§ Mr. McGradyTo ask the Secretary of State for Northern Ireland if he will give the air quality results for central Belfast, for January, June, October and December each year from 1985 to the present for carbon dioxide, carbon monoxide, sulphur dioxide and low level ozone and any other relevant measurements for which he has results.
§ Mr. NeedhamCarbon dioxide, carbon monoxide and low-level ozone have not been monitored in Belfast to date, although carbon monoxide and ozone are to be included amongst the pollutants measured at a new city centre monitoring station which will come into operation shortly.
Sulphur dioxide is monitored at nine sites throughout Belfast, including the city centre, by the Warren Spring laboratory and Belfast city council. Smoke levels are also measured. The results from April to March are published annually. The figures for the months requested are set out in the table, and include provisional, unpublished data for June, October and December 1991.
