Molybdenum
Molybdenum is a naturally occurring metal and essential nutrient for most living organisms. It is also used in metallurgy and as a component in fertilizers to prevent molybdenum deficiency in plants. Exposure to elevated concentrations of molybdenum beyond what is necessarily for nutrition may lead to adverse kidney effects.
