Sources of Mercury
MERCURY
Number 80 on the "periodic table" of elements
Sources
Mercury is widely used in industry, agriculture, and health care. Common uses of
mercury include:
- Fungicides and pesticides - a large source, used worldwide
to treat grains and seeds. Methyl mercury is the most
common form here;
- Cosmetics - mercury is added to decrease bacterial
growth;
- Dental fillings - mercury, in the past, is widely used as
silver-mercury amalgam. Dentists no longer do as they feel that
it leads to a variety of problems. The American Dental
Association still claims that there is no proven mercury
toxicity due to dental amalgams;
- Medicines - organic mercurial diuretics have been the most
common, though these are less used these days.
Mercury-containing cathartics, anthelminetics, and teething
powders were also employed in the past. Broken thermometers can
increase mercury exposure, and mercurochrome also contains
mercury;
- Coal burning - this releases mercury into the
atmosphere;
- Fish- fish may contain varying amounts of mercury.
Ocean bacteria, algae, and small fish do have some.
Mercury concentrations usually increase with the
size of the fish. An excessive intake of fish foods may
lead to increased body levels of mercury;
- Other sources of mercury are mirrors, latex
paints, fabric softeners, felt, floor waxes and
polishes, sewage sludge, laxatives containing calomel,
cinnabar jewelry, tattoo dyes, and many others. Most of
these are not specifically mercury toxic, as they do not
give off high amounts of volatile mercury. Fungicides
are the most widely used and probably the most
potentially toxic.
