摘要
本文收集了成都市2008年全年雨水样品,采用ICP-MS方法测定雨水溶解态的Fe、Al、Mn、Pb、Zn、Cu等重金属离子,通过分析重金属的来源及变化规律,阐述了成都市雨水的重金属含量特征。发现成都市雨水中Fe、Mn、Pb、Cu等重金属含量高于地表水,雨水中重金属的含量受人为因素影响明显,汽车尾气、燃煤是其主要来源。研究工作为成都市大气中重金属污染评价及污染治理等提供了理论依据。
Samples of rainwater in the whole year of 2008 in Chengdu were collected. The method of ICP-MS was adopted to measure dissolved Fe, Al, Mn, Pb, Zn, Cu, and other heavy metal irons in rainwater. Through analyzing the sources of these heavy metals and their variation laws, the characteristics of heavy metal contents in rainwater from Chengdu were expatiated. It is found that the contents of Fe, Mn, Pb, Cu, and other heavy metals in rainwater from Chengdu are higher than those in surface water. The contents of heavy metals in rainwater are affected by human factors. Automobile exhaust and coal combustion are the main sources. Theoretical basis is provided for the assessment of heavy metal pollution in the air of Chengdu and pollution treatment.
