1.1 Identity. Arsenic exists in oxidation states of −3, 0, 3 and 5. It is widely distributed throughout Earth's crust, most often as arsenic sulfide or as metal arsenates and arsenides. In water, it is most likely to be present as arsenate, with an oxidation state of 5, if the water is oxygenated.

January 1, 2000. Concentrations of naturally occurring arsenic in ground water vary regionally due to a combination of climate and geology. Although slightly less than half of 30,000 arsenic analyses of ground water in the United States were 1 μg/L, about 10% exceeded 10 μg/L.
6. Nevada. Wells in Northern Nevada have some of the highest arsenic levels in the country. Believe it or not, the City of Reno has to blend its well water with water from the Truckee River just to dilute the arsenic. Shockingly, the average well in Nevada has arsenic levels of 55 ppb, or five times the federal limit.
Higher levels of arsenic tend to be found more in ground water sources than in surface water sources (lakes and rivers) of drinking water. Compared to the rest of the United States, the western states have more water systems with arsenic levels greater than 10 micrograms per liter (µg/L, ppb).
An increased risk of skin cancer in humans is associated with chronic exposure to inorganic arsenic in contaminated water and the workplace. Arsenic-induced skin cancer is frequently characterized by lesions over the entire body, mostly in unexposed areas such as the palms, soles, and; trunk. More than one type of skin cancer may occur in a ...
Introduction. Arsenic (As) is a common drinking water contaminant that is often found in groundwater wells [ 1 – 6 ]. Even at very low concentrations, chronic consumption of As in drinking water has been strongly associated with a variety of cancers and other adverse health effects in humans [ 7 – 13 ].
In the year 1993, the water samples of some tubewells located in the northern bordering area of Bangladesh were examined for arsenic contamination and found to contain arsenic in the range of 0.059–0.388 mg/L, which was higher than the Bangladesh standard level of arsenic in drinking water (0.05 mg/L). 3, 13, 21 – 23 Within …
Ongoing exposures to toxic chemicals such as arsenic continue to pose a significant threat to public health. The World Health Organization (WHO) estimates that > 200 million persons worldwide might be chronically exposed to arsenic in drinking water at concentrations above the WHO safety standard of 10 µg/L (Table 1).Arsenic is a …

Introduction. Arsenic is a naturally occurring, semimetallic element widely distributed in the Earth's crust. Arsenic levels in the environment can vary by locality, …
Introduction. The primary routes of arsenic entry into the body are ingestion and inhalation. Dermal absorption also occurs, but to a lesser extent. The half-life of inorganic arsenic in humans is about 10 hours [Rossman 2007]. Arsenic undergoes biomethylation in the liver. Approximately 70% of arsenic is excreted, mainly in urine [Rossman 2007].

Arsenic ingested by the mother can cross the placental barrier. Gestational exposure to arsenic has been associated with effects at pre-and perinatal stages, as well as during childhood. These effects include adverse pregnancy outcomes and alterations to the cardiovascular, respiratory, and immune system.
