The aim of this study is to determine the in vitro vs. in vivo dose-response relationships. A549 cell were grwon in the air-liquid interface and exposed to NO2, SO2, formaldehyde and ozone. The results are measured in cytotoxicity (viability) and genotoxicity (COMET assay). The project has proved satisfying. transferability of the test method.
