Aeromicrobiology is the study of living microbes which are suspended in the air. These microbes are referred to as bioaerosols (Brandl et. al, 2008). Though there are significantly less atmospheric microorganisms than there are in oceans and in soil, there is still a large enough number that they can affect the atmosphere (Amato, 2012).

Single aerosols, smaller than 10 μm, are interrogated with 266 nm and 355 nm laser pulses separated in time by 400 ns. Fluorescence signals excited by these pulses are detected in three broad spectral bands centered at 350 nm, 450 nm and 550 nm.

Bioaerosols have an impact on human health. Indoor and outdoor sources of bioaerosols are numerous and can derive from essential human activities such as farming and composting. Seasonal changes are also linked with modulation of airborne biological agents that have a significant impact on human health (e.g., pollens and spores) and means of monitoring and evaluating their impact is currently Besides direct health effects, bioaerosols also impact public health and ecology through their global transport and acting as ice nuclei (IN) and cloud condensation nuclei (CCN). Humans are facing increased threats of biological aerosol infections. Following its golden age in the 18th century, the bioaerosol Bioaerosols (short for biological aerosols) are a subcategory of particles released from terrestrial and marine ecosystems into the atmosphere.

The isolation of various microorganisms, including Staphylococcus, Escherichia, and Salmonella spp., from air samples and carcass swabs support the theory 2009-08-03 · Introduction to Bioaerosols and Their Dynamic Properties Aerosol: A suspension of small solid or liquid particles in a gas (usually air) Unit of size measurement for typical aerosols is the micrometer (µm) = micron (µ) = 10-6m Unit of concentration: ug/liter or mg/cubic meter Bioaerosols, or primary biological aerosol particles (PBAP), have a significant impact on the relationships between our atmosphere, climate, biosphere, and public health. Pollen, airborne bacteria, fungal spores, and other bioparticles have many roles in the Earth system. The reproduction and proliferation of organisms across ecosystems.

bioaerosols as are filters [Macher and Hansson 1987]. Impactors used for the collection of airborne microorganisms may have range from a single slit to more than 400 holes per stage. The particles impact onto growth medium with one or more bacterial or fungal colonies forming at some impaction sites. Multiple particles, each Atmospheric bioaerosols can exert direct and indirect effects on climate.

In the last module of course, we look into the two other major indoor air contaminants - Bioaerosols and Asbestos. Staying in a clean environment does not mean the environment is comfortable. "Thermal Comfort" is also an issue that we need to consider.
