Air Sampling

In order to effectively monitor microbiological air quality, the nature of bioaerosols, as well as the parameters affecting air sampling and assaying techniques, need to be understood. In addition, the aim of the air sampling influences the choices of how the sampling and assaying are performed. There are plenty of different air sampling techniques based on different principles such as sedimentation, impaction, centrifugal force, filtration, and electrostatic precipitation. Each sampling method involves its intrinsic advantages and drawbacks. The selection of a bioaerosol assay method depends, for example, on speed, cost, labor, and knowledge level needed for the application. Bioaerosol results should not be directly compared to results from different samplers or assay methods
