No. 51 - Environmental Tobacco Smoke - Estimation of its Contribution to Respirable Suspended Particles - Determination of Particulate Matter by Ultraviolet Absorbance and by Fluorescence
(CRM developed into ISO 15593)
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. The test methods described here have been used effectively to reduce the uncontrollable bias inherent in the use of RSP as a tracer of ETS.
