Analytical Methods for the Determination of Emerging Organic Contaminants in the Atmosphere

Emerging organic contaminants (EOCs) include several groups of organic compounds that have been wildly distributed in the environment and attracted tremendous attention over the past decades. Analyses of EOCs in water have been reviewed in several special issues of Analytical Chemistry (Richardson and Ternes 2005; Richardson 2007). These important articles highlighted the current issues in the developments of instrumental technologies related to the detection of EOCs. In another important issue, Environmental Science and Technology published an excellent perspective in “what is emerging?” (Muir et al. 2006). This article pointed out that the longevity of a contaminant’s emerging status is typically determined by whether the contaminants are persistent or have potentially harmful human or ecological effects. The EOCs discussed in this paper are selected on the basis of the reviews made for emerging contaminants in water analysis (Richardson and Ternes 2005; Richardson 2007) and review for potential candidates of persistent organic pollutants (Muir et al. 2006). The EOCs include polyfluorinated alkyl substances (PFASs), (perfluorooctanoic acid (PFOA), perfluorooctanesulfonate (PFOS) and others), brominated flame retardants (BFRs) and their degradation products, polybrominated dibenzo-p-dioxins (PBDDs), and polybrominated dibenzofurans (PBDFs), synthetic musk fragrances, organophosphate esters, alkylphenols (APs) and bisphenol A (BPA). The acronyms of individual compounds are listed in Table 20.1.
