摘要

In Levard et al.,the toxicity of Ag~0 nanoparticles (NPs) is compared to the toxicity of partially sulfidized Ag~0/Ag_2S core-shell NPs for four different test organisms in eight exposure media, each having different chemical constituents. The lower observed toxicity of Ag~0/Ag_2S core-shell NPs compared to Ag~0 NPs is attributed to the lower concentration of dissolved Ag species in the exposure medium from sulfidation and/or the presence of chloride in the exposure medium. This correlation between toxicity and the dissolved Ag concentration was consistent across all organisms studied.
