Methods for Derivation of Site Specific Standard for Management of Contaminated Agricultural Soil

The action plan for soil pollution control (The Soil Ten Measures) proposes the agricultural soil to be put into three categories based on its contamination level. The unpolluted and slightly polluted soil is classified as priority protection, the mild and moderate polluted soil is classified as security utilization class and the heavy polluted soil is in the strict control category. Those categories should be judged based on the site specific soil standard. Based on the standard GB 15618-2018, the method for derivation of adverse effect critical value and safe use critical value could be a tool to facilitate the implementation of countermeasures to protect soil environmental quality, food safety and plant growth.
