More Natural Dust Improves Air Quality in Eastern China
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. That’s because dust plays an important role in determining air temperature and thereby promotes winds to blow away man-made pollution. Less dust means the air stagnates, with man-made pollution becoming more concentrated and sticking around longer.
