Oxidative stress, histopathological and genotoxicity of copper oxide nanoparticles in Biomphalaria alexandrina snail.

ABSTRACT: Higher usage of copper oxide nanomaterials in industrial and biomedical fields may cause an increase of these nanoparticles in aquatic environments, which could have a detrimental ecological effect. Thus, the objective of this study was to evaluate the acute toxicity of copper oxide nanoparticles on the freshwater gastropod, Biomphalaria alexandrina. Transmission electron microscopy, x-ray diffraction analysis and UV-VIS spectrophotometer of CuO NPs revealed a typical TEM image and a single crystal structure with average crystallite size of approximately 40 nm also, a sharp absorption band was appeared. Following exposure to sub-lethal concentrations of CuO NPs (LC₁₀, 15.6 mg/l and LC_25, 27.2 mg/l), treated snails revealed a significant decrease (p < 0.05) in total an
