The free zinc ion in solution is highly toxic to bacteria, plants, invertebrates, and even vertebrate fish. [ 2 ] [ 3 ] [ 4 ] Zinc is an essential trace metal with very low toxicity in humans. [ 1 ] [ 5 ]
Zinc is added to the soil primarily through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. Excess zinc is toxic to plants, although zinc toxicity is far less widespread. [5]
Zinc toxicity has been seen to occur at ingestion of greater than 225 mg of zinc. [18] Excessive absorption of zinc can suppress copper and iron absorption. The free zinc ion in solution is highly toxic to bacteria, plants, invertebrates, and even vertebrate fish. [19] [20] [21]
When zinc toxicity does happen, it has been shown to come "almost exclusively" from supplements over food, Halperin adds. That said, it's also not recommended to eat more than 40 milligrams per ...

A relatively non-toxic metal to humans and the second most abundant, the body has 2-3 grams of zinc. [1] It can enter the body through inhalation, skin absorption, and ingestion, [5] with the latter of the bunch being the most common. The mucosal cells of the digestive tract contain metallothionein proteins that store the zinc ions. [1]
