Description :
The AA. investigated the soil pH, bulk density, nutrient content and the concentrations of Cr and Pb in the 4 main green space types, namely park green (PARK), street green (STREET), attached green space (ATTACH) and protective green (PROT) in the built-up area of Anji (northwest of Zhejiang Province). Owing to past use of leaded petrol, the soils of the 4 green space types have been polluted by Pb in Anji, especially in the STREET and PROT sites. As an eco-county, Anji needs to adapt a soil replacement method and a biological treatment technology to reduce soil Pb pollution to create a favorable environment for the residents of the area. The AA. suggest that soil quality indicators should be brought into the assessment criteria for eco-country establishment in China.
