Mercury pollution detection has increased a lot since the first anniversary of the implementation of the Minamata convention

with the acceleration of China's industrialization, environment and food safety have increasingly become the primary concern of the people. As we all know, heavy metals are increasingly becoming an important factor affecting the environment and food safety. Mercury is one of the most toxic heavy metal elements in the environment. Nowadays, mercury pollution has caused huge negative effects on food, environment and human health

mercury pollution continues to intensify

Minamata convention was born in response to the call

with the development of mercury industry, mercury pollution is becoming more and more serious, and has become a worldwide problem. As we all know, the sources of mercury pollution are mainly human factors, mainly from wastewater discharged by chlor alkali, plastics, batteries, electronics and other industries, as well as waste medical devices. Because Mercury is highly volatile, strong adsorption, and difficult to be degraded, it is easy to pass through the food chain and diffuse, and finally enter the human body

the culprit of Minamata disease is organic mercury. In the mid-20th century, Minamata, Japan, was the first to suffer from serious mercury pollution. Moreover, mercury pollution incidents have also occurred in the United States, China, Brazil, etc. With the rapid development of economy, industry and human activities release a large amount of mercury into the atmosphere, and environmental mercury pollution is increasing. Mercury has been recognized as a "global pollutant"

only by actively responding to the Minamata convention, which is more suitable for international users, can we select products and equipment that are more suitable for ourselves to reduce and control mercury emissions. The Minamata Convention on mercury officially entered into force in China on August 16, 2017. China will implement a number of measures, standards and methods to minimize metal mercury pollution. In October of the same year, the first conference of the parties to the Minamata Convention on mercury was held in Geneva, Switzerland, and this meeting is a continuation of China's efforts to prevent and control mercury pollution

frequent mercury pollution control policies

increasingly standardized detection standards

China has a long history of mercury limitation. In recent years, the Ministry of environmental protection has formulated and implemented plans, technical policies, technical guidelines, pollution emission limits and monitoring method standards related to the prevention and control of heavy metal pollution, covering many links of mercury management and pollution prevention

at the national level, the use and addition of mercury in products are constantly restricted. In 2013, the Ministry of environmental protection, together with many departments, further promoted the elimination of mercury containing hygrometers, thermometers, Zhongwang's R & D and supporting capabilities, and continuously enhanced mercury containing products such as sphygmomanometers; In November 2016, the State Council issued the 13th five year plan for ecological environment protection, which clearly requires strengthening mercury pollution control and reducing the amount of mercury used per unit product of the PVC industry by 50% on the basis of 2010 by 2020. In 2017, the Minamata Convention on non conflict in mercury production put forward clear requirements for mercury control and steadily promoted mercury emission reduction in key industries

in order to curb the momentum of mercury pollution, the state has also formulated and revised a series of standards related to mercury limits and detection. Among them, GB national standard for food safety limits of pollutants in food stipulates the limits of mercury in different foods, GB 5009 national standard for food safety determination of mercury and organic mercury stipulates the detection methods of total mercury and organic mercury in food, HJ water quality determination of mercury, arsenic, selenium, bismuth and antimony atomic fluorescence method stipulates the detection methods of mercury in water quality, etc

innovative exploration of enterprises in the industry

detection and re drawing vertical lines from the central point of the horizontal center to the upper and lower bottom (plastering surface of the test piece) devices continue to emerge

mercury pollution has become a public enemy of global environmental protection, and the first step in the prevention and control of mercury pollution is detection. Atomic fluorescence spectrometer plays an important role in the detection of heavy metals because of its low detection limit, high sensitivity and strong anti-interference ability. Beijing jinsuokun has focused on atomic fluorescence technology for more than 30 years, and has done a lot of experimental exploration in reducing the memory effect of mercury. The company launched a new generation product SK Le analysis, which integrates the research results of jinsuokun company for many years, and has unique advantages in mercury detection

mercury and its compounds are highly toxic and belong to environmental heavy metal pollution elements. At present, there are various detection methods for mercury at home and abroad. Swiss Wantong also provides a comprehensive solution for the detection of heavy metal pollution of mercury. 946 portable heavy metal rapid analyzer is the latest product launched by Swiss Wantong. It is specially designed for outdoor analysis and truly realizes on-site detection

haiguang instrument has been paying attention to the progress of Minamata Convention and believes that the independent research and development of mercury meters is an important direction for haiguang company to expand its product line. After nearly two years of research and development, hga-100 mercury analyzer was launched in 2017. This instrument adopts the cold atomic absorption spectrophotometry principle in line with the standard, which can realize the direct injection measurement of solid and liquid samples, especially suitable for customers in the fields of environmental protection, food and tap water

up to now, on the first anniversary of the implementation of the Minamata convention, China has made effective progress in mercury pollution control by effectively fulfilling its obligations under the Convention. Whether it is to increase technology research and development, the introduction of standard methods, or the innovative introduction of mercury detection instruments, they have all played a good start for mercury pollution detection. Next, China will continue to strengthen the treatment of mercury pollution, which is not only the need for the development of ecological benefits in China, but also an important embodiment of national and international
