§ Mr. Doddsasked the Parliamentary Secretary to the Ministry of Works, as representing the Lord President of the Council, what arrangements have been made by the Medical Research Council for a series of tests in London and several provincial towns in an endeavour to ascertain what effect the exhaust fumes of motor vehicles have on the health of people in congested areas.
§ Mr. BevinsThe Medical Research Council is undertaking an extensive programme of work on the effects on health of atmospheric pollution, including pollution by engine exhaust fumes. A Working Party on the constituents of atmospheric pollution and means of protection against it has recently been appointed to co-ordinate these studies. New methods are being sought to determine the gases present in the atmosphere, and it is hoped to apply these methods soon in London and possibly other centres. It is also planned to undertake blood estimations on men who are exposed to vehicle exhaust fumes for long periods.
