Technological Innovation Progress of Risk Sources Identification and Monitoring of Sudden Environmental Pollution Accidents:(I) Risk Sources Identification Technologies and Applications

Environmental risk prevention and control and environmental risk source management is one of the important tasks of environmental management in China. In order to prevent and control major environmental pollution accidents, and to carry out efficient management of environmental risk sources and make scientific decision, the risk source identification, monitoring and management technologies for major environmental pollution accidents were developed. International experiences on environmental risk source management were summarized. Based on the principle of environmental risk source management “by type, by grade and by region”, the methods for environmental risk source classification, identification and quantitative-grading were developed. The methods could be used for environmental risk source classification on the typical chemical industrial park, mega-city and countrywide scale. A list of national key risk enterprises of petrochemical chemical industry was put forward. The environmental risk source integrated management system was developed, which could provide technical support for the key environmental risk sources supervision and the environmental risk control.
