ABSTRACT
In the fi eld of nanotechnology, incorporation of nanoparticles into a wide variety of products including electronics, food, clothing, medicines, cosmetics and sporting equipment have potentially detrimental consequences for the producer, consumer and the environment. Epidemiological studies done in both adults and children, a positive correlation between the level of particulate air pollution and increased morbidity and mortality rates was found. In vivo and in vitro toxicological studies confi rm that low soluble and ultrafi ne particles are more toxic and infl ammogenic than the fi ne particles. However, as these particles are manufactured industrially, the term “ultrafi ne particle” has been replaced for nanoparticle (Stone et al. 2007).
