Abstract
Survival of
Rhizobium meliloti
102F5 in aerosols at 20 C was maximal at high relative humidity (RH) and minimal at low RH. Relatively high concentrations of NO
2
, SO
2
, or formaldehyde were needed to significantly reduce viability of
R. meliloti
in aerosols at 50% RH. Except for the reduction in activity of formaldehyde by SO
2
, there was no additive or antagonistic effect of mixing pollutants. High environmental RH enhanced bactericidal activity of NO
2
and SO
2
. High RH minimized and low RH accentuated the biological effect of ultraviolet light of 300 to 400 nm wavelength.
