All Beijing Gas Stations to be Refrofitted

All gas stations in Beijing will be updated to prevent petroleum vaporization from causing smog and help improve air quality before the 2008 Olympic Games.

Sarah Liao Sau-tung said the municipal government has started equipping about 1,400 gas stations with vapor traps and recovery devices on which work is expected to be completed by the end of next May.

Photochemical smog, which Beijing often suffers from, forms when photons of sunlight hit molecules of different kinds of pollutants in the atmosphere, creating an atmospheric condition that produces eye irritation and poor visibility. It smells bad and makes it hard for people to breathe.
