Title Effects of low concentrations of asbestos - Clinical, environmental, radiologic and epidemiologic observations in shipyard pipe coverers and controls
Bibliographic information 2 Dec. 1971, Vol.285, No.23, p.1271-1278. Illus. 36 ref.
Abstract 101 pipe coverers engaged in new ship construction and 94 controls matched for age, duration of employment and smoking habits were surveyed as regards environmental exposure to asbestos dust, respiratory function, clinical and radiological findings, and other diseases. Dust exposure had been near the threshold limit value of 175p/cm3. Asbestosis was found to be 11 times more common among pipe coverers than among controls; it was found first after 13 years' exposure, and its prevalence was 38% after 20. The study emphasises that low concentrations of asbestos can lead to pulmonary fibrosis and suggests that the threshold limit value should be lowered.
