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.
对93名年龄在18至63岁之间的男性和女性测量了尿汞水平（HgU）。有汞合金填充物的受试者（n = 72）尿汞水平平均显著高于无汞合金填充物的受试者（n = 21），分别为平均0.57微克汞/升和0.79微克汞/克肌酐，后者分别为平均0.18微克汞/升和0.24微克汞/克肌酐。尿汞排泄与汞合金表面数量显著相关（log HgU（微克/升）与汞合金填充物数量：r = 0.435，P < 0.001；log HgU（微克/克肌酐）与汞合金填充物数量：r = 0.575，p < 0.001）。结果表明，来自汞合金填充物的体内汞暴露平均高于来自食物和其他来源的汞的体内暴露。
