NCP and IPY INCATPA - Atmospheric Organic Contaminants Measurements, Alert, Nunavut, Canada

This project involves the measurement of organic contaminants in Arctic air and is part of a continuing monitoring program started in 1992. The measurement of amounts and types of contaminants involves collecting large volumes of air through filters which are then analyzed in a laboratory. Results are used for chemical risk assessment and risk management under national and international control agreements and to test atmospheric models that explain the movement of contaminants from sources in the South to the Arctic. This information is invaluable due to the long-term monitoring history at this location which can be used as a reference for background levels and contaminant transport history in the Arctic. A newly-developed flow-through air sampler specifically designed for use in cold environments has been deployed at Alert in October 2007 and decommissioned in September 2011.

SVOCs were measured using 3 methods: (1) 7-day integrated high volume air sampling using one glass fiber filter and two polyurethane foam (PUF) plugs analyzed once every 4 weeks giving concentrations of polychlorinated biphenyls (PCBs), organochlorine pesticides, polybrominated diphenyl ethers (PBDEs) and non-BDE flame retardants in picogram per cubic meter (1992-ongoing). (2) 7-day integrated high volume air sampling using one glass fiber filter and a PUF/XAD cartridge analyzed once per month Oct-Feb & once every 2 weeks Mar-Sep giving concentrations of per- and polyfluoroalkyl substances (PFASs) and current-use pesticides in picogram per cubic meter (2006-ongoing). (3) 7-day integrated high volume air sampling using one glass fiber filter analyzed once a month for organophosphate flame retardants (2015 May-ongoing).
