      abstract     = {It is considered inevitable that the increasing production
                      and application of engineered nanoparticles will lead to
                      their release into the environment. However, the behavior of
                      these materials under environmentally relevant conditions is
                      still only poorly understood. In this study the transport
                      and deposition behavior of engineered surfactant stabilized
                      silver nanoparticles (AgNPs) in water saturated porous media
                      was investigated in transport experiments with glass beads
                      as reference porous medium and in two natural soils under
                      various hydrodynamic and hydrochemical conditions. The
                      transport and retention processes of AgNPs in the porous
                      media were elucidated by inverse modeling and possible
                      particle size changes occurring during the transport through
                      the soil matrix were analyzed with flow field-flow
                      fractionation (FlFFF). A high mobility of AgNPs was observed
                      in loamy sand under low ionic strength (IS) conditions and
                      at high flow rates. The transport was inhibited at low flow
                      rates, at higher IS, in the presence of divalent cations and
                      in a more complex, fine-grained silty loam. The slight
                      decrease of the mean particle size of the AgNPs in almost
                      all experiments indicates size selective filtration
                      processes and enables the exclusion of homoaggregation
                      processes.},
