Paper 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.
