“…51,52 Solanesol has also been identified as an ETS particulate marker. 53,54 Vegetative sources other than tobacco can contribute to solanesol. If these sources are important, they must also be taken into account in source apportionment.…”

Fine particulate matter is believed to be more toxic than coarse particles and to exacerbate health problems such as respiratory and cardiopulmonary diseases. Specific organic compounds within atmospheric fine particulate material can be used to differentiate specific inputs from various emissions and thus is helpful in identifying the major urban air pollution sources that contribute to these health problems. Particular marker compounds that carry signature information about different emission sources (i.e., gasoline or diesel motor vehicles, wood smoke, meat cooking, vegetative detritus, and cigarette smoke) are reviewed. Aerosol organic types (e.g., from mass spectrometry data, which can also help in elucidation of carbonaceous material sources) are also discussed. Apportionment of the primary source contributions and atmospheric processes contributing to fine particulate matter and fine particulate organic material concentrations are outlined. This review provides an overview of the latest developments in chemical characterization approaches for identification and quantification of compounds in complex organic mixtures associated with fine atmospheric particles and their use in chemical mass balance (CMB) and positive matrix factorization (PMF) source apportionment models.

“…We selected tobacco specific markers of the particulate and the vapor phase of ETS. No sources of airborne solanesol have been reported; it is specific to tobacco combustion and regarded as probably the best marker for the particulate matter of ETS (15). UVPM and FPM have been shown to track the particulate phase of ETS well and have been used in many studies, both in personal ETS monitoring and in area sampling of ETS.…”

SUMMARYThis substudy of a randomized, controlled, forced switching, open-label, parallel-group clinical study in a total of 100 healthy adult male and female smokers compared environmental tobacco smoke (ETS) produced from smoking a second generation electrically heated cigarette smoking system (EHCSS), two conventional cigarettes, and no-smoking. Concentrations of air constituents including respirable suspended particulate matter (RSP), carbon monoxide (CO), and total volatile organic compounds (TVOCs) and ETS markers including solanesolrelated particulate matter (Sol-PM), ultraviolet absorbing particulate matter (UVPM), fluorescing particulate matter (FPM), nicotine and 3-ethenylpyridine (3-EP) were measured in a ventilated, furnished conference room over a period of 2 hours on separate occasions. Except for TVOCs, concentrations of air constituents and ETS markers were reduced by 40% to more than 90% when adult smokers were smoking the EHCSS as compared to smoking conventional cigarettes. CO and most ETS marker concentrations were in the same range as nosmoking. [Beitr. Tabakforsch. Int. 23 (2008)

“…Tang et al (1990) reported that solanesol is a suitable tracer component even in environmental tobacco smoke. Therefore, solanesol in the particles is expected to be generated immediately by homogenous and/or heterogenous nucleation within a short distance (<10 mm) at the top of the cigarette after burning.…”

Tobacco columns are extreme examples of heterogenous packed beds, which have various cut-filler shapes and a wide range of size distribution. The behavior of mechanical filtration through tobacco columns has been investigated by using polystyrene latex (PSL) standard particles to compare the actual filtration efficiency with the predicted filtration efficiency calculated by theoretical equations for spherical packed beds. The influence of cut-filler shape and the range of cut-filler size distribution on filtration efficiency have been examined. The effect of diffusion in tobacco columns was lower and the effect of interception and inertia were higher than in spherical packed beds. These results show that a partially faster flow could have occurred in tobacco columns. It means that it is difficult to utilize the theoretical equations for spherical packed beds to heterogenous packed beds as proposed. Filtration efficiency through tobacco columns had a relationship with the factor that shows cut-filler shape and size distribution (r D 0.894, p < 0.05) and the factor that shows cut-filler size distribution (r D 0.683, p < 0.15). The factor showing cut-filler shape and size distribution was expected to be an effective factor of filtration efficiency for heterogenous packed beds. From these experiments, empirical equations that can be applied to tobacco columns have been proposed, and the prediction accuracy during burning was validated. It has been found that the prediction accuracy was precise, revealing the importance of taking the influence of cut-filler shape and size distribution into account in the filtration equations.
