The Beijing-Tianjin area will examine PM2.5 and set up an office and monitor the pollution density change in real time
It is reported ' The intersection of reporter and horsepower) Beijing and Wuqing between the Tianjin set up one the intersection of atmospheric environment and comprehensive monitoring station, monitor density of pollutant in the atmosphere such as ozone, PM2.5 in real time, study its transmission and transformation in the air. Weather bureau knew from Tianjin yesterday the reporter, the weather bureau of Tianjin cooperated with environmental research institute of China, set up the comprehensive monitoring system of regional atmospheric environment of first Beijing and Tianjin. Build the comprehensive monitoring station of the environment to it is introduced, with the economic development and acceleration of urbanized process of Beijing and Tianjin area between Beijing and Tianjin, atmospheric environmental pollution is serious gradually too, pollution such as gray haze, ozone have already influenced the people's lives, health in Beijing and Tianjin area. The Tianjin relevant person in charge of weather bureau introduces, this both sides will build together the comprehensive monitoring station of a regional atmospheric environment in Tianjin Wuqing district, and build up it into leading in the world, domestic and first-class atmospheric scientific research base, offer science for atmospheric environmental improvement decision in the countries and regions to support. As to why choose Wuqing build a station, the person in charge explain Wuqing district locate Beijing and between the Tianjin, about 70 kilometers from Beijing, 25 kilometers from Tianjin urban area, at the Beijing-Tianjin air pollutant transmits the passway. Carry on atmospheric scientific research here, has offered the good geographical position condition for the transport characteristic of the pollutant while catching Beijing and Tianjin. Will appraise the comprehensive monitoring station of atmospheric environment of Wuqing of impact on health of the detailed particulate matter and monitor environment and meteorological phenomena synthetically, not only include the general air pollutant, also include ozone relatively paid attention to at present and thin particulate matter, superfine particulate matter two times,etc.. Monitor and analyze the cause of regional air pollution of Beijing and Tianjin, and the pollutant is in transmission between two cities, forming of secondary pollution,etc.. Meanwhile, the monitoring system will also monitor and predict the fog haze weather of the Beijing-Tianjin area. It can observe steam field, temperature field, radiation of the atmosphere,etc.. When it presents low visibility, analyze its change, thus improve calamity its forecast ability such as the fog haze. Will also set up the index system that impacts on health of atmospheric composition such as ozone, particulate matter, sulfur dioxide,etc. will be appraised with monitoring system, assess the impact on health of pollutant. In addition, the system will also monitor the air pollutant in Beijing and Tianjin area in real time, and release and predict prewarning, prevent serious atmospheric contamination accident. Take the pertinence measure to the contamination accident happening ahead of time, avoid or lighten pollution danger. The noun explains PM2.5 means the diameter is less than or equal to detailed particulate matter of 2.5 microns in the atmosphere, also calling can enter the lung particulate matter. Its diameter is still less than 1/20 of people's hair silk thickness. Though there is little content in it is in the atmosphere, it has important influence on air quality and visibility,etc.. A large number of poisonous, harmful substances contained of its, there is greater influence on also health. PM10 means the diameter is also called the inhalable particles or floating dust in particulate matter of under 10 microns. Measure many suits of apparatus monitor weather station, district of Wuqing, install have to observe apparatus online particulate matter at present in real time, can observe the density of PM2.5 and PM10 online. According to the scheme of cooperating, this year and next year, the monitoring station will set up apparatuses such as PM10 online quality density analysis instrument, PM2.5 black charcoal aerosol analysis instrument, PM2.5 membrane sampling device,etc.. Real-time to monitor it in the regional atmosphere in Beijing and Tianjin online, the changes and floating tendencies of PM2.5 quality density. In 2013, the monitoring station will set up PM2.5 high flux sampling device, PM2.5 online ion apparatuses such as the analysis instrument,etc., improve the analytical capacity of supervision on PM2.5. The background PM2.5 plans to be regular to monitor On November 16, the department in environment protecting mode notifies, " surrounding air quality criteria " solicits the opinion publicly for the second time of revised edition, every dispute PM2.5, ozone (the density of 8 hours) Include in the regular air quality evaluation, and tightened up PM10, nitrogen oxide,etc. standard limit. This is that our country makes PM2.5 standard for the first time too. And then, some cities of Wuhan, Harbin, Shandong say immediately, will monitor PM2.5 and and disclose the data.
