WORKERS were today urged to help achieve cleaner air by walking or cycling to the office.
It comes as new figures showed "dangerous" levels of toxic pollutants in the UK.
The Chartered Society of Physiotherapy said much of the country was "choked" by filthy fumes from traffic and industry.
The Society will call on the TUC Congress in Brighton to lobby the Government to show greater commitment to achieving cleaner air.
It said unions should encourage workers to cut fumes.
The Society published a league table of high pollution areas, including Bradford, Port Talbot, Leeds, Bury, Stockton on Tees and parts of London.
Grahame Pope, of the Society, said:
"No parent wants to see the children off to school in a face mask, but unless the Government, car manufacturers and drivers do their bit to improve air quality, this is a possibility."
