Soil pollution risk assessment is based on the investigation of soil pollution status, analyzing the main exposure pathways of pollutants in the soil and groundwater of the plot to the population, and assessing the carcinogenic risk or harm level of the pollutants to human health. The work content of risk assessment mainly includes hazard identification, exposure assessment, toxicity assessment, risk characterization, and calculation of soil and groundwater risk control values. Our company has rich work experience in risk assessment of risky soil pollution. It can accurately and quickly determine the pollutants concerned, identify the types of sensitive receptors, and proficiently calculate the exposure of soil and groundwater and pollutant-related parameters, so as to assess the carcinogenicity of human health Risk and hazard levels, risk control values are proposed, and pollution restoration targets are recommended.
