Consequences of trace metal cocktail exposure in zebra …

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.
