Metal fume fever metals, such as chromium, vanadium and cerium. Cadmium is often replaced by other metals. Zinc or nickel plating can be used instead of cadmium plating, and brazing filler alloys now rarely contain cadmium. Metal fume fever Metal fume fever, also known as brass founders' ague, brass shakes, zinc shakes, galvie flu, metal dust fever, Welding Shivers, or Monday morning fever, is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (AlO), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are heated.

Native metal more reactive than gold. Natural alloys of the platinum group metals include: native osmium (Os,Ir,Ru), rutheniridosmine (Ir,Os,Ru), ruthenium (Ru,Ir), palladium (Pd,Pt), platinum Pt, and rhodium (Rh,Pt). In addition gold, copper, iron, mercury, tin and lead may occur in alloys of this group. As with gold, salts and other compounds of the platinum group metals are rare; native platinum and related metals and alloys are the predominant minerals bearing these metals. These metals occur associated with ultramafic intrusions and placer deposits derived from those intrusions. Native copper has been historically mined as an early source of the metal. The term Old
