The developmental toxicity of silver nanoparticles (AgNPs) was investigated following exposure of Oryzias latipes (medaka) embryos to 0.1-1 mg/L of homogeneously dispersed AgNPs for 14 days. During this period, developmental endpoints, including lethality, heart rate, and hatching rate, were evaluated by microscopy for different stages of medaka embryonic development. To compare toxic sensitivi...
Guidelines for developmental toxicity studies require that the highest dose(s) should induce some signs of maternal toxicity. However, the interpretation of the results is often difficult when developmentally toxic effects are recorded only at maternotoxic doses, as it is impossible to ascertain whether the developmental effects are maternally mediated or not. In order to avoid this source of m...
