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.
