Review of Source Apportionment Techniques and Marker Substances
To apportion personal exposures to sources of substances present in indoor and outdoor air through daily time-activity patterns is a highly complex task. This requires reliable exposure data and the application of source apportionment techniques to all kinds of microenvironmental samples (indoor, outdoor and commuting). The present report provides an overview of the existing source apportionment techniques and source tracers and their respective data requirements and serves as a background and guidance document for the development of harmonized exposure assessment practises.
