Toxic Metals: Cadmium
Cadmium is an tremendously toxic metal commonly found in industrialized work environments, mainly where any ore is being processed or smelted. because of its low Permissible Exposure Limit (PEL), over exposures may occur even in situations where trace quantities of cadmium are found in the parent ore or smelter dust. Cadmium is used extensively in electroplating, although the nature of the operation does not usually lead to over exposures. Several deaths from acute contact have occurred among welders who have unintentionally welded on cadmium-containing alloys or working with silver solders. Cadmium is also found in industrial paints and may represent a danger when sprayed. Operations involving removal of cadmium paints by scraping or blasting may similarly pose a considerable danger. Cadmium is also present in the manufacture of some types of batteries. Cadmium emits a characteristic brown fume (CdO) upon heating, which is relatively non-irritating, and thus does not alarm the exposed individual.

Control
- Primary control should focus on inhalation. Inhaled cadmium is more readily absorbed into the body than is ingested cadmium. Intake of cadmium by ingestion and skin absorption are considered to be of relatively less importance in work-related settings.
