§ Mr. Campbell-Savoursasked the Secretary of State for Employment if he will list those pesticide products used in wood treatment which contain (a) dieldrin, (b) DDT, (c) Lindane, (d) tributyl tin oxide or similar compounds and (e) benzene hexachloride.
§ Mr. Peter Bottomley[pursuant to his reply, 12 February 1985, c. 136–7]: The Health and Safety Executive knows of no pesticide products used in wood treatment which contain either DDT or benzene hexachloride. Dieldrin is used in the pre-treatment of timber but is no longer approved for products used by householders or by firms specialising in wood treatment in situ. Lindane is the most commonly used insecticide marketed for wood treatment and tributyl tin oxide is one of the most commonly used fungicides. There are well over 200 products containing lindane or tributyl tin oxide or both, with frequent changes in the names of products and their constituents.
