Introduction
Environmental Tobacco Flue Gas (ETS) is an aerosol consisting of gas phase and particulate matter due to the difference in gas phase and particle properties
Different, resulting in the lack of correlation between the two, and thus accurately evaluate the indoor air environment, the level of tobacco smoke levels need to be measured on both phases are appropriate
In the ideal environment Tobacco flue gas marked with the conditions, the most critical one is the environmental conditions in a certain range,
The indicator must maintain a fairly stable proportional relationship with a contaminant or a class of contaminants (eg, suspended particles) (see reference [1]).
Note. All references cited in the bibliography are provided. For the purpose of providing information to users of this standard, the reference text in the standard text lists the
The source of the literature.
UV particles (UVPM) and fluorescent particles (FPM) meet this requirement, in a variety of ventilation conditions and sampling time with the smoke
(RSP) remained a constant proportional relationship. In contrast, nicotine (environmental tobacco flue gas aerosol gas phase
(ETS-PM) does not maintain a constant proportional relationship with the environmental tobacco smoke particles (see reference [2]).
Inhalable suspended particulates are a very important indicator of the overall mass of air, and it has a variety of sources, such as combustion products
Gas, dust, talc, insecticide dust, viruses, bacteria, etc. (see reference [3].) Thus, respirable suspended particulates are not rings
The study shows that in most of the indoor space allowed to smoke, the average only 50% of the smoke,
Or less respirable suspended particulates are derived from tobacco smoke (see references [4] to [7].) The assay method described in this standard is effective
Reducing the degree of uncontrollable deviations inherent in respirable suspended particulate matter as an environmental tobacco smoke marker method (see reference
[4] ~ [6], [8] ~ [13]).
Because the measured spectral absorption is not unique to the organic tobacco smoke granules, these methods are environmental tobacco smoke
(I.e., an over-high evaluation) of the effects of inhalable suspended particulates
Will significantly increase the measured value of the UV particles (see reference [14]), while the tendency of the fluorescent particles is less obvious, but not
Absolute exclusion of the existence of interference. In short, due to the existence of non-quantifiable interference, so these methods can only provide environmental tobacco smoke on the indoor
A reference to the effects of respirable suspended particulates, rather than absolute values.
