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. Direct effects are primarily based on the ability of bioaerosols to absorb and scatter light. The ability of aerosols to take up water at subsaturated conditions, i.e.
