(Shang- hai Academy of Environmental Sciences .Shanghai 200233) Abstract: It is significant to establish soil environmental quality evaluation standard system in line with Shang- hai soil characteristic for the risk assessment and remediation of contaminated urban soil in Shanghai. The contamina- ted soil standard systems of developed countries and China were introduced and discussed. Based on the amendment of a Chinese standard ,Soil Quality Assessment for Exhibition Sites (HJ/T 350-2007) , some suggestions were proposed for the development of soil quality evaluation standard system. For the setting of soil guideline values ,the sensitive re- ceptors ,types of land use ,pollutants and exposure pathways could be selected according to city plan features and soil pollution background ,the remediation technologies ,patterns (in-situ or ex-situ) and soil disposal methods should be also considered during the development of soil remediation standard. At the same time ,it is suggested that the instru- mental analysis ability should be advanced and the relevant laws and regulations should be bui 1t and strengthen so as to ensure the effective application of standard system.
