In this work we tested the long term generation of ZnO-NPs for potential use in exposure experiments with laboratory animals. These experiments require the generation of NPs in the gas phase with appropriate number concentration (Nt>1 107 #/cm3) and geometric mean diameter (GMD<50 nm) in duration of several weeks. Several methods of gas phase ZnO-NPs synthesis using metalorganic precursors, such as zinc acetylacetonate, zinc tetramethylheptane dionate or diethylzinc were reported in the literature. However, NPs prepared from metalorganic precursor are usually more or less contaminated by elemental (EC) or organic (OC) carbon. Therefore we used metallic zinc as a precursor in this study.
