The Influence of Silver Nanoparticle Form on the Toxicity in Freshwater Mussels

The contribution of the form silver nanomaterials (nAg) towards toxicity in aquatic organisms is not well understood. purpose this study was to examine various structures (sphere, cube and prism) nAg Dreissena bugensis mussels. Mussels were exposed increasing concentrations polyvinyl-coated same size for 96 h at 15 °C. They then analyzed biophysical changes cytoplasm (viscosity, protein aggregation lipids), neuro-activity (fractal kinetics acetylcholinesterase (AChE)), oxidative stress (labile zinc (Zn) lipid peroxidation) inflammation (arachidonate cyclooxygenase). Although some decreasing effects observed, viscosity more strongly decreased mussels spheric prismatic nAg. activity AChE significantly following form-dependent manner: > cubic fractal dimension reactions reduced by all geometries nAg, while dissolved Ag had no effects. For nanoparticles with coating relative size, produced significant AChE, increased both viscosity, whereas cytoplasm. It concluded that could influence organisms.
