Figure 3From: Effects of flame made zinc oxide particles in human lung cells - a comparison of aerosol and suspension exposures Cytotoxicity assessed by measuring the release of intracellular lactate dehydrogenase in aerosol exposed samples. A cell lysate (“Triton”) served as positive control. No difference between incubator – and gas – control could be observed, indicating no influence of the exposure system on basal cytotoxicity. For all ZnO concentrations, elevated LDH levels were measured.Back to article page
