HC Deb 24 July 1957 vol 574 c50W
58. Mr. Ernest Davies

asked the Minister of Transport and Civil Aviation what further action he has taken to ensure that the emission of noxious fumes from diesel driven vehicles is kept to the minimum possible, following the recent report of the Medical Research Council.

Mr. Nugent

Research into the control of the emission of noxious fumes by road vehicles is being actively undertaken by a number of agents with the co-operation of my Ministry. The recently published report of the Medical Research Council, to which the hon. Member refers, does not suggest any new line of approach to this difficult problem.
