Polycyclic aromatic compounds (PACs) in the Canadian environment: A review of sampling techniques, strategies and instrumentation

What is necessary for next‐generation atmospheric environmental standards? Recent research trends for PM2.5‐bound polycyclic aromatic hydrocarbons and their derivatives

“…As analytical methods for PAHs and their derivatives in air samples have been summarized in several reports (Abbas et al, 2018; Ahad et al, 2020; Bandowe & Meusel, 2017; Hayakawa, Tang, & Toriba, 2017), we present only an overview of advances in the past several years. Analytical techniques that have been used to identify and quantify PAHs and their derivatives include GC with low‐resolution mass spectrometry (GC‐LRMS), GC–MS/MS or high‐resolution mass spectrometry (GC–HRMS), HPLC with fluorescence (FL), chemiluminescence (CL), or MS (MS/MS) detection.…”

“…HPLC with FL detection is also frequently used to quantify PAHs. Both have advantages and disadvantages (Ahad et al, 2020). To detect NPAHs in GC–MS methods, negative ion chemical ionization mode is usually applied because it is more sensitive than EI) mode (Abbas et al, 2018; Bandowe & Meusel, 2017; Hayakawa et al, 2017).…”

Fast Location and Isolation of Phenanthrene-degrading Halophilic Microbial Community and its Degradation Pathway

“…Among all kinds of petroleum compounds, polycyclic aromatic hydrocarbons (PAHs) composed from two or more fused aromatic rings had chemical stability and extremely di cult biodegradation 1 . As an common toxic carcinogenic pollutant to human and animals 2,3 , PAHs threatened human food safety through the accumulation in the food chain 4 . There were large number of PAHs utilizing microbes in high salinity oil polluted sea area and offshore oil eld environment 5,6 .…”

Direct, Isomer-Specific Quantitation of Polycyclic Aromatic Hydrocarbons in Soils Using Membrane Introduction Mass Spectrometry and Chemical Ionization

“…For PAHs in soils, gas chromatography−mass spectrometry (GC−MS) with initial sample extraction, cleanup, and concentration steps is frequently used. 3 While effective, GC−MS and the accompanying sample preparation methods may be disadvantageous with respect to cost and time. Direct mass spectrometry (DMS) methods, which involve the elimination of sample cleanup, preparation, and chromatographic steps, may therefore be advantageous in place of or in combination with conventional (i.e., GC−MS) techniques because of their rapid and simple workflow, ease of use, "real-time" measurement capabilities, reduced consumable needs, and lower costs.…”

“…Polycyclic aromatic hydrocarbons (PAHs), a class of ubiquitous environmental contaminants, are carcinogenic, mutagenic, and bioaccumulative. , PAHs are therefore regulated and routinely tested for in a variety of sample matrices. For PAHs in soils, gas chromatography–mass spectrometry (GC–MS) with initial sample extraction, cleanup, and concentration steps is frequently used . While effective, GC–MS and the accompanying sample preparation methods may be disadvantageous with respect to cost and time.…”
