3个涉重金属污染防治国家重点研发计划项目启动实施

Core Viewpoint - The Guangxi region has made significant progress in heavy metal pollution prevention and control, with the launch of three national key research and development projects aimed at addressing soil and groundwater contamination in karst areas [1][2][3] Group 1: Project Initiatives - Three national key R&D projects have been initiated in Nanning, focusing on integrated technology and demonstration for heavy metal pollution prevention in Guangxi's karst areas [1] - The projects are led by research institutions including Sun Yat-sen University, Central South University, and the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences [1] Group 2: Specific Focus Areas - The "Comprehensive Governance of Air, Soil, and Groundwater Pollution" project aims to address the inadequate prevention of soil and groundwater pollution in Guangxi's karst metal mining areas through heavy metal tracing, risk assessment, and the development of pollution control materials and technologies [2] - The "Protection and Restoration of Typical Fragile Ecosystems" project focuses on mitigating the risks of heavy metal migration due to strong permeability and erosion in karst landscapes by employing geomorphological reshaping, soil reconstruction, and vegetation restoration [2] - The "Key Technologies and Equipment for Circular Economy" project targets the historical legacy of solid waste in resource-rich areas, addressing the reduction of heavy metal solid waste at the source and ensuring safe disposal and risk management of historical heavy metal waste [2] Group 3: Strategic Implementation - The Ministry of Ecology and Environment and the Ministry of Science and Technology have designed a systematic top-level framework for the three projects, emphasizing the application of technology in the Hechi region of Guangxi [3] - The implementation of these projects will focus on problem-oriented approaches, strengthening system integration, and creating a comprehensive technical solution package for heavy metal pollution control [3] - The goal is to transform technological investments into environmental, economic, and social benefits through the development of low-cost, low-disturbance pollution control models that are replicable and scalable [3]
