 Research on air pollution in Beijing Tianjin Hebei and surrounding areas: the three industries have great potential for reducing emissions.


Data map: Beijing citizens travel in the haze. Liu Guanguan, a journalist from China China News Agency The research project, called the long-term planning and research project for deepening air pollution control in Beijing, Tianjin and Hebei and the surrounding areas, was officially launched in 2015. The office of the cooperation group on air pollution prevention and control in Beijing, Tianjin Hebei and its surrounding areas was commissioned by the Beijing Environmental Protection Bureau to organize the Chinese circular Academy. According to the introduction, the study includes 11 special studies on the impact of regional pollution transmission, social and economic synergy development and structural adjustment, and the list of air pollution control projects, including the Environmental Planning Institute of the Ministry of ecological environment, Tsinghua University, Peking University, Beijing University of Technology, and Beijing city ring. The 17 research institutes, such as the seven provinces (district and city), such as the Academy of Sciences, such as the Academy of Sciences, are large in the research team and high in the unit level, representing a higher level in the research field of air pollution control in China. Chai Fahe, deputy director of the national air pollution prevention and control joint center and the chief scientist of the China Institute of environmental science, first established the list of air pollutants emission from seven provinces (regions and cities) of Beijing, Tianjin and Hebei (areas and cities) of Beijing, Tianjin and Hebei (Beijing, Tianjin and Hebei Lu Yu). The pollutants involved include inhalable particles (PM10), fine particles (PM2 .5), sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), ammonia (NH3), carbon monoxide (CO), etc., involving seven categories of pollution sources, including combustion sources, industrial sources, mobile sources, dust sources, living sources, agricultural sources, natural plant sources and so on.

Zhai Yujia, a journalist from China China News Agency According to the results of this study, although the overall regional air quality has improved, the total emissions of Beijing, Tianjin and Hebei are still large, the situation is still severe, and the pollution reduction is needed by the region. The research suggests that, in the long term, if the target of regional air quality is met, the main air pollutants should be reduced by 40%-80% on the basis of 2015 emissions. The industries with the greatest potential for emission reduction are steel, cement and petrifaction, and the three regions of Beijing, Tianjin and Hebei are controlled by 2 billion tons in the long term. The research suggests that the implementation of the atmospheric environment zoning control, the implementation of differential energy policies to reduce the total amount of coal consumption, promote regional standards and technical transformation to improve the level of fixed source pollution control, and on the basis of continuing to carry out the management and control of vehicle oil road mark, optimize the regional traffic layout and the construction of green transportation system. According to introduction, in 2017, the average annual concentration of PM2.5 in 70 cities of seven provinces and regions in Beijing, Tianjin Hebei and its surrounding areas was 55? G/m3, down 11.5% compared with 2016, and 37.2% compared to 2013 (calculated in 41 cities in 2013). The annual average concentration of PM2.5 in Beijing, Tianjin and Hebei is 64? G/m3, which is 9.9% lower than that in 2016, which is 39.6% lower than that in 2013. The average annual concentration of PM2.5 is three.
