Zinc is a metal as well as an essential mineral. Your body needs zinc to function properly. If you take a multivitamin, chances are it has zinc in it. In this form, zinc is both necessary and relatively safe. Zinc can also be obtained in your diet.
Zinc however, can be mixed with other materials to make industrial items such as paint, dyes, and more. These combination substances can be particularly toxic.
This article discusses poisoning from zinc.

What to Expect at the Emergency Room
The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The patient may receive:
- Fluids (water or milk)
- Medicine (antidote) to reverse the effect of the poison
- Tube through the mouth or nose into the stomach to wash out the stomach (gastric lavage)
- Rarely, medicines called chelators that remove zinc from the bloodstream
How well a patient does depends on the amount of poison swallowed and how quickly treatment was received. The faster a patient gets medical help, the better the chance for recovery. If symptoms are mild, the person will usually make a full recovery . If the poisoning is severe, death may occur up to a week after swallowing the poison.
