The unique properties that nanoparticles exhibit, due to their small size, are the principal reason for their numerous applications, but at the same time, this might be a massive menace to the environment. The number of studies that assess the possible ecotoxicity of nanomaterials has been increasing over the last decade todetermine if, despite the positive aspects, they should be considered a potential health risk. To evaluate their potential toxicity, models are used in all types of organisms, from unicellular bacteria to complex animal species, In order to better understand the environmental consequences of nanotechnology, this review article aims to describe nanoparticles, define the environment, use nanoparticles in the environment, and evaluate their positive and negative effects on the environment and highlights the need for more intense and accurate development.
