LONDON FOG COULD SAVE BEIJING

Recently, an team of scientists discovered why the London fog of 1952 was so fatal. Smog becomes hazardous, when sulphur dioxide is converted into sulphate, which forms part of tiny air particles. In 1952, the conversion was boosted by NO from the burning of coal. So, in the future, NO threshold values could prevent China’s fog from becoming as fatal as London's.

Smog in the Chinese city of Harbin forces people to wear masks.
