Renal dysfunction of cadmium-exposed workers residing in a cadmium-polluted environment.

• Human exposure to cadmium may occur in both occupational and general environments. We were interested in determining whether a combination of occupational and environmental exposure to cadmium results in different levels of severity of renal dysfunction relative to that arising from environmental or occupational exposure alone. We selected 44 residents, who once were employed in a smelter and lived in a cadmium-polluted area, as group A. Another 88 subjects, who never worked in the plant, but lived in the same area, were selected as group B. Group C consisted of 88 subjects who had no history of occupational exposure to cadmium and lived in a non-cadmium-polluted area. Statistical analysis demonstrated that there was no significant difference in age or gender among the three groups, nor were there significant differences in smoking habits. The prevalence of renal dysfunction as indicated by increased excretion of beta2-microglobulin (B2M), N-acetyl-beta-D-glucosaminidase (NAG) and albumin (ALB), was higher in group A than in group B. This finding suggests that exposure to cadmium both occupationally and environmentally results in a higher prevalence of renal dysfunction, relative to those who are exposed to cadmium only in the general environment. Therefore, this specific population, who once were occupationally exposed to cadmium and lived in polluted areas, should be identified. Furthermore, health examinations of this population should be conducted in time to prevent further health damage induced by cadmium exposure.
