While these indicators are excellent indicators of low body iron stores, slight decreases in iron stores are of debatable clinical significance. 2 Toxicity in Humans from Excessive Exposure Lethal Effects. Excessive doses of soluble salts of iron or copper by the oral route, which may be ingested by accident or with suicidal intent, give rise to extensive and severe gastrointestinal manifestations, systemic toxicity, shock, and death (19,50). Toxic Effects with Clinical Significance. Clinical disease (without fatal outcome) may occur as a result of ingestion of high doses of soluble selenium salts.

Also, the database used to evaluate nutrient toxicity often comes from studies of human populations and is thus less uncertain with respect to its use in human health risk assessments than that from animal studies. Unlike nonessential chemicals, tissue levels, and therefore biological effects, of essential metals are under homeostatic control. Also, tissue levels may be markedly altered by speciation and bioavailability from various dietary matrices, as well as nutrient-nutrient and nutrient-diet interactions that might occur.
