title: [Mercury concentrations in the air, in the blood and urine of dentists in dental clinics and free practice].
abstract: The concentration of mercury in the air was measured for 12 assistants and students, 27 dentists, and 42 dental assistants. The total concentration of mercury in the blood and the urine was also determined and compared with a control group. The results were as follows: 1. The highest concentration of mercury in the air (3--12 microgram Hg/m3) appeared only briefly. 2. The mercury concentration in the spontaneous urine of the dentists and dental assistants (6 microgram/l) was only slightly higher than that for the nonexposed control group (4 microgram/l). 3. The mercury concentration in the whole blood of the students (22 microgram/l) was the highest; that of the dentists and dental assistants (with several years exposure to mercury vapor, 7.0 and/or 6.5 microgram/l) was only slightly higher than that of the nonexposed control group (5 microgram Hg/l).
