§ 83. Mr. Ellis Smithasked the Minister of Agriculture, Fisheries and Food what research has been undertaken and what have been the results concerning the fluorine pollution of the air in Fenton, Longton, Stoke-on-Trent and other parts of the country; and what research has been undertaken at the request of the National Farmers' Union.
Mr. AmoryMy Department is studying fluorosis in livestock at Fenton Manor Farm, Stoke-on-Trent. The work includes experimental treatment to alleviate its effects on cattle; no firm conclusions on this can be expected for some time. Pigs and poultry are being reared there, apparently without ill effect. Surveys to assess the extent of danger to stock in some other industrial areas are nearing completion. These investigations represent the extension of work on fluorosis18W which the N.F.U. desire to see. I am writing more fully to the hon. Member in reply to his recent letter on the subject.
