Epidemiological studies on zinc oxide (ZnO) nanoparticles have not been available so far.


It is a fact, however, that inhalation of ZnO fumes during welding may cause metal fume fever [1,2]. Bearing the symptoms of influenza, this disease gets better after a few days but may impede lung function if exposure is continued. For all that, it is much more probable that, being used as physical UV filters in suncreams and in cosmetics, the ZnO nanoparticles are taken up via the skin.
