Hundreds of tons of mercury emissions in China face governance
Global action on mercury pollution prevention in 140 countries
Feng Xinbin, a researcher at the Institute of Geochemistry of the Chinese Academy of Sciences, said in an interview on January 11 that this year the United Nations Environment Programme will start drafting a legally binding international instrument on the prevention and control of mercury pollution, increasing mercury pollution worldwide. control. China will also actively participate in its drafting and formulation.
Feng Xinbin introduced that mercury is a global pollutant. It is transmitted through the atmosphere and is very fluid. After settling, it is further transformed into methylmercury, which poses a danger to human health and the environment. In February 2009, at the United Nations Environment Programme ministerial meeting in Nairobi, Kenya, 140 countries signed a global treaty on mercury pollution mitigation, and it was determined that in 2010, the drafting of a law on the prevention and control of mercury pollution began. The binding international instruments, including the safe storage of mercury on a global scale, reducing the supply of mercury, and reducing the mercury content in products, are planned to be completed by February 2013. The instrument is designed to address issues related to the use, release and release of mercury worldwide and is expected to become a binding regulation for mercury pollution. The Chinese government has made it clear that it will actively participate in its drafting and formulation.
China is a major producer and consumer of mercury and one of the major emitters of mercury. Coal-fired power plants, metal smelting, cement industry, chlor-alkali industry, and mercury mines are the major sources of mercury pollution in China. According to estimates by Feng Xinbin, China's annual mercury emissions range from 500 to 800 tons. Since the basic census work is not yet in depth and basic information is lacking, this figure has great uncertainty. As the international upper limit of mercury is increasing, in recent years Chinese scientists have strengthened their research on the prevention and control of mercury pollution, key projects of the National Natural Science Foundation of China, the "863" project of the Ministry of Science and Technology, key orientation projects of the Knowledge Innovation Project of the Chinese Academy of Sciences, and international cooperation projects. Both the Natural Science Foundation of China and the Natural Science Foundation have provided funding.
Feng Xinbin also pointed out that the prevention and control of mercury pollution in China is in its infancy. There is still a lot of work to be done in the census of emission sources, the treatment technology of pollutants, the formulation of relevant technical standards, and the laws and regulations for the prevention and control of pollution. At present, there are few regulations related to the direct control of mercury emissions. Europe and North America have some application technologies to prevent and control mercury pollution. However, because there are no well-targeted regulations and technical standards, the promotion of such technologies is still difficult.
