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 Sources and influencing factors Sources for indoor environments.

The book presents up-to-date coverage of methods for sampling and analysis, as well as various approaches to the investigation of health problems caused by exposure to biological contaminants in indoor air 2008-07-15 2015-12-01 a new approach for monitoring bioaerosols in Ireland. The core of the scientific programme exploits a recently developed spectroscopic technique designed to detect, characterise and quantify biological particulate matter in real-time. The data acquired are compared to results obtained from traditional offline techniques.

The samples taken were linked to specific activities likely to generate compost bioaerosols, such as turning and screening, and samples were collected from as close as possible to the source of emission. SKC offer a range of products for bioaerosol sampling, for investigating fungi, endotoxins, bacteria, pollen and fibres, whether airborne or on surfaces.
