Résumé

This chapter discusses the ecotoxicology of nanomaterials (NMs), including that of engineered nanomaterials (ENMs) and engineered nanoparticles (ENPs), and the impact of nanotechnology on different ecosystems. Ecotoxicology is a multidisciplinary field that integrates toxicology and ecology and studies the effects of toxic chemicals on biological organisms. This approach predicts the effects of NMs on organisms to identify the most efficient and effective action to prevent or remediate any detrimental effect. The chapter describes some important recent research outcomes on the ecotoxic effects of some ENPs. Current understanding about the mechanisms of genotoxicity of nanoparticles is predominantly based on genotoxicity investigations performed with the particulate carcinogen quartz and poorly soluble particles of low toxicity such as carbon black and titanium dioxide. The chapter also describes common tests used in current genotoxic study of ENPs.
