§ 54. Mr. Oakesasked the Secretary of State for the Environment if he will, as a matter of urgency, call for a report on the toxic heavy metals content of major rivers.
§ Mr. Peter WalkerSix months ago I initiated a survey of concentrations of heavy metals and other substances in river waters and sediments in seven river authority areas. As soon as the results have been evaluated I shall consider whether any change is required in the arrangements for monitoring for toxic substances in rivers; meanwhile, a close watch is being kept on critical areas.
