§ Mr. Eadieasked the Secretary of State for Trade and Industry what estimates he has made of the cost of dealing with sulphur dioxide pollution in power stations in Great Britain.
§ Mr. EmeryThere is at present no practical economic method of removing sulphur dioxide from the products of combustion and for many years now generating stations in the United Kingdom have been built with chimneys of a height agreed with the Alkali Inspectorate, sufficient to disperse SO2emissions so that concentrations of the gas at ground level are harmless.
