'''Cadmium''' is [[chemical element]] classified as a transition metal in the [[periodic table of elements]]. Extremely toxic, it is also fairly rare in [[nature]]. It occurs most often in [[compounds]] or [[minerals]], and is rarely found in [[pure form]]. As it is so deadly, it has almost no use in the bodily functions of either [[humans]] or [[animals]].

The main method of cadmium absorption in [[industrial]] exposure is by [[inhalation]], so industrial processes which generate cadmium [[dust]] or [[fumes]] should be extremely well ventilated. A single exposure to high concentrations of freshly generated cadmium oxide fumes can cause severe [[irritation]] and even lead to [[death]]. | ||
