Abstract

Silver nanoparticles (AgNPs), as a new material with good properties, has been widely used in many fields. With the increasing production and usage of it, more and more AgNPs are entering the water environment, which was suspected to impose ecological risk to the aquatic ecosystem. Based on the acute aquatic toxicity data of AgNPs, this paper established the species sensitivity distributions (SSDs) curve of silver nanoparticles in water environment. Referring to the proposed method of establishing PNEC in Europe TGD, acute aquatic ecological threshold of AgNPs was calculated, and it is 7.35 g/L. This work attempts to provide a reference for the environmental impact assessment of silver nanoparticles. The results showed that current concentration of AgNPs in the water environment would have no significant toxic effects on aquatic organisms. However, the environmental impact of AgNPs still needs to pay more attention.
