Nanoparticles are present in everyday life including industry, and this article focuses mainly on their occurrence in the work environment. We measured the concentration of nanoparticles in anthropogenic activity, where nanoparticles are generated as unwanted waste. Two plants were selected for such measurements. In the first plant we measured nanoparticles based on metals, while in the second we measured nanoparticles of organic origin, specifically wood. This article also deals with the possible toxic effect of nanoparticles on the environment. The procedures of ISO / TR 27 628 - workplace atmospheres - ultrafine, nanoparticle and nanostructured aerosols - inhalation exposure characterization and assessment were applied to identify the key sites in both plants that produced the largest number of nanoparticles. We suggest the provision of protective work funds in an environment with a risk of nanoparticles according to the certified methodology of the Ministry of Labour and Social Affairs.
