According to the _South China Morning_ _Post_, a recent study of 74 cities analyzed some 3.03 million deaths recorded in 2013, and found that 31.8% of them could be linked to smog. The study, carried out by researchers at China’s Nanjing University, found that the air was most toxic in the cities of Baoding, Shijiazhuang and Handan, each reporting more than 30,000 deaths in 2013 that could be linked to pollution. It does not appear that the situation has markedly improved in the years since. Last Friday, Beijing issued a “red alert” warning because of a blanket of thick smog shrouding the capital city and a large swath of northern China, affecting nearly half a billion people. With pollution levels reaching about 500 PM2.5 particles per cubic meter — the WHO ranks safe levels as under 25 — the so-called airpocalypse, has sent tens of thousands fleeing to southern parts of the country, where the air is cleaner. > [](https://twitter.com/GreenpeaceEAsia/status/811130151652114433) Hospitals have been crowded with patients suffering respiratory problems, whole highways have been shut down, and hundreds of flights grounded. Classes were also cancelled — although in one case [exams were not](http://time.com/4616344/china-smog-pollution-henan-students-exams/ "undefined"). Shocking images spread across the Internet showing schoolchildren seated outside wearing jackets and face masks, huddled over desks to take a test in gray, toxic gloom. > [](https://twitter.com/ChuBailiang/status/811354532168929281) The _Post_ reports that the new findings from Nanjing support previous research; the paper says that the International Energy Agency published a report in June claiming that air pollution has trimmed some 25% off life expectancy in China, while a study co-authored by researchers at three renowned universities determined that people in China’s north could lose an average of 5.5 years of life due to smog. **_Read more:_** [_Beijing’s Air Pollution is Frightening. This Video Shows Just How Bad It Gets_](http://time.com/4607605/china-beijing-pollution-smog-environment-video/ "undefined") China’s National Energy Administration reportedly said Wednesday that it will enact measures such as limiting high-pollution fuel emissions and [launching a satellite carbon-dioxide monitor](http://www.reuters.com/article/us-climatechange-summit-china-satellite-idUSKBN14B00U "undefined") to mitigate the problem, but many in the country’s vast ultra-industrial cities remain skeptical. Greenpeace has warned that the economy must urgently be made less dependent on polluting forms of energy and that people living in cold northern climates should be given alternatives to coal, which causes much of the smog. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4617295/china-smog-smoking-environment-air-pollution/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4617295/china-smog-smoking-environment-air-pollution/"},"headline":"China's Smog Is as Deadly as Smoking, New Research Claims","datePublished":"2016-12-23T06:44:21.000Z","dateModified":"2026-02-23T02:27:12.171Z","description":"Current severe smog in northern China is affecting nearly half a billion people","url":"https://time.com/4617295/china-smog-smoking-environment-air-pollution/","keywords":["China"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd6d2d44d22b28ecc/6988b3e5f887dcb874e9891e/gettyimages-630285912.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Feliz Solomon","jobTitle":null,"url":"https://time.com/author/feliz-solomon/"}],"articleSection":"World","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd6d2d44d22b28ecc/6988b3e5f887dcb874e9891e/gettyimages-630285912.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Heavy Smog Hit North China","caption":"Heavy Smog Hit North China","creditText":"VCG via Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/world/","name":"World"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4617295/china-smog-smoking-environment-air-pollution/","name":"China's Smog Is as Deadly as Smoking, New Research Claims"}}]}] ```
