§ Ms RuddockTo ask the Secretary of State for the Environment what is his estimate of the total and percentage source contributions to United Kingdom PM10 particulate matter from(a) diesel cars, (b) petrol cars, (c) petrol light goods vehicles, (d) heavy goods vehicles, (e) buses, (f) domestic heating, (g) bonfires, (h) power stations and (i) other industry. [41193]
§ Mr. ClappisonThe most recently published UK inventory of emitted PM10 was published in the second report of the quality of urban air review group in December 1993, a copy of which has been placed in the Library. Of a total of approximately 250,000 tonnes of PM10 emitted in 1991, diesel cars accounted for 1 per cent., petrol cars 9 per cent., petrol light goods vehicles 1 per cent., heavy goods vehicles 12 per cent., buses 2 per cent., domestic heating 47 per cent., power stations 7 per cent., and other industry 18 per cent. No information is available on the contribution of bonfires. These proportional contributions apply to the whole of the UK and do not reflect the relative contributions in urban areas or in periods of elevated pollution levels.
