Abstract:
Soil contamination seriously poses risk to human health and ecology environment, and is a key constraint to achieving the goal of Beautiful China. Focusing on the current research of soil environmental management laws and standards at home and abroad, the paper systematically combed the development process of soil environmental protection standards for construction land in China. By constructing a standard syst[1]em framework based on soil pollution risk management and control in construction land, the classification characteristics of different typed standard documents are analyzed, and the improvement plan and development direction of standards are suggested. The results exhibit that, China has basically established a self-characteristic soil environmental management system of construction land, with the experienced support and investigated foundation of developed countries, and the environmental management standards are successively developed periods such as soil contamination control, soil quality, and soil risk management. Based on the analysis of 200%2B national, trade, and local standards, the standard document accounts for 70% of inspection methods. The number of management guidance documents for different contaminated sites is relatively balanced. Pesticides and spectrophotometry are the main pollutant testing types and detection methods, respectively. Future development tasks can be carried out from developing a risk assessment model with refined parameters and localization, formulating regional construction land soil pollution remediation standards that meet the needs of different uses, and improving risk investigation, detection and analysis, and prevention and control related technical specifications, etc. The follow-up work will continue to promote the construction of the soil environmental management system, effectively optimize and improve the in-depth soil ecological-environmental standard system, and provide powerful technical support for the ultimate success of soil contamination prevention and control.
