存在于空气中的几种大小不等的微小生物称为气载颗粒物或生物气溶胶，主要包括活的或死的真菌和细菌及其次级代谢产物、病毒、花粉等，它们与人类和其他生命种群的健康问题有关。2001年的生物恐怖袭击以及2009年由甲型H1N1流感病毒引起的流感大流行使我们对生物气溶胶研究的重要性感到震惊。因此，有必要对各种室内环境中的不同空气微生物进行表征，即识别和量化，以识别相关风险并确定接触阈值。沿着生物气溶胶的采样和分析技术，揭示了生物气溶胶的浓度水平的各种文献已经提到在这篇综述中，从而有助于识别和定量的知识，生物气溶胶及其不同成分在各种室内环境（包括职业和非职业部分）。除了对生物气溶胶的认识外，其控制机制的发展也起着重要作用。因此，几种控制方法也进行了简要审查。然而，几个单独的层面的努力，如定期清洁操作，维护活动和适当的通风系统，也有助于改善室内空气质量的最佳方式。生物气溶胶的分布高度依赖于季节，夏季和秋季较高，冬季最低。撞击法虽然是最常用的方法，但由于存在过载问题，不适用于高污染环境。在所有计数技术中，显微技术主要用于生物气溶胶的鉴定。在生物气溶胶引起的许多疾病中，非典型肺炎和结核病是造成最大社会经济影响的疾病。有许多控制机制，但混合机制（不同方法的组合）是最有效的。
Several tiny organisms of various size ranges present in air are called airborne particles or bioaerosol which mainly includes live or dead fungi and bacteria, their secondary metabolites, viruses, pollens, etc. which have been related to health issues of human beings and other life stocks. Bio-terror attacks in 2001 as well as pandemic outbreak of flue due to influenza A H1N1 virus in 2009 have alarmed us about the importance of bioaerosol research. Hence characterization i.e. identification and quantification of different airborne microorganisms in various indoor environments is necessary to identify the associated risks and to establish exposure threshold. Along with the bioaerosol sampling and their analytical techniques, various literatures revealing the concentration levels of bioaerosol have been mentioned in this review thereby contributing to the knowledge of identification and quantification of bioaerosols and their different constituents in various indoor environments (both occupational and non-occupational sections). Apart from recognition of bioaerosol, developments of their control mechanisms also play an important role. Hence several control methods have also been briefly reviewed. However, several individual levels of efforts such as periodic cleaning operations, maintenance activities and proper ventilation system also serve in their best way to improve indoor air quality. Bioaerosol distribution is highly dependent on seasons and is found to be higher in summer and fall and lowest in winter. Impaction though mostly used but is not suitable for highly contaminated environment due to overloading problem. Among all the enumeration techniques microscopic technique has been mostly used for bioaerosol identification. Among many diseases caused by bioaerosols SARS and tuberculosis are diseases that cause maximum socio-economic impacts. There are many control mechanisms but hybrid mechanism (combination of different methods) is the most efficient.
