摘要：

大气颗粒物是大气质量评价中的一个通用的重要指标,近年来,对于大气颗粒物污染这一热点问题开展了大量的研究。文中选取辽宁省沈阳市、锦州市和葫芦岛市等典型地区研究大气颗粒物(TSP、PM10、PM25)中Cd等重金属元素的分布特征。结果表明，辽宁省大气可吸入颗粒物中 Pb和 Zn的含量最高,其次是 Cu、 Mn、 As、 Cr、Cd。燃煤、 燃油和工业污染源等方面可能是造成这些元素含量较高的主要原因。此外,文中还对大气颗粒物对土地质量的影响研究进行一些有益尝试。研究表明，大气颗粒物中重金属元素含量对土地质量的影响是显而易见的。政府管理部门应该重视对大气颗粒物中重金属元素含量的监控,努力减少其对土地质量的影响。

Abstract:

Atmospheric particulate matter is one of the important common indicators for air quality assessment. Recent years, many researchers have studied the hot issues of atmospheric particulate matter pollution. In this paper，we selected the cities of Shenyang, Jinzhou and Huludao in Liaoning province to study the distributional characteristics of heavy metal elements in atmospheric particulate matter(TSP,PM10,PM2.5). It shows that the content of lead or zinc in the respirable particulate matter is the highest one, and the contents of copper, manganese, arsenic, chrome and cadmium are the higher ones. This perhaps results from coal combustion, oil combustion and other industrial sources of pollution. Furthermore, we have studied the impact of atmospheric particulate matter on land quality. It was concluded that the content of heavy metal element in atmospheric particulate matter has a significant correlation with the corresponding element content in soil, and the influence of atmospheric particulate matter on land quality is obvious. We suggest that the administration should pay much attention to monitoring the contents of heavy metal elements in atmospheric particulate matter to reduce their influence on land quality.
