Abstract:

The long-term time trends of atmospheric pollutants at eight Arctic monitoring stations are reported. The work was conducted under the Arctic Monitoring and Assessment Programme (AMAP) of the Arctic Council. The monitoring stations were: Alert, Canada; Zeppelin, Svalbard; Stórhöfði, Iceland; Pallas, Finland; Andøya, Norway; Villum Research Station, Greenland; Tiksi and Amderma, Russia. Persistent organic pollutants (POPs) such as α- and γ-hexachlorocyclohexane (HCH), polychlorinated biphenyls (PCBs), α-endosulfan, chlordane, dichlorodiphenyltrichloroethane (DDT) and polybrominated diphenyl ethers (PBDEs) showed declining trends in air at all stations. However, hexachlorobenzene (HCB), one of the initial twelve POPs listed in the Stockholm Convention in 2004, showed either increasing or non-changing trends at the stations. Many POPs demonstrated seasonality but the patterns were not consistent among the chemicals and stations. Some chemicals showed winter minimum and summer maximum concentrations at one station but not another, and vice versa. The ratios of chlordane isomers and DDT species showed that they were aged residues. Time trends of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) were showing decreasing concentrations at Alert, Zeppelin and Andøya. The Chemicals of Emerging Arctic Concern (CEAC) were either showing stable or increasing trends. These include methoxychlor, perfluorohexane sulfonic acid (PFHxS), 6:2 fluorotelomer alcohol, and C9-C11 perfluorocarboxylic acids (PFCAs). We have demonstrated the importance of monitoring CEAC before they are being regulated because model calculations to predict their transport mechanisms and fate cannot be made due to the lack of emission inventories. We should maintain long-term monitoring programmes with consistent data quality in order to evaluate the effectiveness of chemical control efforts taken by countries worldwide.

Funding text 1 We would like to acknowledge all site and laboratory operators and students at all AMAP stations. Wong is grateful to Desmond Ng and Jared Chisamore of Environment and Climate Change Canada for help in data analysis. Financial support for the monitoring programmes was provided by the Northern Contaminants Program, Crown-Indigenous Relations and Northern Affairs Canada (Alert); Swedish-EPA (Naturv?rdsverket) and the Finnish Meteorological Institute (Pallas); the Icelandic Ministry for the Environment (St?rh?f?i); the Norwegian Environment Agency (Zeppelin and And?ya); and the Danish Environmental Protection Agency (Villum Research Station). RPA ?Typhoon?, Roshydromet provided support for air monitoring at sites in Russia (Amderma and Tiksi). The Government of Canada's Chemicals Management Plan (CMP) provided partial funding for the analysis of emerging contaminants at Alert.
