NANOMATERIALS: ORIGIN AND POTENTIAL ENVIRONMENTAL IMPACT

In recent years, research into the environmental impact of nanomaterials continues to be one of the main areas of interest. Nanomaterials, both natural and synthetic, are produced, transformed and exported around us daily. The annual influx of natural nanomaterials into the environment is about 97% of the total, and only 3% is synthetic nanomaterials. Currently, synthetic nanomaterials are widely used in various fields including chemistry, engineering, electronics and medicine, which contribute to the development of technology. However, a number of researchers express concern about the consequences of using nanomaterials in various aspects. And in this case, it is extremely important to understand their behavior in various environmental conditions, ways of influencing the ecosystem and human health. This article will consider: the sources of origin of nanoparticles, a number of positive and negative aspects of the potential impact of nanomaterials on the environment, as well as the importance of monitoring. Key words: nanomaterials, nanotechnologies, safety, protection, ecology, health, monitoring.
