Bioaerosol Sources, Sampling Methods, and Major Categories: A Comprehensive Overview

Bioaerosols are aerosols with biological traces. Recently, based on analytical methods for obtaining biological information, it has been shown that bioaerosols play an important role in the climate change as well as the reproduction and spread of organisms across various ecosystems, they also have biological effects in organisms, including humans. In particular, the nature of bioaerosols has been determined by next-generation sequencing and scanning electron microscopy. Here, we provide a comprehensive overview of the sources of bioaerosols, the sampling methods and the technologies used for their investigation. Furthermore, this review discusses the preexisting knowledge about the major categories of biological aerosol particles. This review will provide information on bioaerosols for the beneficial application of this information in future works.
