| چکیده انگلیسی مقاله |
With the development of new technologies, the synthesis of silica and its use in chromatography columns and nanoparticles are increasingly used in various industries. Although these technologies have many advantages, they may have negative effects on humans and the environment. Regarding the biological environmental applications of nanoparticles, it is possible to refer to cases such as removing water, sewage, air pollution and use in environmental devices such as sensors and green nanotechnology such as reducing greenhouse gases. Apart from being useful, nanoparticles can create risks for the environment, humans and animals from the beginning of production to the time of waste disposal. For this reason, it is necessary to evaluate the environmental risks of nanoparticles during the life cycle of nanoparticles. In this article, first, some of the most important environmental features of nanoparticles, such as the mechanism of movement and transfer in the environment, facilitating the transfer of other toxic substances by nanoparticles, microbial biotoxicity of nanoparticles, biological degradation of nanoparticles, bioavailability, bioaccumulation, concentration in the environment And the absorption of nanoparticles has been studied. Then the environmental hazards of nanoparticles, the way of producing toxicity in the environment, the mechanisms of toxicity of nanoparticles and their environmental hazards have been studied. |
