§ Dr. A. Thompsonasked the Minister of Health, as representing the Minister for Science, whether he will take steps to ascertain to what extent workers, who are by their occupation exposed to high concentrations of traffic fumes, especially the exhaust products of petrol and diesel vehicles, are particularly vulnerable to bronchitis.
§ Mr. PowellResearch is already being done on this problem. The Medical Research Council has in hand studies on the physical and chemical characteristics of pollutants, including exhaust fumes, and on the significance of polluted air in relation to chronic bronchitis. Studies recently made by London Transport do not indicate that men working in diesel bus garages, where high concentrations of exhaust fumes may be expected. are particularly vulnerable to bronchitis.
