Copper and copper oxide nanomaterials (nCuO) can enter the marine environment negatively impacting mussels, an environmental and commercially relevant organism. We analyzed the effects on the immune system of adult mussels exposed to soluble copper (CuSO4, 20‐50 μg/L) or nCuO (100‐450 μg/L). CuSO4 caused significant copper accumulation in gills and cell‐free hemolymph, while nCuO caused cell damage...
The toxicity of titanium dioxide nanoparticles (TiO2‐NP) in the blood, liver, muscle, and brain of a Neotropical detritivorous fish, Prochilodus lineatus, was tested. Juvenile fish were exposed to 0, 1, 5, 10, and 50 mg L−1 of TiO2‐NP for 48 hours (acute exposure) or 14 days (subchronic exposure) to evaluate changes in hematology, red blood cell (RBC) genotoxicity/mutagenicity, liver function (reactive...
