| Abstract |
Because of their unique properties, nano-sized metallic nanomaterials (NMs) have been used in extensive applications of biomedicine, electronics, optics, engineering, and personal care products. Accordingly, with increasing release of NMs into the environment, numerous studies of nanoecotoxicity have been conducted. Fish embryo toxicity test (FET) has many benefits in evaluating toxicity of NMs as an alternative to a whole-body test in fish. In this study, we collected and analyzed the toxicity studies of metallic NMs on freshwater fish embryos. Most studies have demonstrated that metallic NMs are highly toxic during the early development of fish embryos. However, it should be noted that the results for the same NMs on the same test species show variation due to differences in the size or surface properties of the test NMs and exposure conditions. For the safe use of metallic NMs, we need to analyze their effects based on their properties, test species, environmental media, and diverse conditions. |
