over the counter address. By implication they must be a normal
part of our diet and, if lacking, zinc supplements meet that

[ ZINC GROUP ELEMENTS: Toxicity of the elements and their
The toxicity of the metals increase in the order zinc, cadmium,
mercury. The toxicity of zinc is low. In drinking water zinc
can be detected by taste only when it reaches a concentration of
15 parts per million (ppm); water containing 40 parts per
million zinc has a definite metallic taste. Vomiting is induced
when the zinc content exceeds 800 parts per million. Cases of
fatal poisoning have resulted through ingestion of zinc chloride
or sulphide, but these are rare. Both zinc and zinc salts are
well tolerated by the human skin. Excessive inhalation of zinc
compounds can cause such toxic manifestations as fever,
excessive salivation, and a cough that may cause vomiting; but
the effects are not permanent. ]
Sounds like it will take quite a lot of zinc vapor before it
kills you but as usual moderation and caution is in order.
