OBSERVATIONS ON ATMOSPHERIC AIR POLLUTION CAUSED BY ASBESTOS
Published 1965 · Biology, Medicine
Introduction The mining (quarrying) of asbestos in Finland has been carried out for approximately fifty years. Current production is about 15,000 tons of anthophyllite asbestos per year. In his work on nonoccupational endemic asbestosis, published in 1960, R. Kiviluoto found calcifications of pleura on X-ray examination in approximately 600 people living around the mines.' V. Raunio, who at present is continuing the study of the incidence of pleural calcifications in the population around the mines, has mentioned that 1,300 more cases have been found, Kiviluoto, however, estimates that about ten per cent of the population living around the mines might have pleural plaques. At the request of V. Raunio and the Finnish Asbestos Company, Suomen Mineraali, the Institute of Occupational Health has performed some air pollution studies around the mines, to investigate the presence of asbestos in the air. Some preliminary observations have been made which are included in the following material.
