TLDR
The ecotoxicological literature shows that concentrations of Ag NPs below the current and future PECs, as low as just a few ng L(-1), can affect prokaryotes, invertebrates and fish indicating a significant potential, though poorly characterised, risk to the environment.About:

Environmental transformations of silver nanoparticles: impact on stability and toxicity.
Clément Levard,Clément Levard,E. Matt Hotze,E. Matt Hotze,Gregory V. Lowry,Gregory V. Lowry,Gordon E. Brown,Gordon E. Brown,Gordon E. Brown +8 more
TL;DR: In this paper, the major transformation processes of Ag-NPs in various aqueous environments, particularly transformations of the metallic Ag cores caused by reactions with (in)organic ligands, and the effects of such transformations on physical and chemical stability and toxicity are discussed.

Toxicity of Ag, CuO and ZnO nanoparticles to selected environmentally relevant test organisms and mammalian cells in vitro: a critical review
Olesja Bondarenko,Katre Juganson,Katre Juganson,Angela Ivask,Kaja Kasemets,Monika Mortimer,Monika Mortimer,Anne Kahru +7 more
TL;DR: The toxic range of all the three metal-containing NPs to target- and non-target organisms overlaps, indicating that the leaching of biocidal NPs from consumer products should be addressed.

The bactericidal effect of silver nanoparticles
Jose Ruben Morones,Jose Luis Elechiguerra,A. Camacho,Katherine B. Holt,Juan B. Kouri,Jose Tapia Ramirez,Miguel Jose Yacaman +6 more
TL;DR: The results indicate that the bactericidal properties of the nanoparticles are size dependent, since the only nanoparticles that present a direct interaction with the bacteria preferentially have a diameter of approximately 1-10 nm.
