Exposure to arsenic dust and fumes has been linked to lung cancer in smelter and pesticide plant workers. Inorganic arsenic compounds are acutely toxic. Arsenic metal is used in alloys, in glass, as a radioactive tracer. Compounds are used in pesticides and wood preservatives. No odor reported for metal or most compounds.
Arsenic trioxide has a garlic-like odor.
Does not bioaccumulate. As with all chemicals, the type and severity of health effects associated with exposure to arsenic and related compounds depend on the level, duration, and route of exposure. The age, sex, weight, preexisting health condition, and overall susceptibility of the individual also determine the health effects he or she may experience. Individuals show a wide range of variability in their tolerance of chemical exposure. Arsenic may be an essential trace nutrient in some animals, and may be one in humans.
