In the occupational setting, contact dermatitis and ulcerations of the skin and nasal mucosa are the most commonly reported effects of chronic chromium exposure. The hexavalent chromates are the most toxic chromium compounds. [LaDou, p. 420-1] Occupational asthma has been confirmed in a printer, a tanner, a cement floorer, and in platers and welders exposed to chromates. [Malo] "Inhalation of chromium mist, dust, or fumes can produce acute bronchoconstriction, probably through a direct irritant mechanism. Chronic bronchitis and persistent abnormalities in pulmonary function have not been described following cessation of exposure. Allergic asthma due to chromium is uncommon, with fewer than two dozen cases documented in the published literature." [Rosenstock, p. 959] |
