§ Mr. Canavanasked the Secretary of State for Scotland what his Department considers to be a safe level of polychlorinated biphenyls, polychlorinated dibenzodioxin (especially 2, 3, 7, 8 TCDD) and polychlorinated dibenzofurans in milk, soil, water and human tissue.
§ Mr. John MacKayThe steering group on food surveillance, the committee on the medical aspects of928W contamination of air, land and soil and the interdepartmental committee on dioxins have been asked to look at various aspects of the toxicological significance of polychlorinated biphenyls, dioxins and dibenzofurans. None is yet in a position to comment.
Some guidance already exists in relation to short-term and long-term exposure to airborne polychlorinated biphenyls. This is contained in guidance note EH 40/86 "Occupational Exposure Limits 1986" issued by the Health and Safety Executive, copies of which are available in the Library.
