Exposure to mercury in the
population. II. Mercury release from amalgam fillings
Urinary levels of mercury (HgU) were
measured in 93 males and females aged 18-63 years. Subjects with amalgam
fillings (n = 72) had, on average, significantly higher levels of mercury in
urine (mean = 0.57 microgram Hg/l and 0.79 microgram Hg/g creatinine,
respectively) than subjects without amalgam fillings (n = 21; mean = 0.18
micrograms Hg/l and 0.24 microgram Hg/g creatinine, respectively). Urinary
mercury excretion was significantly correlated with the number of amalgam
surfaces (log HgU (microgram/l) vs. number of amalgam fillings: r = 0.435, P
less than 0.001; log HgU (microgram/g creatinine) vs. number of amalgam
fillings: r = 0.575, p less than 0.001). The results indicate that internal
mercury exposure from amalgam fillings is, on average, higher than internal
exposure to mercury from food and other sources.
