ASSESSMENT OF SOIL HEAVY METAL PB, Nl & CR POLLUTION OF BEIJING

摘要：

The soil heavy metal pollution have be paid more attention because the sources of soil heavy metals become multiple and complicated with the accelerated urbanization.According to this research, Beijing is contaminated by Cr which would be reflected by the seriously pollutional Miyun County, moderate pollutional Central District and the lightly pollutional districts including Pinggu, Shunyi, Chaoyang.Fengtai, Tongzhou, Fangshan and Daxing.The districts suffered from Lead pollution are Central District, suburban region and Changping District due to high intense human activities and the rapid economic development whose heavy metal contents are distinctly higher than the background value compared with outer suburban regions.The pollution from Ni is rather light, which would be manifested by lightly pollutional Tongzhou District, and the others which are clean or micro-pollutional.
