Huangshan scenic spot. It was conclude that the content of trace elements showing obvious seasonal variation, and was mainly affected by rainfall, pH value, wind direction and dissolved organic matters. According to source analysis and contribution estimation, the content of Mn, Cu, Pb, Cd, Ni and Co in rainwater were caused by coal and traffic pollution whose contribution were both over 98%. Soil source and anthropogenic source contributed 76.9% and 23.1% of Fe, and 22.8% and 77.2% of Ti, respectively. The ocean source and anthropogenic source contributed 28.3% and 70.5% of Sr to the rainwater, respectively.
