§ 43. Mr. Hastingsasked the Minister of Health, as representing the Lord President of the Council, if he will give the results of recent researches that have been carried out as to the best method of removing sulphur oxides from the air inspired and to ameliorate the worst effects of smog on the health of Londoners.
§ Mr. Walker-SmithResearch is being undertaken by the Fuel Research Station of the Department of Scientific and Industrial Research and by other official 876 and industrial organisations on methods of removing sulphur oxides from the atmosphere as part of the wider problem of the elimination of all pollutants. This work is, however, of a long-term nature and results are unlikely to be available for some time. To provide relief for those most affected by the conditions caused by serious air pollution, "smog masks" are available on prescription and trials are being undertaken of the various types of such masks as well as of ammonia dispensers and other air-conditioning devices.
§ Mr. HastingsWill the right hon. and learned Gentleman give the House a little more information about the smog masks, which seem to be very efficient? When will he have a definite report upon them, and will it be available before the coming winter, when the possibility of smog is very great?
§ Mr. Walker-SmithThere is a smog mask already available on which controlled trials have taken place. The result of those trials has been a most effective form of smog mask. In addition to that, trials are going on into the possible value of ammonia shields and ammonia bottles. I think the hon. Gentleman has an ammonia shield.
§ Mr. HastingsCan the right hon. and learned Gentleman issue some leaflet to inform the public of the details of the various methods and when and how they may be obtained?
§ Mr. Walker-SmithAs the hon. Member knows, I am answering this Question on behalf of my noble Friend the Lord President of the Council, and I will certainly draw his attention to what the hon. Gentleman has said.
