HC Deb 05 May 1958 vol 587 c78W
53. Mr. J. Howard

asked the Paymaster-General what precautions are taken to minimise the sulphuric acid content of smoke emitted by the Marchwood power station; and if he is satisfied that the smoke is harmless to human beings and to property.

Sir I. Horobin

Special precautions including the use of neutralising substances are taken in operating the furnaces at this station to minimise the acid content of the flue gases and local measurements of acid concentration do not reveal any significant increase since the station began operation. As to the effects of the smoke, I understand that there have been some cases in which near-by property has suffered minor corrosion, mainly of paintwork. There is no evidence of harm to human beings.
