Studies from Technical University in the Area of Environmental Science and Technology Described

June 6, 2014



By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Researchers detail new data in Environmental Science and Technology. According to news reporting originating in Garching, Germany, by VerticalNews journalists, research stated, "The majority of pure silver nanoparticles in consumer products are likely released into sewer systems and usually end up in wastewater treatment plants (WWTPs). Research investigating the reduction in nanoscale silver particles (n-Ag-Ps) has focused on the biological treatment process, generally in controlled laboratory experiments."

The news reporters obtained a quote from the research from Technical University, "This study, analyzing the field-collected samples from nine municipal WWTPs in Germany, is the first to evaluate the reduction in n-Ag-Ps by mechanical and biological treatments in sequence in WWTPs. Additionally, the concentration of n-Ag-Ps in effluent was determined through two different methods that are presented here: novel ionic exchange resin (IER) and cloud point extraction (CPE) methods. The n-Ag-Ps concentrations in influent were all low (

According to the news reporters, the research concluded: "Obviously, WWTPs are not potential point sources for n-Ag-Ps in the aquatic environment."
