T/LNSES 002-2025 Safe utilization technical specifications for contaminated soil of heavy metals in construction land disposal
Basic Information
Scope
Main technical content: This document specifies the safe utilization methods for soils contaminated by heavy metals after remediation, as well as the technical requirements for controlling heavy metal pollutants under various safe utilization methods. This document applies to soils contaminated by heavy metals in construction land, but not to soils contaminated by heavy metals in agricultural land. It does not apply to volatile or semi-volatile organic polluted soils, radioactive polluted soils, or soils contaminated by pathogenic organisms. The heavy metal pollutants covered by this document mainly include: lead, cadmium, arsenic, zinc, chromium, copper, and nickel. For the safe utilization of soils contaminated by heavy metals and other types of pollutants after remediation, the technical requirements for controlling other types of pollutants shall refer to other standards and specifications. For the safe utilization of soils contaminated by heavy metals and organic pollutants after remediation, the technical requirements for controlling heavy metal pollutants may refer to this technical specification.
