Introduction
Environmental tobacco smoke (ETS) is an aerosol of gas and particulate matter. Due to the nature of the gas phase and particulate matter on the poor
Different, resulting in a lack of correlation between the two, and thus an accurate assessment of indoor air environment levels of tobacco smoke need to determine the two-phase are suitable
A Among all the conditions that an ideal environment tobacco smoke marker should have, the most critical one is that the environmental conditions are within a certain range
The mark must be fairly stable in relation to a contaminant or a type of contaminant such as suspended particulates (see reference text
Offer [1]).
Note. Bibliography lists all references cited.
Solanesol, a C45 isoprenoid alcohol, was found to be associated with respirable suspended particulate matter (VOC) of tobacco smoke at various aeration conditions and sampling times
To maintain a constant proportional relationship (see reference [2]), so to meet this requirement. According to ISO 15593 Determination of the UV particles and
Fluorescent grain phases are likewise the markers or markers that satisfy this requirement (see Reference [3]). But the unique characteristics of solanesol in the atmosphere
It is peculiar to tobacco smoke and exists only in the particulate phase of ambient tobacco smoke. Solanesol's high molecular weight and low volatility do not
May be missing from the sample collection membrane. Solanesol accounts for about 3% of the total mass of respirable suspended particulate matter in environmental tobacco smoke (see references
[4] to [6]). Such high levels are suitable for the measurement under the prevailing smoking prevalence rate. Tobacco smoke in available environment
Among the aerosol markers (UV-grainy, flourescent and solanesol), three are currently used and can be relied on, while solanesol is considered
Is a good marker for the environmental tobacco smoke particulate matter and is therefore also an assessment of environmental tobacco smoke particulates on respirable suspended particles
The best way to quantify the influence of matter (see references [7] ~ [15]).
Since respirable suspended particulates are not peculiar to tobacco fumes, tobacco smoke is quantified with tobacco-specific markers for absorbable
The impact of suspended particles is very important. Respirable suspended particulate matter is a very necessary measure of the overall air quality,
The U.S. Occupational Safety and Health Administration (OSHA) mandated that the maximum allowable level of inhalable dust in the workplace is 5000 μg/m
3. Of course
However, there are many sources of respirable suspended particulates (see reference [16]), which have proven unsuitable as markers for environmental tobacco smoke
(See references [4], [17] ~ [19]). Using UV Particles and Fluorescent Particles as Markers to Estimate Environmental Tobacco Smoke to Inhalable Suspensions
The impact of floating particles has a certain selectivity. However, these two markers are likely because of the potential interference with non-tobacco combustion
It will overestimate the impact of ambient tobacco smoke on respirable suspended particulates. Although the UV phase and the fluorescent particles phase on the test indoor empty
Gas quality is useful, but solanesol is a better marker for assessing the effects of tobacco smoke on respirable suspended solids. This standard describes
Test Methods By measuring the mass ratio of solanesol to total respirable suspended particulates, the sources of ambient tobacco smoke were compared to non-ambient tobacco smoke
(See references [4], [6], [10], [11], [14], [15], [20], [21]) from the source of inhalable suspended particulates.
Tobacco, one of which is tobacco, is a genus of solanaceous plants. Like tobacco, many plants in this family, especially traces
Nicotinic plants, all contain solanesol. For example, tomatoes, potatoes, eggplant and pepper. Cooking is the only possible source of interference, due to
This potential interference can be neglected. However, if there is such a source of interference, the amount of solanesol can be very high, and environmental tobacco smoke pairs
Inhalable suspended particles affect the determination of the results will be high. It is expected that the only source of normal solanesol in the indoor environment is smoke
Grass burning. In various indoor environments, solanesol concentrations ranged from undetected to 2 μg/m

Lower limit.

Estimation of Respirable Suspended Particulates in Environmental Tobacco Smoke
Solanesol method
1 Scope
This standard specifies the sampling and determination methods of environmental tobacco smoke (ETS) impact assessment of Respirable Suspended Particulate Matter (RSP). This
The method is suitable for both individual and regional sampling. The method and gravimetric determination of respirable suspended particulate matter quality, UV absorption and fluorescence
The method for the determination of RSP in ETS by UV spectrophotometry and fluorescent particle phase determination is the same.
Note. See GB/T 21131 for details.
This standard also specifies the method of estimating the composition of respirable suspended particles in the ambient flue gas --- solanesol assay.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1

3.3
Environmental tobacco smoke particulate part.
3.4
Estimates of the impact of environmental tobacco smoke particulate matter on respirable suspended particulate matter were obtained from measuring solanesol, a tobacco-specific compound.
4 principle
A known volume of air is pumped through an inert impactor or cyclone to separate particles above 4.0 [mu] m in size so as to be breathable
The suspended particulates are separated from the total suspended particulates, then the air is passed through a filter equipped with a Teflon filter, solanesol is inhaled
A component of floating particles that collects on the filter. The solanesol on the filter was extracted with methanol and the extract was injected into a UV detector
