Mr. William O'BrienTo ask the Secretary of State for the Environment how many of the sites for monitoring air pollution operated by the National Environmental Technology Centre are sited at a road; and if he will list the sites.
§ Mr. AtkinsThe National Environmental Technology Centre currently operates the automatic monitoring station at the Cromwell road kerbside site on behalf of the Department of the Environment. The National Environmental Technology Centre is also contracted by the Department to co-ordinate the on-going national survey of nitrogen dioxide using passive diffusion tube samplers. Measurements are being made at nearly 1,300 locations across the United Kingdom. One in four of the diffusion tubes sites have been specifically chosen to be at roadside locations. The locations of these sites can be obtained from the National Environmental Technology Centre.
