Abstract
Numerous chemicals have been manufactured from industrial activities and used as consumer products since the late 18th century. Non-target analysis is a new analytical tool to detect many chemicals in environmental samples and to prioritize emerging contaminants. In this study, the suspect and non-target analytical methods were optimized using a gas chromatography coupled to time-of-flight (GC/TOF) to propose contaminants of emerging concerns for the Arctic environment. Suspect analytical method was developed with qualification and qualifier ions, isotopic ratio, and retention time of 215 contaminants including persistent organic pollutants (POPs) to establish in-house library. Nontarget analytical method was also optimized with deconvoluted ion chromatogram, which is a possible form to match the mass spectrum of the NIST library. Multiple environmental samples such as seawater, air, soil, sediment, sludge, and sea ice collected from the Arctic region were analyzed with suspect and non-target analysis of GC/TOF after the cleanup procedure of solid phase extraction (SPE) cartridge. The commonly detected contaminants in the Arctic environmental samples were siloxanes, organophosphate flame retardants, phthalates, synthetic musk compounds, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons. Among them, siloxanes and OPFRs were proposed as contaminants of emerging concerns for the Arctic environment. This is the first report to prioritize emerging contaminants in the Arctic environment with suspect and non-target analysis of GC/TOF.
