In a recent study by Greenpeace, over 350 of China’s cities did not meet the standard for air quality set by the World Health Organization.
Particulate matter (PM2.5) can penetrate deep into the lungs, and while many Chinese cities have lowered the levels in their air, Greenpeace reported that the national average was 50.2 parts per cubic meter – far higher than the recommended 10 parts per cubic meter.
This level showed a 10% from the previous year, though levels are still dangerously. Beijing, for the first time in history, issued two “red alert” warnings in December due to the toxicity of the air.
PM2.5 is released into the air as a result of coal burning and motor vehicles.
