Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta , causing serious arsenic poisoning to large numbers of people.
hyperaccumulators and contaminants : Al, Ag, As, Be, Cr, Cu, Mn, Hg, Mo, naphthalene, Pb, Se, Zn – accumulation rates ; Contaminant Accumulation rates (in mg/kg dry ...
Arsenic may be solubilized by various processes. When pH is high, arsenic may be released from surface binding sites that lose their positive charge. When water level drops and sulfide minerals are exposed to air, arsenic trapped in sulfide minerals can be released into water. When organic carbon is present in water, bacteria are fed by ...
Short-term exposure to high levels of inorganic arsenic can result in nausea, vomiting, bruising, and numbness or burning sensations in the hands and feet. For adults, long-term exposure to ...
The arsenic (As) cycle is the biogeochemical cycle of natural and anthropogenic exchanges of arsenic terms through the atmosphere, lithosphere, pedosphere, hydrosphere, and biosphere. Although arsenic is naturally abundant in the Earth's crust, long-term exposure and high concentrations of arsenic can be detrimental to human health. [1] [2]
Update: This article has been updated to include a statement from Starkey Water. A recent study by the Center for Environmental Health (CEH) has revealed high levels of metal arsenic in two brands ...
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
"This exceedance of the arsenic drinking water standard is further evidence that violations have occurred at CRRUA," the NMED press release stated. The NMED sent the utility an information demand ...
