The effect of positively and negatively charged air ions on aerosols of SERRATIA MARCESCENS was evaluated by comparing rates of exponential bacterial decay. Ions of both polarities were responsible for significant increases in the mean exponential decay rates when compared with a non-ionized ambient atmosphere. Negative ion atmospheres were shown to be slightly more active than positive ion atmospheres,which is probably due to a greater biological action of negative ions.
