The airborne microbiome is one of the relevant topics in ecology, biogeochemistry, environment, and human health. Bioaerosols are ubiquitous air pollutants that play a vital role in the linking of the ecosystem with the biosphere, atmosphere, climate, and public health. However, the sources, abundance, composition, properties, and atmospheric transport mechanisms of bioaerosols are not clearly understood. To screen the effects of climate change on aerosol microbial composition and its consequences for human health, it is first essential to develop standards that recognize the existing microbial components and how they vary naturally. Bioaerosol particles can be considered an information-rich unit comprising diverse cellular and protein materials emitted by humans, animals, and plants. Hence, no single standard technique can satisfactorily extract the required information about bioaerosols. To account for these issues, metagenomics, mass spectrometry, and biological and chemical analyses can be combined with climatic studies to understand the physical and biological relationships among bioaerosols. This can be achieved by strengthening interdisciplinary teamwork in biology, chemistry, earth science, and life sciences and by sharing knowledge and expertise globally. Thus, the coupled use of various advanced analytical approaches is the ultimate key to opening up the biological treasure that lies in the environment.
空气微生物群落是生态学、生物地球化学、环境和人类健康等领域的相关主题之一。生物气溶胶是普遍存在的空气污染物，在生态系统与生物圈、大气、气候及公共卫生的联系中发挥着至关重要的作用。然而，生物气溶胶的来源、丰度、组成、性质及大气传输机制尚未得到明确了解。为了筛选气候变化对气溶胶微生物组成的影响及其对人类健康的后果，首先必须制定标准，以识别现有的微生物成分及其自然变化情况。生物气溶胶颗粒可被视为一个信息丰富的单元，包含人类、动物和植物排放的各种细胞和蛋白质物质。因此，没有单一的标准技术能够令人满意地提取有关生物气溶胶的所需信息。为了解决这些问题，宏基因组学、质谱分析以及生物和化学分析可与气候研究相结合，以了解生物气溶胶之间的物理和生物关系。这可以通过加强生物学、化学、地球科学和生命科学等领域的跨学科团队合作以及在全球范围内共享知识和专业技能来实现。因此，综合运用各种先进分析方法是开启环境中生物宝库的最终关键。
