摘要:
汞是一种能长期存在于环境且具有全球迁移性的污染物.汞污染防治是一个复杂的系统工程,涉及多部门、多领域、多行业,国家需要在政策、管理和技术等方面采取综合的战略措施推进汞污染防治.本文基于汞污染的环境和社会影响,分析了中国汞污染的来源、成因并评估了中国汞管理体系,结合中国参加全球汞公约谈判的特定背景,识别出汞污染防控的优先行业,包括汞的无意排放优先控制行业:燃煤、有色金属冶炼、汞矿开采和含汞废物处理;汞的有意使用优先控制行业:电石法聚氯乙烯生产,医疗产品、荧光灯和电池生产.本文也进一步提出了汞污染控制技术路径,包括构建汞风险管理和识别平台、完善汞管理体系、加强环境技术研发、推进绿色转型、保护环境和公众健康等.

Abstract:
Mercury is an important environmental contaminant that is persistent in the environment and can be transported globally. Mercury pollution prevention and control is a complex process, involving a wide range of sectors, fields and industries, and a slight move in one area may affect the whole situation profoundly in China. Therefore, comprehensive strategies in terms of policy, management and technology are needed at the national level for mercury prevention and control. In this paper, based on analysis of the environmental and social impact of mercury pollution, its sources and cause as well as the regulatory system for mercury pollution prevention and control, while taking into consideration the specific background of global mercury convention negotiations participated in by China, we proposed the following priorities for mercury pollution prevention and control: unintentional release sources such as coal burning, non-ferrous metal smelting, mercury mining and disposal of mercury-containing wastes; and intentional use such as PVC production using the calcium carbide process, production of medical appliances, fluorescent lamps and batteries. Furthermore, the technical roadmap was suggested herein including a sound mercury information platform for risk identification and management, establishment of China's management and regulatory regimes for mercury, research and development of environmental technologies, promotion of green transformations, protection of the public health and environment, etc.
