15/4/2020· The ''calcium and metal'' group also accumulated lower concentrations of arsenic and lead in feathers compared to the ''metal'' group. Our results suggest that chronic exposure to a cocktail of metals at low concentrations has deleterious effects on s, which can be limited through calcium intake.
The reason why, in a few cases, aluminium is referred to as a metalloid, from the article: It has some properties that are unusual for a metal; taken together, these are sometimes used as a basis to classify aluminium as a metalloid.
