T/LNSES 001-2023 Site Soil Environmental Damage Investigation Technical Guide: Soil Worm Investigation and Evaluation

Scope

Main technical content: This document specifies the principles, methods, and main contents of the investigation of soil environmental damage in sites - soil nematode investigation. It is applicable to the identification and assessment of shallow-layer soil environmental damage - biological and ecological environmental damage, and is not limited by soil type. The soil nematode investigation in this document solves the tediousness of measuring pollutants and other indicators in traditional damage investigations, and evaluates and identifies pollution damage from a biological perspective, reflecting the damage to the ecological environment caused by site pollution. This document includes the main text, two normative appendices (Appendix A and Appendix B), and two informative appendices (Appendix C and Appendix D). Among them, the main text is divided into eleven chapters, including the scope of application of this document, normative reference documents, terms and definitions, basic principles, materials, reagents, and equipment, soil nematode investigation methods, soil nematode community evaluation methods, soil nematode structure and functional integrity evaluation methods, soil nematode data processing and analysis, quality control, and report preparation. The normative appendix A is the record table of habitat elements in the investigation site, and the normative appendix B is the record table of sample sites and sample plots. The informative appendix C is the principle and advantages of soil nematode community evaluation methods, and the informative appendix D is the literature for soil nematode classification retrieval
