AB  - Numerous chemicals have been manufactured through 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, suspect and non-target 
      analytical methods were optimized using gas chromatography coupled with 
      time-of-flight (GC/TOF) to propose contaminants of emerging concern for the 
      Arctic environment. A suspect analytical method was developed with qualification 
      and qualifier ions, isotopic ratios, and retention times of 215 contaminants 
      including persistent organic pollutants (POPs) to establish an in-house library. 
      Non-target analytical method was also optimized with a deconvoluted ion 
      chromatogram, which is a form that can possibly match the mass spectrum of the 
      NIST library. Multiple environmental samples, such as seawater, air, soil, 
      sediment, sludge, and iceberg, collected from the Arctic region were analyzed 
      with suspect and non-target analysis of GC/TOF after the clean-up procedure with 
      a 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 organophosphate flame 
      retardants were proposed to be 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.
