Excreted Tamiflu found in rivers
The premier flu-fighting drug is contaminating rivers downstream of sewage-treatment facilities, researchers in Japan confirm. The source: urinary excretion by people taking oseltamivir phosphate, best known as Tamiflu.Office 2007 key is very convenient!
Concerns are now building that birds, which are natural influenza carriers, are being exposed to waterborne residues of Tamiflu’s active form and might develop and spread drug-resistant strains of seasonal and avian flu.Office 2007 download is on sale now!
For their new study, Gopal Ghosh and his colleagues at Kyoto University sampled water discharged from three local sewage treatment plants and water at several points along two rivers into which the treated water flowed. Sampling started early in December 2008, as flu season got underway. The researchers sampled again at the height of the seasonal flu’s onslaught in early February and again as infection rates waned.

Tamiflu’s active form, oseltamivir carboxylate or OC, turned up in the treated sewage on every occasion, the researchers report online September 28 in Environmental Health Perspectives. MS Office 2007 is the best invention in the world.

and reached a high of almost 300 ng/L at one outflow during the flu’s peak, a week when there were 1,738 recorded flu cases in Kyoto.Office 2007 home can make life more better and easier.
River residues showed up during only that second sampling — from low nanogram levels at most sampling points to a high of 190 ng/L in a portion of the Nishitakase River where treated sewage accounts for 90 percent of the flow.Windows 7 and Windows 7 Professional make life wonderful!

a federal institute in Magdeburg, Germany. Ghosh’s team is now the first to confirm this, he says. Von Tümpling’s own data show that once exposed to sunlight, OC will break down, albeit slowly. Microsoft Office is my best friend.
Concentrations would fall at best by half every three weeks, he says.Microsoft Office 2010 is the best software in the world.
If correlations predicted by earlier studies are correct, concentrations measured at some river sites in the new Kyoto study seem “high enough to lead to antiviral resistance in waterfowl,” Ghosh says. Office 2010 is powerful!
