Recently, by I The group standard “Specification for the Investigation and Assessment of Heavy Metals in River and Lake Sediments,” edited by the institute. The standard has been approved without issues. Experts organized by the Geological Society of China Review. This standard, for the first time, … Technical requirements, investigation and evaluation procedures, assessment factors, assessment methods, and results for heavy metal surveys of river and lake sediments. and other content to do Detailed regulations have been issued. 。
This time Group Standard review, conducted by Development Research Center of the China Geological Survey , China Building Materials Geological Exploration Center, China Metallurgical Geology Bureau 、 China National Bureau of Coal Geology 、 Shandong University of Architecture, Shandong Provincial Center for Territorial Spatial Ecological Restoration A review panel composed of renowned industry experts from multiple organizations. ， Adopt offline + Online format , from of the technical document In terms of normativity, innovativeness, and applicability, among others was conducted Review and propose revisions. 。 After rigorous evaluation, the expert panel It was unanimously agreed that the standard is well-founded. 、 Procedural Standards 、 Solid foundation ， The content is scientifically comprehensive. 、 It is well-organized, aligned with actual production practices, and highly instructive and practical. Ultimately, following deliberation and a unanimous vote by the expert panel, the review was approved.
Sediments are an essential component of aquatic ecosystems and play a crucial role in the geochemical cycling of heavy metals. In rivers, 90% The aforementioned heavy metals accumulate in the sediment through chemical adsorption and physical precipitation, and the resulting heavy-metal contamination of the sediment severely impacts… done Human survival and development Most needed of available freshwater resources. Heavy metal contamination remediation in sediment, as an ecological… of environmental construction An important link, For many years, there has been a lack of standardized technical criteria for comprehensive surveys.
To this end, our hospital In summarizing recent years Investigation of Heavy Metal Contamination in Sediments Based on the research, after years of multi-site trials and validation, the “…” has been formulated. Standard for the Investigation and Assessment of Heavy Metals in River and Lake Sediments 》， It has filled a gap in the field of domestic heavy-metal surveys of sediment, and will… Helps to Investigation and Assessment of Heavy Metals in River and Lake Sediments More standardized, intensive, and systematic, in support of… Enhancement of Regional Water Environmental Quality and Ecological Security It is of great significance.
