Aerosol Deposition measurement. ZnO was quantified by atomic absorption spectroscopy, taking advantage of the solubility of zinc in acetic acid. A ZnO mass deposition of 1.3 – 6.1 μg/cm2 was measured in the range of 22 – 90 sec reactor runtime, used for subsequent biological experiments. Points indicate individual measurements, bars and whiskers show mean values and standard deviation. Please note the interrupted axis.
