§ Mr. Dubsasked the Paymaster General whether he will review the approval for dieldrin and tributyltin oxide to be used as wood preservatives in the light of recent water pollution incidents, such as that at Lough Neagh, in Northern Ireland.
§ Mr. TrippierThe advisory committee on pesticides is to review the approval of tributyltin-oxide for all its uses and will be making recommendations to Ministers. There are no plans for a special review of dieldrin as the only known supplier of dieldrin for use in wood preservatives will be withdrawing from the market at the end of June 1987.
