No. 52 - Environmental Tobacco Smoke - Estimation of its Contribution to Respirable Suspended Particles - Method based on Solanesol Determination

(CRM developed into ISO 18144)

Jan. 2002

Respirable suspended particles (RSP), a necessary indicator of overall air quality, emanates from many sources, such as combustion processes (including tobacco smoke), atmospheric dust, talc, insecticide dusts, viruses, bacterias, etc.. Consequently, RSP is an inappropriate tracer of environmental tobacco smoke (ETS) levels present in any environment and solanesol has been found to be a more selective marker to determine the contribution of tobacco smoke to RSP. This method apportions RSP into ETS and non-ETS components by determining the weight ratio of solanesol to total RSP.
