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.
