Silver phytoavailability in exposure scenarios close to predicted environmental concentrations (PEC) has rarely been studied. The ISO-standardized RHIZOtest, based on a root mat technique, was used to expose tall fescue (Festuca arundinacea) to silver at a concentration close to 0.0015 mg kg?1 and 100 times higher (0.15 mg kg?1) than PEC in soils (the PEC of Ag nanoparticulate in the soil range ...
