§ Mrs. Ann Taylor
To ask the Secretary of State for the Environment when he will publish the results of the national materials exposure programme; how many times the acid deposition building effects review group has met since the publication of its 1989 report; when the group will produce its next report; and if he will make a statement.
§ Mr. Maclean
The acid deposition building effects review group last met in September 1991. There are no plans at this stage to produce a second report.
Results of the national materials exposure programme will be published in the July 1992 edition of the scientific journal Atmospheric Environment. A major review of the first four years of the NMEP programme is to be produced by the end of 1992.
