Toxicity occurs when ingested metal causes harm to the animal. The heavy metals that most commonly cause toxicity are lead and zinc less common causes are mercury and copper. 1,3 Lead is a mineral not normally present in the body, but zinc is present in small quantities. 4 Thus, zinc toxicity results from chronic andor repeated exposure.
