HC Deb 29 October 1956 vol 558 c91W
47. Mr. Awbery

asked the Minister of Health, as representing the Lord President of the Council, if he will hold an inquiry into the effects on the lungs of the dense noxious diesel smoke fumes emitted from vehicles on the highway using crude oil ; and to what extent it is a contributory cause of lung cancer.

Mr. Turton

Investigations are already being made, under the auspices of the Medical Research Council, into the nature of the exhaust products of diesel engines under different running conditions, and the extent to which they may contain cancer-producing substances or other harmful constituents.
