Oxidation of glycerol to dihydroxyacetone over highly stable Au catalysts supported on mineral-derived CuO-ZnO mixed oxide

Toxicity of the mixture of nanoparticles to algae–bacteria consortia in OECD media

“…39 Corresponding metal ion toxicity of ZnO and CuO nanoparticles has already been characterized. 40,41 In this direction, several authors have shown the significant toxicity of the metal oxide nanoparticles ZnO and CuO to aquatic organisms. The acute toxicity of ZnO nanoparticles (L(E)C 50 : 0.05–1000 mg l −1 ) and CuO nanoparticles (E(L)C 50 : 0.05–569 mg l −1 ) was already documented for bacteria, algae, protozoa, nematoda, crustacea, and fish.…”
