T/LNSES 002-2022 Guidelines for practical quantification of environmental damage assessment of soil contaminated by heavy metals in sites with pollution

Scope

Main technical content: This guide is applicable to the physical quantification work of soil ecological environment, human health, and property damage appraisal and evaluation caused by heavy metal pollution at polluted sites due to environmental pollution behaviors. This guide stipulates the principles, processes, methods, and technical requirements for the physical quantification of soil environmental damage appraisal and evaluation at heavy metal pollution sites. Specifically, it includes: (1) the scope of application of the guide; (2) normative reference documents; (3) definitions of 7 terms; (4) principles and workflow of physical quantification; (5) requirements for collecting physical quantification information; (6) methods of confirming baselines; (7) methods of physical quantification for different types of damage; (8) analysis of the recoverability of the environment at the damaged site; (9) methods of formulating restoration plans; (10) methods of quantifying damage during the restoration period; (11) principles for dividing recoverable and non-recoverable parts of the damage; (12) uncertainty analysis of the results; and (13) requirements for preparing physical quantification reports (opinions).
