Ti,O particle aggregates

A paper published by CEINT researchers collaborating at Virginia Tech and Duke has made the list of top ten accessed articles from the online version of the Journal of Environmental Monitoring, during the month of March.
Characterization and environmental implications of nano- and larger TiO2 particles in sewage sludge, and soils amended with sewage sludge was authored by Bojeong Kim, Mitsuhiro Murayama, Benjamin P. Colman and Michael F. Hochella (J. Environ. Monit. DOI: 10.1039/C2EM10809G).
The CEINT funded team researched the most extensively used engineered nanoparticle to date, Titanium dioxide (TiO2), and showed that TiO2 nanoparticles from biosolids can interact with toxic trace metals that would then enter the environment as a soil amendment. The long-term behavior of TiO2 nano- and larger particles in sewage sludge materials as well as their impacts in the soil environment needs to be carefully considered.
