Anti-bacterial additive widespread in U.S. waterways
Many rivers and streams in the United Statesare believed to contain a toxic antimicrobial chemical whoseenvironmental fate was never thoroughly scrutinized despite large scaleproduction and usage for almost half a century, according to ananalysis conducted by researchers at the Johns Hopkins Bloomberg Schoolof Public Health. The chemical, triclocarban, has been widely used fordecades in han...Study: Soap And Water Work Best In Ridding Hands Of Disease Viruses
The largest, most comprehensive study ever done comparing the effectiveness of hand hygiene products shows that nothing works better in getting rid of disease-causing viruses than simply washing one’s hands with good old-fashioned soap and water. Among the viruses soapy hand washing flushes down the drain is the one that causes the common cold. Other removable viruses cause hepatitis A, ac...Unprecedented water level rise in Somalia
In East Africa, where days of heavy rains and flooding have led to numerous deaths and entire villages being wiped out, locals are reporting an unprecedented rise in Somalia's Shabelle River and that a major water surge may be headed into the centre of the country, the United Nations said today. According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), reports yesterd...Microbial fuel cell: High yield hydrogen source and wastewater cleaner
Using a new electrically-assisted microbial fuel cell (MFC) that does not require oxygen, Penn State environmental engineers and a scientist at Ion Power Inc. have developed the first process that enables bacteria to coax four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone. Dr. Bruce Logan, the Kappe professor of environmental engineeri...Survey finds silver contamination in North Pacific waters
The highest levels of silver contamination ever observed in the open ocean turned up in samples collected during a survey of the North Pacific in 2002. Researchers from the University of California, Santa Cruz, measured silver concentrations 50 times greater than the natural background level. Though still well below levels that would be toxic to marine life, this contamination of what had been co...Spatial Behavior System, Water Maze from myNeuroLab.com

According to a press release about one third the population of Bangladesh are at risk of getting cancer from arsenic deposits in well water. Drinking arsenic tainted water for prolonged periods results in skin lesions and cancer of kidney, skin, lung and bladder said the study.// At least 100,000 cases of debilitating skin lesions have already occurred, according to World Hea...UN Fears Melting Of Ice Would Concentrate Toxins in the Chinese Water Supply
The explosion at the chemical plan in the month of November released toxic substances contaminating the Chinese drinking water supply. This has created havoc in Russia also as they share the same water resources. // But the recent report given by the United Nations includes the danger of concentration of these chemicals due to the melting of the ice. It also mentioned the need for a regu...Drinking adequate amounts of water
Drinking enough amounts of water is very essential for an individual. One probably does not need to drink eight glasses of water a day, says a leading physiologist. We've been led to believe that we should drink about two litres of water a day that's eight glasses// of volume eight ounces (the 8 by 8 rule). But, water balance expert Dr Heinz Valtin of Dartmouth Medical School, there is no real s...US Autoflow Single Chamber Stackable Water-Jacketed CO2/O2 Inc.
