||Silicosis in Brazilian pit diggers - Relationship between dust exposure and radiologic findings
||Mar. 1995, Vol.27, No.3, p.367-378. Illus. 20 ref.
||A study of 366 pit diggers in northeastern Brazil, including a questionnaire and chest X-ray, revealed 121 (33.306%) silicotics and possible silicotics. Since the study population comprised itinerant workers performing occasional digging activities, a dust exposure index was developed to determine the exact duration of dust exposure; the mean value of the index was 391.4 days. A clear association was revealed between duration of exposure and the incidence of silicosis. The geoclimatic conditions of the area resulted in very high dust concentrations and the silicosis occurred in its accelerated form.
