supplements, additives or nutrients. Nanotechnology may be used to produce packages with improved mechanical and thermal properties, while nanosensors may be incorporated in the packaging systems to alert consumers if a food product is no longer safe to eat. Nanotechnology may also be used to produce more healthy foods. In contrast to beneficial effects and potential use of engineered nanotechnology materials (ENMs), which are very well described, there is a lack of knowledge about potential (eco) toxicological effects of nanoparticles. This is a one of the reasons which is there are many concerns over consequences of nanoparticles use for human and also environmental health. ENMs contain many different substances, in many forms and sizes and with a variety of surface coatings. The health assessment of such diverse materials is complex process and requires validated analytical methods both for their characterization. It is important not only to determine their presence and concentration in bulk samples, but in workplace air as well, because this is one of the most important ways of nanoparticles entrance into human body. In order to evaluate the risk of exposure to nanoparticles, several parameters including size and shape, crystalline form, functionalisation and purity should be considered
