Health Risk Assessment and Quantitative Calculation of Typical Cr Contaminated Sites

摘要

Select the former site of a chemical factory in Chongqing, China as the typical Cr contaminated site. According to "Technical guidelines for risk assessment of contaminated sites"and "Standard of Soil Quality Assessment for Exhibition Sites(Interim)" (HJ-350-2007), this paper conducts health risk assessment for the site, and provide a basis for contaminated soil remediation. At the same time, according to the contaminated condition, used the Golden Software Surfer 8 to draw the boundary of contaminated soils and thus calculate the volume of contaminated soil. By estimation the volume is about 3122.3 m~3, which provide detailed data for the later remediation engineering.
