Abstract / Excerpt:

The corresponding systemic uptake of Hg was estimated to 12 µg/d based on external data relating air Hg°-exposures to urinary Hg-excretions. The worst case individual showed a gross mass balance of 200 µg Hg/d connected to a systemic uptake of 70 µg Hg/d. These values were compared to the average intake of to al-Hg by a Swedish diet (2 µg/d) and to the WHO’s tolerable value for intake of total-Hg by food (45 µg/d). Upscaled to the entire Swedish population (8 mill.), the data suggests a fecal/urinary emission to the environment of 100 kg Hg yearly originating from a population load of amalgam fillings containing 90,000 kg of Hg.
