§ 88. Sir David Rentonasked the Minister of Housing and Local Government whether he is aware that very large quantities of sulphur dioxide are still being discharged into the air over Great Britain; and what further steps he proposes to take to implement the Clean Air Act.

This is being successfully done under the Alkali Act and Clean Air Act by requiring chimneys high enough to disperse major emissions over a wide area.
