Relative Contributions of Copper Oxide Nanoparticles and Dissolved Copper to Cu Uptake Kinetics of Gulf Killifish (Fundulus grandis) Embryos
Autor: Heileen Hsu-Kim, Benjamin T. Castellon, George R. Aiken, Chuanjia Jiang, Cole W. Matson
Publikováno v: Environmental Science & Technology. 51:1395-1404
The toxicity of soluble metal-based nanomaterials may be due to the uptake of metals in both dissolved and nanoparticulate forms, but the relative contributions of these different forms to overall metal uptake rates under environmental conditions are
