§ 40. Mr. ROBERT YOUNG
asked the Minister of Health whether he is aware that about 70 per cent. of air pollution is the result of smoke from industrial chimneys; whether his Department has taken any steps to investigate the problem of smoke prevention by the use of smoke-filtering apparatus and with what result: and whether he will inquire what has been done by way of experiment by the corporations of our larger cities?
§ 53. Captain REID
asked the Minister of Health whether, in view of the fact that 06 per cent. of the air pollution is due to smoke from industrial chimneys and that such air pollution is known to be injurious to health, any legislation is contemplated which would make the use of smoke-filters in factories compulsory?
For the country generally, the proportions of industrial smoke stated by the hon. Members appear to be much too high. I hope to introduce a Bill on the subject next Session. T have no special information about smoke filters, but if the hon. Members have any device in mind, I shall be pleased to receive particulars from them.
§ Sir WILFRID SUGDEN
Do I understand that the National Physical Laboratory is not now conducting experiments on this matter?
§ Mr. HARDIE
Is it not a fact that the greatest contributor to smoke pollution is the domestic fire?
