The raw mutagenicity data for experiments initiated with VOC + UV and NOx (Figure 1). The data are the number of mutant colonies (called revertants or rev) per petri plate of strain TA100 of Salmonella using the Salmonella (Ames) mutagenicity assay.
Rev hr-1 figures were normalized to to non-precursor VOC concentrations by determining the difference between initial and final precursor concentrations (e.g., the delta Hydrocarbon for each precursor), in micrograms carbon m-3 (see Table 1). This SOC yield was then used to subtract off product concentrations lost to the particle phase. The remaining concentration was then considered to be the Estimated Gas-Phase Product Concentration. Mutagenic potencies, in rev hr-1, were divided by the Estimated Gas-Phase Product Concentration, to give normalized mutagenicic potencies in rev m3 hr-1 mgC-1.
