Measurement methods and strategies for non-infectious microbial components in bioaerosols at the workplace.

Exposure to micro-organisms can be measured by different methods.
Traditionally, viable methods and light microscopy have been used for detection of micro-organisms.
Most viable methods measure micro-organisms that are able to grow in culture, and these methods are also common for the identification of micro-organisms.
More recently, non-viable methods have been developed for the measurement of bioaerosol components originating from micro-organisms that are based on microscopic techniques, bioassays, immunoassays and chemical methods.
These methods are important for the assessment of exposure to bioaerosols in work environments as non-infectious micro-organisms and microbial components may cause allergic and toxic reactions independent of viability.
It is not clear to what extent micro-organisms should be identified because exposure-response data are limited and many different micro-organisms and microbial components may cause similar health effects.
Viable methods have also been used in indoor environments for the detection of specific organisms as markers of indoor growth of micro-organisms.
At present, the validity of measurement methods can only be assessed by comparative laboratory and field studies because standard materials of microbial bioaerosol components are not available.
Systematic errors may occur especially when results obtained by different methods are compared. (...)
