Mercury levels in dental students and faculty measured by neutron activation analysis. 1980

P M Sinclair, and P R Turner, and R B Johns

Samples of head hair, fingernails, and toenails were taken from 61 dental students and faculty members. The mercury levels were analyzed using a simple neutron activation analysis technique which proved to be easily applicable to large numbers. Significant results were found for the head hair and fingernail groups. There may be a correlation between the higher mercury levels and increased pressure of work, which might result in decreased standards of mercury hygiene.

UI MeSH Term Description Entries
D008628 Mercury A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.
