Nanoparticles in wastewaters: hazards, fate and remediation

摘要: The increasing use of nanoparticles will inevitably result in their release into the aquatic environment and thereby cause exposure living organisms. Due to larger surface area, high ratio particle number mass, enhanced chemical reactivity, potential for easier penetration cells, may be more toxic than particles same substance. Some researchers have been showing some relations between certain diseases. However, doses, shapes, material toxicity persistence all factors determining harmful biological effects. In order better evaluate risks, route has taken consideration as well. Finally, a brief summary techniques nanoparticle removal waters wastewaters is presented, but it seems that no treatment can absolutely protect public from large-scale dissemination nanomaterials.
