| Abstract | A wide variety of sampling techniques and strategies are needed to analyze polycyclic aromatic compounds (PACs) and interpret their distributions in various environmental media (i.e., air, water, snow,
soils, sediments, peat and biological material). In this review, we provide a summary of commonly employed sampling methods and strategies, as well as a discussion of routine and innovative approaches used to quantify and characterize PACs in
frequently targeted environmental samples, with specific examples and applications in Canadian investigations. The pros and cons of different analytical techniques, including gas chromatography - flame ionization detection (GC-FID), GC low-resolution
mass spectrometry (GC-LRMS), high performance liquid chromatography (HPLC) with ultraviolet, fluorescence or MS detection, GC high-resolution MS (GC-HRMS) and compound-specific stable (?13C, ?2H) and radiocarbon (?14C) isotope analysis are
considered. Using as an example research carried out in Canada's Athabasca oil sands region (AOSR), where alkylated polycyclic aromatic hydrocarbons and sulfur-containing dibenzothiophenes are frequently targeted, the need to move beyond the standard
list of sixteen EPA priority PAHs and for adoption of an AOSR bitumen PAC reference standard are highlighted. A comprehensive review of sampling methods, strategies and analytical techniques used to quantify and characterize PACs in the Canadian
environment. |
| Summary | (Plain Language Summary, not published)
This review is part of a series of articles to be submitted the journal Environmental Pollution on the 'State of Knowledge Report on Polycyclic aromatic
compounds (PACs) in the Canadian Environment'. In this paper, we provide a review of commonly employed sampling methods and instrumentation, as well as innovative approaches used to quantify and characterize PACs in frequently targeted environmental
samples. While the discussion presented here is applicable to other regions, here we focus on examples and issues specific to Canadian investigations. The author list is comprised of experts who work in this field. |
