天津市城区大气干湿沉降地球化学研究
Study on the Dry and Wet Atmospheric Deposition in the Urban Area of Tianjin
摘要
Abstract
In order to find out how the elements host and transfer in the air of Tianjin urban area, we carried out a annual sample collection of dry and wet atmospheric deposit and subsequent study based the data. The results show: (1)the concentration of Cd, Hg, Zn, S in dry and wet atmospheric deposit is more than 10 times of the back-ground concentration.(2)Coal combustion is important source of dry and wet atmospheric deposit.(3)deposit weight and elements concentration in it have high correlation with nearby environment, the heavy metal concen-tration of deposit in industry area is much higher than others.(4) we found out that dry and wet atmospheric depo-sition would change the elements concentration of top soil remarkably based on modeling and calculation, which also confirm the deposition is important cause of heavy metal accumulation in urban and suburb soil of Tianjin.关键词
