Beijing Says Its Air Pollution Improved During the First Half of 2015

Beijing's municipal government says air pollution in the capital improved during the first six months of 2015.
It said the concentration of tiny airborne particles that are harmful to human health — dropped by 15.2 percent from a year earlier.
However, that level remains higher than the 10 micrograms per cubic meter average considered safe by the World Health Organization.
The city government said the amounts of sulfur dioxide, nitrogen dioxide and PM 10 particles also decreased.
