More natural dust in the air improves air quality in eastern China
More natural dust air quality eastern China
2017/7/20
Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study published May 11 in Nature Communications.Yes, you read that correctly: When...
This paper proposes a method of valuing air quality based on differences in
wages among cities. Using an urban location model it is shown that the supply of
labor to any city increases with the real...
