asked the Secretary of State for Wales if he is satisfied with the frequency of checks on atmospheric pollution in the area of South Monmouthshire; what guidance he gives to local authorities on this matter; and if he will make a statement.

I am satisfied that the regular monitoring for smoke and sulphur dioxide, the work of the alkali inspectorate in relation to industrial emissions, and the survey of heavy metal atmospheric pollution which I announced last November provide an adequate check on atmospheric pollution in the area. My Department is always ready to advise local authorities on air pollution problems.
