| Taking the land from chemical plants removal as an example, three kinds of land use planning such as residential land, commercial land and elevated construction land were compared in human health risks. Results showed that it was recommended the land was planned for elevated construction land if the human health risk level was at around 10-5, a relatively low risk, and the risks were mainly in the surface soil and micro confined groundwater. According to the planning use, the soil and groundwater risk controlling targets, in the soil of 0 m～1.5 m deep underground, the content of benzene and hexachlorobutadiene were 7.72 mg/kg and 38.5 mg/kg, respectively; in groundwater, the content of benzene and hexachlorobutadiene were 355 mg/L and 53.5 mg/L, respectively. |
