Short summary

A new clean-up method for the SUS and NTS of organic contaminants was applied to high-volume Arctic air samples. A large number of known and new potential organic chemicals of emerging Arctic concern were identified and prioritised with GC×GC-LRMS; 60 % of the identified contaminants (not yet detected in Arctic samples) do not meet currently accepted criteria for LRATP into polar environments. Without our empirical confirmation, they would not be considered potential Arctic contaminants.
