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.
苜蓿根瘤菌102F5在20℃气溶胶中的存活情况是,在高相对湿度(RH)下存活率最高,在低相对湿度下存活率最低。在50%相对湿度的气溶胶中,需要相对高浓度的二氧化氮(NO₂)、二氧化硫(SO₂)或甲醛才能显著降低苜蓿根瘤菌的活力。除了二氧化硫对甲醛活性的降低作用外,混合污染物没有相加或拮抗作用。高环境相对湿度增强了二氧化氮和二氧化硫的杀菌活性。高相对湿度使300至400纳米波长紫外线的生物效应最小化,而低相对湿度则使其增强。
