§ Mr. Ron Daviesasked the Secretary of State for the Environment if he will give a timetable for publication of the results of studies being made by (a) the acid waters review group, (b) the acid soils review group and (c) studies on ozone made at the energy technology support unit at Harwell.
§ Mrs. RumboldI expect to receive a report from the Acid Waters Review Group early in 1986. There is no acid soils review group but the Atmospheric Effects Review Group is considering the effects of acidity on terrestrial systems; I expect this group to report in the latter half of 1986. The Department of the Environment is now funding 23W detailed modelling studies on the generation and occurrence of atmospheric ozone and has set up a Photochemical Oxidants Review Group; I expect this group to report in about 18 months.
