These results suggest that air pollution levels in Beijing are very high compared with those at the two Japanese metropolises we evaluated. The diagnostic ratios of PAHs and nitrated polycyclic aromatic hydrocarbons (NPAHs) suggest that the major sources of PAHs and NPAHs in Beijing are different...
Effective abatement of air-pollution-induced health damages requires a comprehensive understanding of the changing roles of individual sources and cross-regional transport. Here, we estimate premature mortality attributable to specific source categories, precursor species, and regions within mainland China. ...
Air pollution is caused when air is contaminated with poisonous substances, particulate matter, and droplets of liquid, which damage the health of human beings and other living organisms.
This paper analyses long range fractional dependence of China pollution in four major cities, namely Beijing, Shanghai, Guangzhou and Shenzhen from September 28 of 2013 to December 12 of 2015. Unit roots hypotheses are tested by using fractional integration methods using both uncorrelated and autocorr...
Below are some facts and info on environmental pollution. WHO reports that in 2012 around 7 million people died – one in eight of total global deaths – as a result of air pollution exposure. This finding more than doubles previous estimates and confirms that air pollution is now the world...

Abid Omar, a long-time Beijing, China resident originally from Pakistan, made waves with his outdoor citizen network of AirVisual air quality monitors. The data he compiled had an important impact on his country's response to the air pollution problem. Pakistan's one-man air pollution solution...
Over the years 2015 to 2019, air pollution has declined annually by 6.9% in the average city and by 8.1% in the big cities. In early 2020, urban air pollution sharply declined in China due to the COVID-19 induced economic shutdown (He et al., 2020).1 In the first three months of...
