| Abstract: | Urban soils are regarded as recipient of large amounts of heavy metals from various sources.Information on the environmental effects of different functional zones is lacking,especially in Yibin,a city with a rapidly increasing rate of development.Such information will assist in developing strategies to protect urban environment against long-term hazardous accumulation. In order to identify the concentration and spatial distribution of Zn in urban soils,63 topsoil samples of Yibin,Sichuan Province,were colle... |
