HC Deb 11 June 1992 vol 209 cc265-6W
Mrs. Prentice

To ask the Secretary of State for the Environment what has been the increase in nitrous dioxide emissions in the past five years in London; and whether there will be official Government warnings issued or advice proffered to Londoners to minimise health risks.

Mr. Maclean

Total United Kingdom emissions of oxides of nitrogen from motor vehicles—the principal source—are estimated to have risen by 38 per cent. between 1986 and 1991. The increase is likely to have been similar in the London area. Advice on the health implications of episodes of high nitrogen dioxide concentrations is available on a free telephone line—0800 556677—and from general practitioners. Daily air quality bulletins and forecasts are available on the same telephone line, on Ceefax and in some newspapers.
