“…Some of the researches have also focused upon the assessment of natural versus anthropogenic contributions to the carbonaceous aerosol by searching molecular markers or tracers (Abas et al 1995, b, Alves and Pio, in press, Cass 1998, Elias et al 1999, Fraser et al 1999, Gogou et al 1996, Hawthorne et al 1988, Kavouras et al 2001a, Khalil and Rasmussen 2003, Lau et al 2006, Li and Kamens 1993, Nolte et al 2001, Oros and Simoneit 2001a, b, Rinehart et al 2006, Rogge et al 2006 2003, Schauer et al 1996, Sheesley et al 2003, Simoneit 1989, Simoneit and Elias 2001, Simoneit and Mazurek 1989, Simoneit et al 1990, 1993, b, 2004a, b, Standley and Simoneit 1994, Zheng et al 2002. Source-receptor reconciliation by chemical mass balance (CMB) has been used to characterise the composite sources of organic compounds that includes gasoline vehicle exhaust, meat cooking, cigarette smoke, wood burning, etc.…”

“…The homologous series may range from C 8 to C 38 . The n-alkanals with odd carbon number higher than 20 are of biogenic origin, whereas the lower compounds indicate oxidation of alkanes as possible precursors (Gogou et al 1996). Aldehydes may occur in the epicuticular waxes as a result of the reaction of O 3 on unsaturated hydrocarbons (Garrec 1994).…”

“…Comparatively, few studies have investigated remote, rural and semi-rural environments (Alves et al 2000, Cheng et al 2006, Feng et al 2007, Oliveira et al 2007b, Pio et al 2001a, b, Rissanen et al 2006, Shimmo et al 2004a, Simoneit et al 1990 or have been performed above ocean areas.

In spite of accounting for 10-70% of the atmospheric aerosol mass, particulate-phase organic compounds are not well characterised, and many aspects of aerosol formation and evolution are still unknown. The growing awareness of the impact of particulate aerosols on climate, and the incompletely recognised but serious effects of anthropogenic constituents on air quality and human health, have conducted to several scientific studies. These investigations have provided information about the behaviour of atmospheric particulate matter and the description of the character of its carbonaceous content. The compilation of such results is important as they append to the emergent global-wide dataset of the organic composition of atmospheric aerosols. The contribution of the major emission sources to regional particulate pollution can be diagnosed by using specific molecular markers. This overview is mainly focused on results obtained with gas chromatography coupled with mass spectrometry, since it is the analytical method of choice in elucidating the solvent-extractable organic compounds in atmospheric particulate matter. A synopsis of the selection of organic tracers and the application of geochemical parameters to the analysis of organic constituents as a tool for source apportionment is shown here. Besides the assessment of current knowledge, this paper also presents the identification of further areas of concern.

“…After PM 10 determination, the GFFs/QMFs were divided into two parts using stainless scissors. After that, the Soxhlet extraction of PM 10 filter samples, PM 10 filter blanks, PUF samples and PUF blanks were placed inside the Soxhlets, spiked with a known amount of internal standard (deuterated-PAHs and deuterated-Aliphatics), and extracted with DCM for 24 h. The fractionation/ cleanup process followed the method reported by Gogou et al (1996). After the extraction, the DCM solvent was concentrated to dryness by a combination of rotary evaporation and blowing under a gentle nitrogen stream.…”

It is well known that increased incidences of lung, skin, and bladder cancers are associated with occupational exposure to PAHs. Animal studies show that certain PAHs also can affect the hematopoietic and immune systems and can produce reproductive, neurologic, and developmental effects. As a consequence, several studies have been attempted to investigate the fate of PAHs in atmospheric environment during the past decades. However, there is still a lack of information in regard to the atmospheric concentration of PAHs during the "Bon Fire Night". In this study, twenty-three polycyclic aromatic hydrocarbons and twenty-eight aliphatics were identified and quantified in the PM 10

Nonpolar organic compounds as PM_2.5 source tracers: Investigation of their sources and degradation in the Pearl River Delta, China

et al. 2016

A group of nonpolar organic compounds (NPOCs) in five compound classes including alkanes, polycyclic aromatic hydrocarbons (PAHs), hopanes, steranes, and 1,3,5‐triphenylbenzene were quantified in samples of particulate matter of aerodynamic diameter less than 2.5 μm collected at four sites in the Pearl River Delta (PRD) region, China, over a 2 year period from 2011 to 2012. The four sites include industrial (Nanhai), urban (Guangzhou), urban outskirt (Dongguan), and suburban (Nansha) locations. Some NPOCs are uniquely emitted from particular combustion sources and thereby serving as markers in source apportionment. Based on this multiyear and multisite NPOC data set, spatial and seasonal variations, correlation analysis, and ratio‐ratio plots were used to investigate the source information and degradation of NPOC tracers. In summer, NPOCs showed distinct local emission characteristics, with urban sites having much higher concentrations than suburban sites. In winter, regional transport was an important influence on NPOC levels, driving up concentrations at all sampling sites and diminishing an urban‐suburban spatial gradient. The lighter NPOCs exhibited more prominent seasonal variations. Such spatiotemporal features suggest that their particle‐phase abundance is more influenced by temperature, which is a critical factor in controlling the extent of semivolatile organics partitioned into the aerosol phase. The heavier NPOCs, especially PAHs, showed negligible correlation among the four sites, suggesting more influence from local emissions. Ratio‐ratio plots indicate photodegradation and mixing of various sources for the NPOCs in the PRD. A positive matrix factorization (PMF) analysis of this large NPOC data set suggests that heavier NPOCs are more suitable source indicators than lighter NPOCs. Incorporating particle‐phase light NPOC concentrations in PMF produces a separate factor, which primarily contains those light NPOCs and likely is not a source factor. Total NPOC concentrations predicted using Pankow partitioning theory were explored as PMF inputs; however, the PMF solution is not able to fully explain the input total concentrations or to give reasonable source profiles, suggesting the need for reliable gas‐phase NPOC data before their use in source apportionment studies. In addition, degradation of NPOCs needs to be considered to avoid misinterpretation of PMF source apportionment results.
