Impairment of the respiratory epithelium caused by zinc oxide nanoparticle exposure?

Kai Fruth, Susanne Duca, Anne Hilliger, Wolf J. Mann & Juergen Brieger
Background: Zinc oxide (ZnO) nanoparticles are used in industrial products like wall paint, sunscreen, and are byproducts of combustion processes. An impairment of the respiratory epithelium by ZnO-nanoparticle exposure seems feasible. However, the exact mechanism of a potential cell damage has not [for full text, please go to the a.m. URL]
