Parenchymal and pleural fibrosis in construction workers.

Exposure to mineral dust was studied among construction workers (N = 437) with the aid of a questionnaire and a chest X-ray examination of the lungs. The results of the questionnaire showed that 81% of the construction workers had been exposed to asbestos. Exposure had occurred in all of the occupational groups studied. Pleural plaques and/or lung fibrosis (ILO greater than or equal to 1/1) were found in 26% of the examined workers; the prevalence varied from 18 to 40% among the various occupational groups. Comparison with a representative sample of the Finnish male population from another investigation indicates that the frequency of lung fibrosis (ILO greater than or equal to 1/1) is at least two times higher among the examined construction workers than among the general population. It seems likely that exposure to asbestos dust can be considered an etiological factor for an appreciable number of the X-ray findings.

Urinary beta2 microglobulin related to chronic low level exposure to metallic cadmium dust in Finnish cadmium processing workers.

The determination of urinary beta2 microglobulin is a sensitive method for screening groups which run the risk of developing renal tubular damage due to cadmium exposure. In this study, the urinary beta2 microglobulin excretion of 78 male workers who had been exposed to cadmium dust levels of 6.3-11.0 microgram/m3 from 0.5 to 4 h daily for an average of four years was compared to 35 nonexposed male workers. Possible effects of smoking on renal beta2 micorglobulin excretion were controlled. The results indicate that the levels of cadmium to which the workers were exposed have no measurable renal effects on the health of workers.
