Arsenic is also found in food, water, soil, and air. [132] Arsenic is absorbed by all plants, but is more concentrated in leafy vegetables, rice, apple and grape juice, and seafood. [ 133 ] An additional route of exposure is inhalation of atmospheric gases and dusts. [ 134 ]
Arsenic forms colorless, odorless, crystalline oxides As 2 O 3 ("white arsenic") and As 2 O 5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic(V) acid is a weak acid and the salts are called arsenates , [ 5 ] the most common arsenic contamination of groundwater , and a problem that affects many people.
A 2007 study found that over 137 million people in more than 70 countries are probably affected by arsenic poisoning of drinking water. The problem became a serious health concern after mass poisoning of water in Bangladesh. [1] Arsenic contamination of ground water is found in many countries throughout the world, including the US.

Arsenic was the most prevalent chemical found in the study, with almost 80% of formula samples testing positive. Rice-based baby foods like snack puffs had some of the highest levels of arsenic as ...
The US Food and Drug Administration has finalized new standards that foods must meet before they can be labeled as “healthy.”. Requirements now include limits on saturated fat, sodium and ...
Arsenic poisoning is a global problem arising from naturally occurring arsenic in ground water. The evidence that arsenic may be a beneficial nutrient at trace levels below the background to which living organisms are normally exposed has been reviewed. [3]
Arsenic, according to the National Institute of Environmental & Health Sciences, is an element found naturally in the environment, such as water, soil, and air. This can make its way to food. This ...
In humans, arsenic of these valences is readily absorbed by the gastrointestinal tract, which accounts for its high toxicity. Pentavalent arsenic tends to be reduced to trivalent arsenic and trivalent arsenic tends to proceed via oxidative methylation in which the trivalent arsenic is made into mono, di and trimethylated products by ...
