[Effects of tantalum and its oxide on exposed workers].
OBJECTIVE
To explore effects of tantalum and its oxide on the exposed workers.


METHODS
Health examination for 113 workers exposed to tantalum and its oxide and a field survey for occupational hygiene in the workplace were carried out.


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.


CONCLUSIONS
No adverse effect of tantalum and its oxide on the exposed workers was found.
