Survival of aerosolized bacteriophage φX174 in air containing ozone–olefin mixtures

Abstract

SUMMARY The effects of ozone and ozonized olefins on aerosol survival of bacteriophage øX174 were studied. The ozone concentrations used were between 0 and 110 parts/10 9 , giving decay rates up to 0·03 min −1 . The olefins used were trans-2-butene and cyclohexene in concentrations of 500 parts/10 9 and 2·4 parts/10 6 , respectively. Olefins alone have no effect, whereas in combination with ozone, decay rates of 0·1 min −1 and higher were obtained. The results are discussed in relation to the viricidal effect of open air.
