The bioaccumulation testing strategy for nanomaterials: correlations with particle properties and a meta-analysis of in vitro fish alternatives to in vivo fish tests
Autor: R. D. Handy, N. J. Clark, D. Boyle, J. Vassallo, C. Green, F. Nasser, T. L. Botha, V. Wepener, N. W. van den Brink, C. Svendsen
Publikováno v: Environmental Science: Nano, 9(2), 684-701
Environmental Science: Nano 9 (2022) 2
For manufactured nanomaterials (MNs), given the breadth of forms produced, it is not ethical or practical to test all materials using vertebrates. This study aimed to show how alternative methods could predict the in vivo bioaccumulation potential of
