UK, Chinese scientists confirm Beijing's air quality has improved significantly - China.org.cn

Beijing's air quality has improved dramatically in the last few years owing to the emission reductions following the implementation of clean air actions, according to a latest report released by a group of leading British and Chinese scientists.

A team of more than 150 scientists have spent five years conducting one of the largest air pollution field campaigns in Beijing -- generating new insight into air pollution and human health using novel observational and modelling tools, said a press statement published Tuesday on the website of the University of Birmingham.

The scientists have found that sources of key air pollutants in the city center, including fine particles, volatile organic compounds (VOC), and black carbon are much lower than predicted, but concentrations were still relatively high in 2016 and 2017, indicating they were created outside the city center.
