Abstract

Abstract

The reclamation district of Lingkun Island in Wenzhou was taken as a study object in order to supply reference for rational planning of reclamation district, through determinations and risk assessments of heavy metal Cd、Cr、Cu、Zn、Mn、Ni、Pb、Hg and As in samples collected from six areas. The results showed the soils of reclamation district area were polluted by Cd and Hg，with the geoaccumulation index of Cd and Hg higher than that of other heavy metals, which contributed to the ecological risk of heavy metals in reclamation district. The contents of heavy metals in the soil of survey area were sediment reclamation district agricultural district other 4 districts. The Luminescent bacteria tests indicated the soils of sediment reclamation district belonged to medium toxicity, where the Xenopus tropicalis embryos hardly survived. Therefore, recovery methods of sediment reclamation district should be taken before the utilization and development.
