On May 18, Xiling Gorge of the Yangtze River after rain, with high gorges and flat lakes, green mountains and green waters, and swirling clouds, formed a beautiful natural ecological beauty. Mercury pollution is becoming a serious global pollution, especially coal-fired power plants account for a large proportion. This paper first sorted out the mercury pollution situation at that time and the monitoring requirements of various governments, and introduced the calibrators, catalytic conversion methods, measurement methods, key points and precautions in the system planning of the mercury continuous emission monitoring system CEMS. Polaris Atmosphere News: A few days ago, Henan Province issued the operation plan for Henan Province to promote industrial restructuring and win the battle against pollution. According to the requirements of the plan, by the end of 2019, the Ministry of Steel Ecological Environment, the Ministry of Human Resources and Social Security, the All China Federation of Trade Unions, the Central Committee of the Communist Youth League, the All China Women's Federation, and the General Administration of Shopping Mall Supervision and Management of the whole province recently issued the Notice on Holding the Second National Ecological Environment Monitoring Professional Skills Staff Battle. The relevant person in charge of the Ecological Environment Monitoring Department of the Ministry of Ecology and Environment answered the reporter's questions on the relevant contents.

Continuously improve the scientific level of monitoring to ensure that the monitoring data are "true, accurate and complete"

Why is it necessary to carry out a national exchange of professional and skilled personnel in ecological environment monitoring?

A: In 2010, the former Ministry of Environmental Protection, the Ministry of Human Resources and Social Security and the All China Federation of Trade Unions jointly held the first major confrontation activity of the list. The VOCs online monitoring system has achieved remarkable results. In the national ecological environment monitoring system, an upsurge of learning professional theories and studying business skills has been set off, which has strongly promoted the progress of the skill level of the ecological environment monitoring force.  

（1） Carrying out the big fight is a powerful way to improve the level of ecological environment monitoring skills and support ability. Ecological environment monitoring is an important foundation for ecological environment management and ecological civilization construction. Carrying out a major confrontation and building a dense atmosphere of "comparison, learning, catching up and surpassing" will help to improve the overall skill level of ecological environment monitoring, pool the monitoring efforts of all parties, guide the development direction of monitoring skills, consolidate the fundamental role of ecological environment monitoring as the "pillar" of ecological environment protection, and provide strong support for the fight against pollution and ecological environment protection.

（2） It is an important practice to carry out a major confrontation activity to promote the energy of craftsmen in the field of ecological environment monitoring. Data quality is the "lifeline" of ecological environment monitoring. Promoting the pursuit of extreme, rigorous and accurate "craftsman energy" is an important manifestation of the credibility and competitiveness of ecological environment monitoring. After carrying out a major confrontation activity, we advocated scientific monitoring, integrity monitoring, meticulous work, and seeking outstanding professional culture. In accordance with the work requirements of "strict, true, detailed, practical, and fast", we continued to improve the scientific, standardized, and standardized level of ecological environment monitoring, and ensure that the monitoring data is "true, accurate, and complete.".

（3） It is an important measure to build an iron army vanguard of ecological and environmental protection to carry out major confrontation activities.   Through the big battle activity, we strengthened the thinking, morality, skills, affairs and cultural quality of the professional skilled personnel in ecological environment monitoring, took the family, national, people and work feelings as the thinking guidance and action support, strengthened the faith and ambition, and provided a strong organization and thinking guarantee for the fight against pollution.

To this end, the Ministry of Ecology and Environment, together with the Ministry of Human Resources and Social Security, the All China Federation of Trade Unions, the Central Committee of the Communist Youth League, the All China Women's Federation and the General Administration of Shopping Mall Supervision and Administration, jointly held the second session of the exchange of professional and skilled personnel in ecological environment monitoring.

Open the door to fight, combine peacetime and wartime, conclude the fight and make joint efforts

What are the main contents and ways of the big confrontation?

A: This year's major confrontation activities are divided into ecological environment monitoring and radiation monitoring. The contents of the induction and confrontation include the monitoring skills of environmental elements such as surface water, groundwater, ocean, atmosphere, greenhouse gas, sound, solid waste, soil, ecology (including biology), etc. The contents of the special confrontation include the environmental monitoring skills of ionizing radiation and electromagnetic radiation, and the theoretical knowledge, instrument analysis, quality control skills, evaluation skills, and induction and analysis abilities of the contestants.

This year's event is divided into two stages: provincial (three military) competition and national final. The provincial (three military) games take monitoring (detection) organizations as the unit to encourage the ecological environment department, other departments and various monitoring (detection) organizations at all levels of society to actively register. The national finals were organized by the provinces (districts and cities), Xinjiang Production and Construction Corps, and the Military Facilities Construction Bureau of the Military Commission Logistics Assurance Department. Each team consists of one leader, five players in the general competition and four players in the special competition. In principle, the players are composed of the winners of the provincial (three service) competition. The national final consists of two parts: theoretical knowledge examination and on-site operation competition. The theoretical knowledge examination is conducted in a closed book manner, and the on-site operation competition is conducted in groups. The theoretical knowledge examination and on-site operation competition shall calculate the total individual results according to the score proportion of 4:6, and the total collective results of the concluded and special competitions shall be calculated separately according to the total individual results of the players participating in the national finals.

What are the main features of this year's big confrontation?

A: First, adhere to the open door confrontation and encourage various ecological environment monitoring (detection) organizations at all levels to participate widely. All kinds of organizations with CMA qualification and engaged in ecological environment monitoring (detection) can participate in the competition to ensure the universality and universality of this big fight.

The second is to emphasize inductive ability, and investigate the monitoring skills, evaluation skills and inductive analysis skills of the basic environmental elements of ecological environment quality. Surrounding the fine management of the environment and supporting the fight against pollution, we conducted a systematic competition on the monitoring methods and technical specifications of various environmental elements such as atmosphere, surface water, groundwater, ocean, soil, nuclear and radiation, greenhouse gases, noise, and emergency monitoring of environmental emergencies.

Third, pay attention to the combination of peacetime and wartime, and outstanding check on daily monitoring work and practical operation ability. It not only pays attention to the results of the confrontation, but also pays more attention to the ability of the competition organization, the operation of the quality management system and the integrity; It not only pays attention to theoretical knowledge examination, but also pays more attention to on-site operation skills.

Fourth, adhere to fairness and equity, combine the current situation of ecological environment monitoring and management needs, make scientific propositions, and refine the evaluation criteria and procedures. Scientifically determine the monitoring confrontation items, refine the determination and scoring criteria of each link of the theoretical knowledge examination and on-site operation competition, strictly implement the confidentiality requirements, and establish a supervision committee to supervise the whole process of the major confrontation activities, so as to ensure the fairness and fairness of the confrontation competition.

What is the field operation competition? What are the considerations for the set items?

Answer: 4 field operation competition items are summarized, including permanganate index in water (volumetric method), hexavalent chromium in water (photometric method), volatile organic compounds in air (portable gas chromatography-mass spectrometry) and pH in soil (potentiometric method) γ The quantitative measurement of radionuclide activity, radioactive surface contamination and uranium in water are four on-site operation competitions.
