Risks, Release and Concentrations of Engineered Nanomaterial in the Environment.

ABSTRACT: For frequently used engineered nanomaterials (ENMs) CeO₂-, SiO₂-, and Ag, past, current, and future use and environmental release are investigated. Considering an extended period (1950 to 2050), we assess ENMs released through commercial activity as well as found in natural and technical settings. Temporal dynamics, including shifts in release due to ENM product application, stock (delayed use), and subsequent end-of-life product treatment were taken into account. We distinguish predicted concentrations originating in ENM use phase and those originating from end-of-life release. Furthermore, we compare Ag- and CeO₂-ENM predictions with existing measurements. The correlations and limitations of the model, and the analytic validity of our approach are discuss
