Occupational and environmental exposure to arsenic. Bibliographical update for research. Se excreta por orina, heces y piel. Arsenic is a metalloid present in ores containing copper and causes a severe occupational disease.

The main occupational exposure occurs in copper metallurgy. It enters the human body by the respiratory, digestive and skin tracts. It is transformed into dimethylarsinic and methylarsonic acids that are excreted by urine, feces or skin. Its trivalent compounds are cumulative and might cause cancer in several organs.

Arsenic binds with a covalent link to mercapto sulfur groups and it uncouples oxidative phosphorylation, suggesting a non-hydrolytic inhibitory action in mitochondria. Some fish and shellfish contain high amounts of organic arsenic. The threshold level value in work environment is 0. Arsine is the most toxic arsenical compound.

Endemic regional hydroarsenicism is an environmental disease caused by water arsenic contents in some regions. Arsenic, occupational and environmental exposure, toxicology, treatment, bibliography.
