Researchers find natural manganite ores have significant effect on environmental behavior of arsenic
The ecological risk of pollutants is closely related to their environmental behavior. A research team led by Prof. Fan Qiaohui from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences conducted an in-depth stud.....»»
Researchers discover corn reduces arsenic toxicity in soil
When crops grow in arsenic-contaminated soil, this toxic element accumulates in the food chain. A study involving the University of Basel has now discovered a mechanism used by corn plants to reduce arsenic uptake: the key factor is a special substan.....»»
Study suggests millions are at risk using high arsenic water for cooking
The use of water contaminated with higher than recommended levels of arsenic could pose a serious health risk to millions, a new study from the University of Sheffield has found......»»
Contamination around Fort Story base is under control, Navy"s five-year review says
The Navy released recently a five-year review of an environmental restoration program at Virginia's Joint Expeditionary Base Fort Story, finding that environmental contamination of industrial solvents and arsenic at two sites is under control......»»
How can we avoid drinking forever chemicals and arsenic?
It is found in polar bears and virgin forests. It is in our shellfish, hot cocoa mixes, and kale......»»
One-atom-thick phosphorus/arsenic alloy ribbons could improve batteries, solar cells and sensors
Researchers at UCL have created one-atom-thick ribbons made of phosphorus alloyed with arsenic that could dramatically improve the efficiency of devices such as batteries, supercapacitors and solar cells......»»
New study uncovers potential risk of arsenic release from sediment under organic matter influence
Researchers from the Chinese Research Academy of Environmental Sciences have conducted a study to assess the impact of environmental factors and microbial communities on the mobilization of arsenic (As). The findings, published in the journal Environ.....»»
As water levels drop, the risk of arsenic rises
When John Mestas' ancestors moved to Colorado over 100 years ago to raise sheep in the San Luis Valley, they "hit paradise," he said......»»
Researchers use calcium materials to reduce arsenic availability in agricultural soil
Of all the heavy metals appearing as pollutants in agricultural soil, arsenic (As) poses the greatest threat to human health. As is a common pollutant in upland arable soils, which account for nearly 90% of the world's agricultural soil. In its penta.....»»
Arsenic contaminates private drinking water wells across the western Great Basin
In the arid and drought-stricken western Great Basin, sparse surface water means rural communities often rely on private groundwater wells. Unlike municipal water systems, well water quality in private wells is unregulated, and a new study shows that.....»»
Enhanced arsenic detection in water, food, soil
It is a cruel paradox that on a planet with a surface mostly covered by water, hundreds of millions of people don't have access to clean drinking water. As for the pollution of potable and natural water sources, one of the main culprits is arsenic, a.....»»
Highest metal concentrations in US public water systems found among Hispanic/Latino and American Indian communities
Significantly higher arsenic and uranium concentrations in public drinking water have been linked to communities with higher proportions of Hispanic/Latino, American Indian/Alaskan Native, and non-Hispanic Black residents, according to a new study at.....»»
Researcher creates algorithms to predict arsenic contamination in private wells
Despite the risks to human health, testing for arsenic isn't required for most private drinking wells in New Jersey. To help address this regulatory gap, a Rutgers researcher developed a machine learning model that can estimate arsenic contamination.....»»
Micro- and nano-plastics and arsenic combination intensifies toxic effect on submerged macrophytes
Micro- and nano-plastics (MP(NP)s) in the environment are concerning due to their large specific surface area, low surface polarity, and easy adsorption and accumulation of other pollutants. Submerged macrophytes, which are completely submerged in wa.....»»
Elevated levels of arsenic and other metals found in Nevada"s private wells
Outside of Nevada's bustling cities, private wells are the primary source of drinking water, serving 182,000 people. Yet some of the tested private wells in Nevada are contaminated with levels of heavy metals that exceed federal, state or health-base.....»»
Some plants can short-circuit the toxic effects of metals. Now scientists are trying to harness their power
At first glance, it's hard to see what gold, iron, lead, arsenic, silver, platinum and tin have in common. A look at the periodic table will clear up the confusion: they are all heavy metals, typically categorized as those metals with an atomic weigh.....»»
Study finds potentially dangerous levels of arsenic in California prison drinking water
Ten years after the state of California recognized the human right to water, hundreds of thousands of residents still rely on drinking water that contains dangerous levels of contaminants, including the highly toxic mineral arsenic. Many of them live.....»»
Adsorbent material filters toxic chromium, arsenic from water supplies
Researchers at the Department of Energy's Oak Ridge National Laboratory are tackling a global water challenge with a unique material designed to target not one, but two toxic, heavy metal pollutants for simultaneous removal......»»
Arsenic in private well water contributes to low birth weight even at low levels
In the largest epidemiologic study of arsenic and birth outcomes to date, researchers from the University of Illinois Chicago and collaborating institutions estimated arsenic levels in U.S. private well water sources by county and compared estimates.....»»
Arsenic helps make black phosphorus stable for energy efficiency
The quest for thermoelectric materials that efficiently convert changes in temperature into electric voltage is challenging. For optimal performance, a material must conduct small amounts of heat and large amounts of electricity. However, crystal str.....»»
