abstract

Laboratory measurements demonstrating the effects of ozone on aerosolized B. thuringiensis , as revealed by fluorescence spectra, are reported. The fluorescence emission peak around 330 nm (excited at 263nm) decreases somewhat in intensity and becomes slightly blue-shifted. Further, the fluorescence emission around 400 nm-550 nm is less affected by the ozone than is the 330 nm (tryptophan) peak.
