HC Deb 12 December 1991 vol 200 cc521-2W
Mr. Cash

To ask the Secretary of State for Social Security whether he proposes any changes in the series of statistics covering households with below average incomes.

Mr. Hanley

There is no regular monitoring regime for freshwater fish flesh. Monitoring and testing are undertaken, however, where problems are suspected.

In 1990, at the request of the Foyle Fisheries Commission, a number of samples of salmon from the River Foyle estuary were analysed for contaminants.

In 1986–87 Northern Ireland scientists participated in a United Kingdom survey of pesticide and heavy metal residues in eels from freshwater sites. A similar survey is planned for 1995.
