The Fate of Silver Nanoparticle Waste
Manufacturers have incorporated silver nanoparticles into more than 200 consumer products, including clothing and cosmetics, because of their antibacterial properties. Now researchers analyzing sewer sludge provide the first evidence that silver leaching from these consumer products transforms into silver sulfide nanoparticles in wastewater treatment plants (Environ. Sci. Technol., DOI: 10.1021/es101565j). The findings provide scientists with important new information about the life . . .
