Coresta Recommended Method N° 52 Environmental Tobacco Smoke – Estimation of Its Contribution to Respirable Suspended Particles – Method Based on Solanesol Determination

چکیده
Environmental tobacco smoke (ETS) is an aerosol that contains both vapor and particulate phase components. However, due to their nature, the two aerosol phases rarely correlate well. An accurate determination of ETS levels in indoor air, therefore, requires a proper tracer of both phases. One critical aspect of an ideal ETS tracer is that it should “remain in a fairly consistent ratio to the individual contaminant of interest or category of contaminants of interest (for example, suspended particulates) under a range of environmental conditions...” (see Ref. 3.1).

Second-hand smoke levels in UK pubs and bars: do the English Public Health White Paper proposals go far enough?
BACKGROUND The English Public Health White Paper proposes introducing smoke-free workplaces except in pubs and bars that do not prepare and serve food. The bar area will be non-smoking in exempted pubs. OBJECTIVE To explore the likely impact of these proposals in UK pubs and bars. METHODS A total of 59 pubs and bars within Greater Manchester in 2001 were chosen. Thirteen were mechanically v...
متن کاملDetermination of Tobacco Specific Nitrosamines in Cigarette Mainstream Smoke – Gc-tea Method
Between 1999 and 2005, a Task Force composed of CORESTA members has studied the existing methodologies for the determination of the Tobacco Specific Nitrosamines (TSNAs) in the mainstream smoke of cigarettes. Several methods have been proposed for this determination, which are mainly based on two types of analytical methodologies: GC-TEA (Gas Chromatography with a Thermal Energy Analyser as det...

متن کاملIdentification of oxidation products of solanesol produced during air sampling for tobacco smoke by electrospray mass spectrometry and HPLC.
Solanesol, a 45-carbon, trisesquiterpenoid alcohol found in tobacco leaves and tobacco smoke, has been used as a quantitative marker for tobacco smoke for years. However, solanesol appears to be unreliable as a quantitative marker for tobacco smoke during environmental air sampling because it can be degraded substantially when present as a component of tobacco smoke and by as much as 100% when ...
