Unpublished data

The objectives of this project are: 1) to collect a set of baseline air concentration data for new and emerging chemicals in the Arctic against which future trends, sources and sinks may be evaluated, focusing on new Flame Retardants and polycyclic aromatic compounds (PACs); 2) to assess the feasibility of collecting air samples for PACs from a diesel burning ship, to assess the PACs combustion signature of that ship and to make a first estimate of the impact of increased marine traffic on the archipelago air quality; 3) continue time trends of POPs in air and water as a mechanism for assessing the impact of regulatory decisions and climate change on Arctic contamination; and 4) to apply the ocean contaminant data to the design of a practical monitoring strategy for Canadian Arctic waters including assessing the feasibility of passive water sampling.

Summary: The Arctic is increasingly being impacted by legacy and emerging persistent organic pollutants (POPs) through increased shipping traffic in the North-West Passage, transport from the growing oil and gas industry and through continuous air and oceanic transport. These compounds include flame retardants (FRs), polycyclic aromatic compounds (PACs), perfluoroalkyl compounds (PFACs) and legacy organochlorine and current use pesticides (OCPs and CUPs). The likely sources of PACs including polycyclic aromatic hydrocarbons (PAHs) and methylated-PAHs (Me-PAH) in the Arctic are a combination of local burning for electricity (Iqaluit's sole source of electricity is from diesel fuel), emissions from diesel burning ships, local oil exploration, forest fires and long range transport from more southern emission regions. As other POPs decline, PAHs may become the dominant POP in the Arctic environment.

Flame retardants (FR), both brominated (BFRs) and organophosphate (OP FRs), are receiving increased attention due to their presence, and in the case of OP FRs, higher than expected levels in the arctic atmosphere. The widespread global distribution of BFRs and OP FRs is believed to occur through oceanic transport and air transport in the gas-phase and sorbed to particles. As some BFRs are banned and added to international regulations, the use of alternative FR will increase, including OP FRs and novel-BFRs. Research Program(s): ArcticNet,NCP.
