Semi‐volatile organic compounds (SVOC), such as di‐2‐ethylhexyl phthalate (DEHP), not only cause chemical sensitivity but can also trigger asthma. SVOCs are adsorbed onto airborne particles as well as gas‐phase molecules in indoor air, owing to their low vapor pressure. Therefore, 3 models are suggested to evaluate partitioning between the gaseous and particulate phases using data from previous studies. In this study, the characteristics of each model were extracted, and the mechanisms of DEHP adsorption onto test airborne particles were investigated under controlled temperature, airborne test particle concentration, and air exchange rate conditions in a chamber. The total DEHP concentration increased from 1.6 to 25.6 μg/m3 as the chamber temperature increased from 15 to 35°C. However, the particulate DEHP ratio φ decreased with the increase in temperature. The high airborne particle concentration caused an increase in the particulate DEHP concentration. Moreover, the estimates based on the Junge model corresponded well with the results of these experiments, whereas the Mackay and Pankow models overestimated the values of φ compared to the results of these experiments. These results indicate that particulate surface concentration is related to the DEHP adsorption mechanism onto airborne particles.

“…The same applies to PAH sampling methods based on Tenax adsorbents proposed by Wauters et al (2008) and Lazarov et al (2013), in which the flow rate was 0.1 L min -1 and 0.098-0.254 L min -1 , respectively.…”

“…In summary, the combined filter-adsorbent cartridge sampler allows to collect the total amount of PAHs in the air, but these adsorbent materials have some limitations that should not be neglected: the clean-up and the extraction of both PUF and XAD require a large consumption of time and solvents (in order to overcome this problem, solvent bubbling has been proposed; Portet-Koltalo et al, 2011); if adsorbents are reused, there are serious risks of contamination (thermally regenerable adsorbents, such as polydimethylsiloxane and Tenax™ might be a possible solution to this problem, as highlighted by Liu et al (2001b), Wauters et al (2008) and Lazarov et al (2013). Moreover, adsorbent cartridges are bulky compared to filters, and difficult to be used in personal and automated samplers.…”

The sampling of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere is often performed on filters, which retain only aerosol particles, disregarding the vapor fraction; after the filter, an adsorbent (e.g., polyurethane foam, PUF, or styrene/divinylbenzene, XAD) is sometimes used for sampling vapors not retained from the filter. However, the use of an adsorbent may lead to many disadvantages: contaminations, analysis time and costs, and size problems when developing automated or personal samplers. In this work, a functionalized glass fiber filter for the simultaneous sampling of aerosol particles and vapor fraction is presented for the sampling of PAHs in air. A low sampling efficiency was observed for 3 ring PAHs, but all carcinogenic PAHs (according to IARC) were totally retained on functionalized filters. On the other hand, a comparison with normal filter sampling was performed, and results obtained confirm that > 10% of benzo(a)pyrene can be lost from normal filters. Together with size reduction, another advantage of the functionalized filter is an enhancement in the extraction and purification recovery.

“…LVS sampling time can be much shorter (30min-2h) if coupled with thermal desorption (TD) technique. This is because that the TD method can achieve much better limits of detections than the traditional solvent extraction methods (Tienpont et al 2000, Aragón et al 2013, Lazarov et al 2013. The advantages of TD method over solvent extraction method will be discussed in the following section.…”

“…Application of the conventional methods is generally restricted by the potential contaminations in the extraction/cleaning up process, poor detection limits, time-and-labor intensity (Urbanowicz et al 2011). Small volume air sampling followed by thermal desorption (TD) extraction and GC/MS analysis has been applied to indoor airborne phthalate sampling and analysis in some previous studies (Tienpont et al 2000, Lazarov et al 2013. As discussed in Section 2.4, the TD method owns a number of advantages over the conventional solvent extraction methods such as better detection limits, less potential of environmental contamination, time-and labor-savings as well as better recovery (Urbanowicz et al 2011).…”

would like to express my sincere gratitude to those who have accompanied and continuously support during my PhD study. I am deeply indebted to my advisor Victor Wei-Chung Chang, who always tries his best to help and encourage me during my study. He always tries to train me to be a well-prepared researcher for the future. Victor also offers me opportunities to try different things, to think and learn independently, and to make mistakes. I believe that his training will benefit my future career greatly. I thank my undergraduate mentor, Ma Shijun, who always encourages me to pursue my dream and teaches me to treat life and things in peaceful and rational manners.
