Arsenic levels in Oregon waters.

Traditional and Alternative Technologies for Arsenic Removal from Drinking Waters

Arsenic contamination in drinking waters has been a serious public health concern due to both carcinogenic and other health effects. The main sources of human exposure to arsenic are the drinking waters. Arsenic can cause chronic illness and death, even at low levels of arsenic concentration in drinking waters. There are many technologies available for removal of arsenic from contaminated drink...

Arsenic in Ground Water of the Willamette Basin, Oregon

A New and Efficient Method for the Adsorption and Separation of Arsenic Metal Ion from Mining Waste Waters of Zarshouran Gold Mine by Magnetic Solid-Phase Extraction with Modified Magnetic Nanoparticles

Widespread arsenic contamination of mining wastewater of Zarshouran (West Azerbaijan province) has led to a massive epidemic of arsenic poisoning in the whole of surrounding areas. It is estimated that approximately all agriculture fields are being irrigated with the water that its arsenic concentrations elevated above the World Health Organization’s standard of 10 parts per billion. A novel ad...

The Effectiveness of Arsenic Remediation from Groundwater in a Private Home

Private wells are the source of drinking water for approximately 15% of households in the United States, but these wells are not regulated or monitored by government agencies. The well waters can contain arsenic, a known carcinogen that occurs in groundwater throughout the nation at concentrations that can exceed the Maximum Contaminant Level defined by the U.S. Environmental Protection Agency ...

Thioarsenates in geothermal waters of Yellowstone National Park: determination, preservation, and geochemical importance.

Mono-, di-, tri-, and tetrathioarsenate, as well as methylated arsenic oxy- and thioanions, were determined besides arsenite and arsenate in geothermal waters of Yellowstone National Park using anion-exchange chromatography inductively coupled plasma mass spectrometry. Retention time match with synthetic standards, measured S:As ratios, and molecular electrospray mass spectra support the identi...
