§ Mr. Rookerasked the Secretary of State for Trade from which countries the United Kingdom obtains supplies of fluoride powder for use in the water supply; and if he will publish the quantities imported during the past three years.
§ Mr. ParkinsonThis information is not available. Fluoride power for water fluoridation is not separately indentified in theOverseas Trade Statistics; I am advised that it is normally imported from Denmark, but sometimes other sources may be used.
