摘要

The mercury levels of urine and hair in 92 dentists and 80 bank staffs were determined by the cold vapor atomic absorption spectrophotometer and hydride formation system. The dentists were sampled by stratified proportional systematic method from the dentist practicing in Taipei city, and the bank staffs as control group.
The results indicated the geometric mean of dentists' mercury levels in urine and hair were 5.54×÷l.88μg/g creatinine, and 6.31×÷1.85μg/g. Those levels of the dentists were significantly higher than those of control, (p＜0.0001) l.90×÷3.40μg/g creatinine in urine and 4.14×÷1.53μg/g in hair.
And the results showed the hair mercury concentration is related to the floor type of dental clinic, suction type of old amalgam removed and working experience hours.
