Even though zinc is an essential requirement for a healthy body, too much zinc can be harmful. Excessive absorption of zinc can also suppress copper and iron absorption. The free zinc ion in solution is highly toxic to plants, invertebrates, and even vertebrate fish. The Free Ion Activity Model (FIAM) is well-established in the literature, and shows that just micro molar amounts of the free ion kills some organisms. A recent example showed 6 micro molar killing 93% of all daphnia in water.Swallowing an American one cent piece (98% zinc) can also cause damage to the stomach lining due to the high solubility of the zinc ion in the acidic stomach.Zinc toxicity, mostly in the form of the ingestion of US pennies minted after 1982, is commonly fatal in dogs where it causes a severe hemolytic anemia.
zinc is toxic to human at large quantities but is not fatal at most cases.

What kind of zinc? The metal itself, or a compound, or a compound in solution?
Zinc metal isn't toxic, but zinc ions in solution definitely can be.
Maybe try Wikipedia for your question (http://en.wikipedia.org)

Nope, don't think so. I take 25mg of zinc oraly every day. It's an important mineral for the body and also helps us absorb vitamin C.
