HC Deb 05 March 1987 vol 111 c650W
Mr. Bright

asked the Secretary of State for the Environment on how many occasions in each of the last five years ozone levels monitored in the open air have exceeded those permitted as a maximum in factories.

Mr. Waldegrave

The interim report of the United Kingdom photochemical oxidants review group, copies of which I have had placed in the Library of the House, analysed the United Kingdom ozone monitoring data available up to 1985. Only during the exceptional summer of 1976 could the occupational exposure limit for ozone be said to have been exceeded at some sites in the south-east. Data for 1986 have yet to be fully verified but it is unlikely that they will change that conclusion.
