  • Analysis of ecotoxicological data across different trophic levels.

    • Main Results:

    • Ag NPs can affect prokaryotes, invertebrates, and fish at concentrations below predicted environmental levels.
    • Nanoscale-specific properties may contribute to toxicity beyond dissolved silver ions.
    • Significant knowledge gaps exist regarding Ag NP characterization and environmental monitoring.

    Conclusions:

    • Ag NPs present a poorly characterized but significant potential risk to aquatic ecosystems.
    • Methodological advancements are needed for accurate quantification of Ag NPs in the environment.
    • Further research into Ag NP mechanisms of toxicity and environmental behavior is recommended.
