HC Deb 21 June 1966 vol 730 c33W
Earl of Dalkeith

asked the Minister of Technology whether he will initiate research into methods of mitigating the harmful effects of diesel exhaust fumes on human respiratory organs; and whether he will publish a comprehensive report showing what information he has from other Governments and the World Health Organisation who have carried out similar researches.

Mr. Cousins

No. While diesel exhaust fumes may often be unpleasant, I am advised that there is no evidence that the concentrations of these fumes found in the streets may constitute a hazard to health.

Information about air pollution by diesel exhausts is freely exchanged on an international basis and I do not consider that the publication of a comprehensive report is needed.
