【摘要】 归纳了有关气溶胶吸湿性的测量方法以及过去近30a来文献中报道的生物气溶胶吸湿性的主要研究成果,总结了不同种类生物气溶胶之间吸湿性的差异.已有研究表明,绝大部分的生物气溶胶粒子都具有一定的吸湿性,当相对湿度为90%时,吸湿增长因子约为1.04(真菌孢子)～1.22(细菌),花粉颗粒物吸湿后的质量与之前的比值为1.30～1.55.最后,提出了目前关于生物气溶胶吸湿性研究中尚未解决的科学问题及该领域的主要发展方向.更多还原

【Abstract】 This article introduces techniques used to investigate bioaerosol hygroscopicity,review hygroscopicity of bioaerosols reported in the last thirty years,and compares difference in hygroscopicity for various bioaerosols.Bioaerosols in general show moderate hygroscopicity:hygroscopic growth factors at 90% RH were found to vary between 1.04 for fungal spores and 1.22 for bacteria,and mass growth factors at 90% RH were found to be in the range of 1.30～1.55.Finally,we outline important questions which remained to be answered in this field and also propose some future research priorities.更多还原
