(PhysOrg.com) -- Drinking water can transmit a number of diseases, including typhoid, dysentery, cholera, and diarrhea, which can then spread explosively throughout an entire service area. To avoid this problem, drinking water must be disinfected. After treatment and disinfection, the water is usually safe. http://www.physorg.com/news180767147.html Chemistry Wed, 23 Dec 2009 05:06:57 EST news180767147 (PhysOrg.com) -- Scientists have found that acidic ozone water can deactivate H1N1 viruses very effectively, offering a promising disinfectant for the millions of people trying to avoid the disease. Acidic ozone water (AOW) is made from regular tap water mixed with a small amount of acid such as hydrochloric acid, along with an ozonized gas that can be produced in the lab. After deactivating the virus, the substance eventually decays into plain water, leaving no residue or harmful materials in the environment. http://www.physorg.com/news176991361.html Chemistry Mon, 09 Nov 2009 12:18:10 EST news176991361 A small study has shown that people tend to believe that bottled water is somehow healthier than water from the tap. However, the research, published in the open access journal BMC Public Health, also shows that people are unsure exactly what these benefits might be and that they are rarely the main reason for choosing bottled. http://www.physorg.com/news164594046.html Space & Earth Fri, 19 Jun 2009 02:50:01 EST news164594046 Although most Americans take the safety of their drinking water for granted, that ordinary tap water could become deadly within minutes, says Prof. Abraham Katzir of Tel Aviv University's School of Physics and Astronomy. http://www.physorg.com/news161366997.html Physics Tue, 12 May 2009 17:10:49 EST news161366997 The convenience of fresh-cut produce, which includes packaged lettuces, has greatly increased sales despite multiple foodborne outbreaks associated with these products. To reduce these risks, strict hygiene programs and sanitizers are used for decontamination once the food is harvested. Preventing microbial contamination in the fields is equally important. Researchers from three institutions (Rutgers University, University of California, Davis and University of Arizona), lead by Jorge M. Fonseca at the University of Arizona's Yuma Agricultural Center, experimented with the use of harpin, a substance known to boost plants' resistance to disease, prior to harvest. http://www.physorg.com/news160650676.html Biology Mon, 04 May 2009 10:12:39 EST news160650676 As municipalities across the United States reduce their dependence on groundwater sources to mitigate environmental impacts like subsidence and flooding, there is a growing need for better purification processes to keep contaminants found in surface water sources out of the public tap. http://www.physorg.com/news159541848.html Chemistry Tue, 21 Apr 2009 14:11:43 EST news159541848 An X-ray-guided spinal tap procedure fails more than half of the time in young infants and should be used sparingly, if at all, for those patients, according to a new study done by researchers at Wake Forest University School of Medicine. http://www.physorg.com/news156619188.html Medicine & Health Wed, 18 Mar 2009 18:20:21 EST news156619188 Contact lenses increase the risk of infection with pathogenic protozoa that can cause blindness. New research, published in the November issue of the Journal of Medical Microbiology, shows that a high percentage of contact lens cases in Tenerife are contaminated with Acanthamoeba that cannot be killed by normal contact lens solution. http://www.physorg.com/news143712703.html Biology Mon, 20 Oct 2008 09:11:43 EST news143712703
