2013 Eastern China smog : ウィキペディア英語版 | 2013 Eastern China smog
The 2013 Eastern China smog was a severe air pollution episode that affected East China, including all or parts of the municipalities of Shanghai and Tianjin, and the provinces of Hebei, Shandong, Jiangsu, Anhui, Henan, and Zhejiang, during December 2013. A lack of cold air flow, combined with slow-moving air masses carrying industrial emissions, collected airborne pollutants to form a thick layer of smog over the region. Levels of PM2.5 particulate matter averaged over 150 micrograms per cubic metre; in some areas, they were 300 to 500 micrograms per cubic metre. It is one of the worst bouts of air pollution in the area, cutting visibility and causing major disruption in transportation and daily activities. Airports, highways, and schools were closed. ==Background== On January 2013, China experiences massive fog and haze outbreak affecting about 600 million people and covering seventeen provinces, municipalities and autonomous regions, a fourth of the China's territory. On 12 September 2013, the State Council announced the "Air Pollution Prevention Plan". China limited the fine particulate matter level, and the Chinese government officials' assessment index included improving the environment for the first time. On 4 November 2013, Chinese Academy of Social Sciences and China Meteorological Administration jointly released "Green Paper on Climate Change: Addressing Climate Change (2013)". It states that the fog and smog in China increased in the past 50 years with the number of fog days significantly reduced, while that of the smog days are significantly increasing with the phenomenon of persisting smog days. The fastest growing fog and smog days occurred in the Pearl and Yangtze River Delta regions, which are the most industrialized areas. The report also indicated that the main reason of increased fog and smog days is the yearly increase in fossil fuel consumption in China. The report calls for urgent implementation of regional joint prevention and control measures to effectively solve the air pollution crisis.
