Arsenic In Rice Could Chromosomal Damage
2013-07-22 17:58:39

Lee Rannals for redOrbit.com - Your Universe Online According to a new study published in the journal Scientific Reports, rice could raise the risk of genetic damage in humans. Researchers discovered that high concentrations of arsenic in rice could cause chromosomal damage. They found that people in rural West Bengal eating rice  with greater than 0.2 mg/kg arsenic as a staple showed higher frequencies of micronuclei than those consuming rice with less arsenic. The study screened...

Apple Juice Arsenic Limits Set By The FDA
2013-07-12 12:18:24

Lee Rannals for redOrbit.com - Your Universe Online On Friday, the FDA proposed setting a new limit on the level of arsenic allowed in apple juice after facing public pressure from consumer groups over the past year. The agency proposed a limit of 10 parts per billion (ppb) for inorganic arsenic in apple juice, which is the same level set by the US Environmental Protection Agency (EPA) for arsenic in drinking water. "The FDA is committed to ensuring the safety of the American food...

There is a lack of evidence regarding the effectiveness of technologies used to reduce arsenic contamination finds research in BioMed Central's open access journal Environmental Evidence. More studies assessing the technologies themselves and how they are used in the community are needed to ensure that people have access to safe, clean water. Arsenic is now recognized to be one of the world's greatest environmental hazards, threatening the lives of several hundred million people. Naturally...

Human activities are not the primary cause of arsenic found in groundwater in Bangladesh. Instead, a team of researchers from Lawrence Livermore National Laboratory, Barnard College, Columbia University, University of Dhaka, Desert Research Institute and University of Tennessee found that the arsenic in groundwater in the region is part of a natural process that predates any recent human activity, such as intensive pumping. The results appear in the March 4 edition of the Proceedings...

Scientists identified aromatic rice with very low arsenic content and higher concentrations of essential nutrients, selenium and zinc -- published in Biomedical Spectroscopy and Imaging Millions of people worldwide are regularly exposed to arsenic through drinking water and eating rice grown in soil and water containing high amounts of arsenic. Long-term exposure can lead to the development of different types of cancer as well as serious cardiovascular, neurological, and other health...

A new way of making crystalline silicon, developed by U-M researchers, could make this crucial ingredient of computers and solar cells much cheaper and greener. Silicon dioxide, or sand, makes up about 40 percent of the earth's crust, but the industrial method for converting sand into crystalline silicon is expensive and has a major environmental impact due to the extreme processing conditions. "The crystalline silicon in modern electronics is currently made through a series of...

Semiconductor Nanoflowers Hold Promise For Energy Storage And Solar Cells
2012-10-12 05:29:59

April Flowers for redOrbit.com - Your Universe Online A research team from North Carolina State University has created flower-like structures out of germanium sulfide (GeS), which is a semiconductor material. The GeS flowers have extremely thin petals, 20-30 nanometers thick, with an enormous surface area. These flowers hold promise for next-generation energy storage devices and solar cells. “Creating these GeS nanoflowers is exciting because it gives us a huge surface area in...
