Percentage of ATSDR MRL is computed as arsenic
exposure (in [micro]g As/kg of body weight per day) due to a particular food or beverage divided by the ATSDR MRL for inorganic arsenic

contaminated ground water is a major environmental health hazard throughout the world including India.
The most common oxidation state for arsenic
is -3 (arsenide), +3 (arsenates (III) or arsenites, and most organoarsenic compounds) and +5 (arsentate (V) : the most stable inorganic arsenic
