From Sydney Morning Herald:
China will shift a giant steel mill that is a big source of air pollution out of its capital city before it hosts the Olympic Games in three years.But as it shuts down one kind of atmospheric pollution, Beijing has been revealed as centre of the world’s most dense concentration of another.
New satellite images released by the European Space Agency show Beijing and the surrounding region of north-east China are the world’s worst area for nitrogen dioxide pollution, produced by poorly filtered vehicle exhausts.
