摘要
Abstract
Nowadays,there are many heavy metal pollution problems at the locations of most industrial enterprises.A nickel contaminated site was used to carry out a repair research.According to the national guideline,the risk control value of this site is 94,mg/kg.About 24,000,cubic meters of soil needs to be remediated.However,the guideline is quite conservative,so the calculation of risk control value is conservative,too.If the calculated objective control value on the spot is taken as the target value of remediation,more earth needs to be remediated.Through the human bioaccessibility experi-ment,the risk control value was up to 491,mg/kg and the earthwork was reduced to 3,000 cubic meters.Verifying the risk control value can not only avoid harm to human health,but also provide a reasonable remediation control value to help re-duce the cost of remediation.关键词
