  Abstract:  Numerous examples of modern technologies and many latest research areas in use today are based on nanomaterials and nanoparticles. At the same time, it is accepted that their applications may raise new safety challenges for the reason that many materials properties may change radically at small length scales primarily due to the increased surface to volume ratio. The increased development and use of nanoparticles in industries could lead to increased exposure, which may possibly have a strong influence upon the human health and the environment. The biological behaviour of nanoparticles is induced by the chemical composition and for this reason the human exposure to airborne nanoparticles within workplaces and laboratories along with the environment contact with these materials should be permanently controlled in order to prevent bioaccumulation.
