Objective:
To explore effects of tantalum and its oxide on the exposed workers.
Methods:

Results:
Workplace air concentration of tantalum and its oxide averaged 0.1 - 7.6 mg/m(3). There was no significant difference in prevalence of symptoms and signs and biochemical, pulmonary function, chest X-ray and electrocardiograph examinations between the exposed and control workers.
Conclusion:
No adverse effect of tantalum and its oxide on the exposed workers was found.
