Nanotechnology Safety and Security

Abstract

Because of their unique characteristics, research and development of new nanomaterials is one of the major disciplines of the twenty-first century, and examining their special properties, especially toxicity, is therefore necessary. As well as their benefits (technological improvements, specific material properties, improved resistance to natural effects), new materials also bring new risks requiring assessment in terms of occupational health and safety and their abuse as potential biological carriers or other materials. The study presents general information about nanoparticles and their distribution and properties in relation to entering aquatic, soil, and atmospheric environments. The study describes and cites examples of measurements conducted on the exposure of different nanomaterials to the work environment. Risk assessments of nanomaterials according to the available methodologies, measures to protect against nanoparticles, and importantly, the abuse of nanoparticles as a potential threat to the CZ population are also described.
