A dense wave of smog began in Northeast China, especially in major cities including Harbin, Changchun and Shenyang, as well as the surrounding Heilongjiang, Jilin, and Liaoning provinces on 20 October 2013. Unseasonably warm temperatures with very little wind across northeastern China coincided with the initiation of Northeast China's coal-powered municipal heating system. Record densities of fine particulates were measured in the city. In Changchun, air pollution recorded at an all-time high and the levels of PM2.5 particulate matter rose to 845 micrograms per cubic metre on 22 October 2013.

  • 2013年中国东北雾霾事件是指起始于2013年10月20日，也就是哈尔滨市的年度冬季燃煤取暖系统开启的第二天，以中国东北地区(滿洲)哈尔滨为中心，和吉林省、黑龙江省、辽宁省在内的地区发生的大规模雾霾污染。由于东北地区普遍燃烧质量低劣却廉价的褐煤取暖，大量烟尘因此直接排到空中，是本次污染事件的主因。东北地区大部均被浓密的雾霾覆盖。在哈尔滨市，PM2.5的日度平均值一度达到每立方米1000微克，超出世界卫生组织安全标准40多倍，甚至比北京还要严重。能见度大幅下降，机场被迫关闭，两千多所学校停课。雾霾也导致黑龙江省境内多条高速公路被迫关闭。10月22日至23日，东北地区仍然被雾霾覆盖，PM2.5平均浓度保持在每立方米200毫克以上。在吉林省省会长春市，10月22日22时的PM2.5的浓度达到63年来的历史峰值每立方米845微克，空气质量实时指数超过500。 (zh)

  • A dense wave of smog began in Northeast China, especially in major cities including Harbin, Changchun and Shenyang, as well as the surrounding Heilongjiang, Jilin, and Liaoning provinces on 20 October 2013. Unseasonably warm temperatures with very little wind across northeastern China coincided with the initiation of Northeast China's coal-powered municipal heating system. Record densities of fine particulates were measured in the city. In Harbin, the levels of PM2.5 particulate matter rose to 1,000 micrograms per cubic metre, worse than Beijing's historic highs. Visibility dropped to 50 metres (160 ft) and authorities grounded flights and closed more than 2,000 schools. In Changchun, air pollution recorded at an all-time high and the levels of PM2.5 particulate matter rose to 845 micrograms per cubic metre on 22 October 2013. The smog eased on 25 October 2013 and had completely dissipated by the 28th due to a cold front that had moved in from Russia. (en)
