Porewater collection and soil extractions with 0.01 M CaCl2, 0.4 M Glycine (pH 1.5) and 0.05 M NH4-EDTA were performed. The effect on soil exoenzyme activities was also assessed. Porewater concentration was low (<0.4% and <0.04% of dosed Ag, for AgNPs and PVP-AgNPs, respectively) and only detected in acidic soils (pH 4.4 and 4.9). The PVPcoating reduced the downward mobility of AgNPs in soil and possibly also their dissolution rate (and subsequent release of dissolved Ag+ ions into porewater). The effect of variation in organic matter on soil enzymatic activity was larger than that of AgNPs, as no significant additional inhibitory effect from Ag could be observed. Only at low pH and in the presence of complexing ligands that form very stable Ag complexes (0.4 M Glycine extraction at pH 1.5) up to 58% of the Ag added to soil was released (independently of PVP coating). An extraction with glycine is proposed as a useful indicator of potentially available Ag in soilsMDPIRepositório da Universidade de LisboaCruz, Nuno C.Farto, MárciaMourinha, ClarisseTavares, DanielaDuarte, Armando C.Trindade, TitoPereira, EduardaRomkens, Paul F.A.M.Alvarenga, PaulaRodrigues, Sónia M.2021-05-27T14:45:26Z20212021-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.5/21369engCruz, N.C.; Farto, M.; Mourinha, C.; Tavares, D.; Duarte, A.C.; Trindade, T.; Pereira, E.; Römkens, P.F.A.M.; Alvarenga, P.; Rodrigues, S.M.
