Mercury concentrations in blood from Danish dentists

Abstract
Abstract — Blood samples from a group of 130 dentists and a control group of 40 blood‐donors were analyzed by cold vapor atomic absorption spectrophotometry in order to evaluate the extent of mercury exposure. The median blood concentration of mercury was 4.0 (range: 1.2–19.2) μg/1 for dentists and 2.0 (1.1–4.6) μg/1 for controls (2PP<0.01). It was concluded that none of the examined dentists had blood concentrations above the level (35 μg Hg/1) associated with the hygienic threshold limit.
