| Additional Information | | Silver exposure through dermal contact is generally characterized by argyria, a blue-gray splotch on the skin. Inhalation of silver and silver compounds has caused increased densifications of pulmonary tissues as evidenced in x-rays.3 Silver alloys and compounds are extensively used in electronics, electrical circuits, and batteries. Alloys of silver are used in the production of tableware and jewelry. Approximately 30% of the consumption of silver in industry is associated with photography. |
