§ Mr. Fox
The investigation of this pollution incident is continuing to be handled by the North-West water authority in co-operation with local industry and national wild life organisations. Fuller details can be obtained from these bodies, but I understand that the source of the organic lead has been identified as a compound used by local manufacturers, although the route by which it reached the feeding grounds cannot be traced.
I am advised that the residue of this pollution incident is now considered to 535W be fully dispersed and that there is no threat to birds wintering on the Ince bank. Further investigations into the toxic effects of this lead compound and safe limits on its discharge to the estuarial waters are proceeding.
§ Mr. Fox
I presume that the hon. Member is referring to the public availability of information under section 41 of the Control of Pollution Act 1974. I am currently considering the programme to be adopted for the implementation of this and the other outstanding provisions of part II of the Act, and will make an announcement as soon as possible.
