§ Mr. Nabarroasked the Minister of Health, as representing the Lord President of the Council, the nature of the investigations being carried out under the auspices of the Medical Research Council, which have so far provided no evidence to support the suggestion that diesel fumes are a cause of cancer; and whether he will arrange for the intensification of those investigations.
§ Mr. Vaughan-MorganThe Medical Research Council is supporting research on the nature of the constituents of diesel exhaust fumes under different conditions both experimentally and in the field, with particular reference to the presence of cancer-producing substances; research is also in progress on the morbidity and mortality experience of groups of persons especially exposed to such fumes. My noble Friend is advised that adequate attention is being given to this problem.
