Title Studies on silicosis development in foundries
Original title Cercetări cu privire la evoluţia silicozei în turnătorii [in Romanian]
Bibliographic information May 1973, Vol.22, No.5, p.299-306. 9 ref.
Abstract 226 cases of silicosis among workers in Romanian foundries were analysed, and the following parameters were examined: latency or mean exposure time to silicogenic dusts up to the first diagnosis; percentage of cases which developed; delay in passing from one stage of development to another; breakdown of cases according to length of service; mean age at first diagnosis; breakdown of cases by age groups. Results: mean exposure duration before the first diagnosis is 14.2 ± 5.8 years; the shortest latency periods are found among sand blasters and grinders (10.9 and 10.0 years), whereas foundry workers and crane operators have a prolonged latency (18 years). 70% of all cases remain stationary and 30% develop into more advanced stages after 10 years' observation. This development varies according to occupation: the disease develops in 6.8% of the cases among foundry workers and in 45.9% of the cases among sand blasters. Awareness of these factors facilitates a realistic appraisal of the silicosis hazard in the various work posts, industries and occupational groups.
