Application Summary AI generated
This standard specifies technical requirements for immobilization remediation of heavy metal contamination in paddy fields, focusing on the application of passivating agents to reduce metal bioavailability in soil. It is used by agricultural and environmental agencies in China for in-situ remediation of rice paddies contaminated with cadmium, lead, or other heavy metals. The standard applies to field operations where immobilization materials are incorporated into soil to limit heavy metal uptake by rice plants.
