§ 9. Mr. Fitchasked the Paymaster-General to what extent research experiments have shown that greater quantities of sulphur dioxide are given off from oil burning than from coal burning.
§ Mr. MaudlingThe amount of sulphur dioxide released by any given operation depends both upon the type and upon the quantity of the coal or oil that is used. As the sulphur content of both fuels varies widely according to type and as the quantity required depends upon the type selected, there can be no general answer to the hon. Member's Question.
§ Mr. FitchSurely the Paymaster-General is evading the Question? Is it not a fact that the ratio of sulphur dioxide given out from coal burning and oil burning is one to one and a half? In view of that, will he consider restricting the use of oil in smokeless zone areas?
§ Mr. MaudlingMy Answer was given on the basis of the best scientific advice to which I have access. I think the hon. Member will find it to be the most accurate Answer that can be given.
