Sources of Mercury Exposure

• Dental Amalgam
• Fish, especially tuna, marlin and shark
• Pesticides, fungicides
• Paint, especially marine
• Mercurial skin creams
• Broken mercury thermometers with inadequate removal
• Thiomersal (medical preservative)
• Medical and scientific calibration instruments (manometers)
• Sites of devastating accidents, such as 9/11
• Fluorescent light tubes, especially older models
• Geothermal or geological polluted drinking water
• Industrial air pollution from coal fired power stations
• Crematoria and environs

Nearly 80% of the world’s dental carriers are filled with dental amalgam (silver fillings). This unstable alloy contains approximately 50% mercury which continuously releases elemental mercury. Amalgam is estimated to contribute, on average, 50% of total Hg exposure from all sources.
