How dirty is the air in China?
The annual average concentration of fine particulate matter (PM2. 5) across China was 57 micrograms per metre cubed in 2017, nearly six times what the World Health Organisation deems to be acceptable limits. Poor outdoor air quality results in over 1 million deaths across China each year.
Is China losing money on Olympics?
