Acute mercury poisoning
Mercury poisoning differs from the other forms of metal poisoning in
that it causes neurological symptoms rather than digestive disorders.
The source of mercury poisoning is primarily contamination of food by
polluted water containing mercuric compounds from industrial waste or
organic mercury contained in some fungicides. Food or feed grains
treated with mercury-containing fungicides are a potential source for
transmission of the metal through both animal and cereal foods. The
onset time is one week or more, at which time the symptoms of
numbness, weakness of the legs, spastic paralysis and impaired vision
are noted. Blindness and coma are extreme symptoms of the poisoning.

Chronic mercury poisoning
The symptoms of low-level, chronic mercury exposure and toxicity can
be very general and difficult to diagnose based on symptoms alone. In
addition, individuals show varying levels of sensitivity to the
presence of mercury: amalgam removal may be very important in the
recovery process of one person, while for another it may be best to
leave the amalgams in place.

Mercury is usually targeted because it is the most common toxicity
that most people have - for example, amalgams in teeth contain over
50% mercury. The remainder is made up of silver and sometimes tin,
aluminum and other metals. The mercury escapes the amalgam as a vapor
and is breathed into the body of the person carrying the amalgam.
