Stationary source emissions - Bioaerosols and biological agents - Sampling of bioaerosols and collection in liquids

Scope

The proposed deliverable based on the German VDI Standard 4257 Part 2 contains specifications for active sampling of bioaerosols from exhaust air flowing through a defined cross-section of a stack. It defines general principles that have to be taken into account during an isokinetic sampling of bioaerosols under application of an emission impinger. Separation of microorganisms in the impinger designed for a sample volume flow of 1 m3/h to 1,8 m3/h, or 16 l/min to 30 l/min, respectively, and has been tested with regard to various microorganisms with broad concentration ranges.
