Polychlorinated biphenyls (PCBs) can be used as chemical sentinels for the assessment of anthropogenic influences on Arctic environmental change. We present an overview of studies on PCBs in the Arctic and combine these with the findings from ArcRisk—a major European Union-funded project aimed at examining the effects of climate change on the transport of contaminants to and their behaviour of in the Arctic—to provide a case study on the behaviour and impact of PCBs over time in the Arctic. PCBs in the Arctic have shown declining trends in the environment over the last few decades. Atmospheric long-range transport from secondary and primary sources is the major input of PCBs to the Arctic region. Modelling of the atmospheric PCB composition and behaviour showed some increases in environmental concentrations in a warmer Arctic, but the general decline in PCB levels is still the most prominent feature. ‘Within-Arctic’ processing of PCBs will be affected by climate change-related processes such as changing wet deposition. These in turn will influence biological exposure and uptake of PCBs. The pan-Arctic rivers draining large Arctic/sub-Arctic catchments provide a significant source of PCBs to the Arctic Ocean, although changes in hydrology/sediment transport combined with a changing marine environment remain areas of uncertainty with regard to PCB fate. Indirect effects of climate change on human exposure, such as a changing diet will influence and possibly reduce PCB exposure for indigenous peoples. Body burdens of PCBs have declined since the 1980s and are predicted to decline further.

Arctic Health Risks: Impacts on health in the Arctic and Europe owing to climate-induced changes in contaminant cycling (ArcRisk) was funded by the Seventh European Research Framework Programme (FP-7) (Grant agreement 226534). The Arctic Monitoring and Assessment Programme (AMAP) provided the professional network and the Coordinator for the ArcRisk project.
The Nordic Council of Ministers (NCM) as well as the Research Council of Norway (RCN) provided funding for several supporting studies reported here. The significant in-kind contributions of all institutions (see author list) involved in ArcRisk and other projects reported here are greatly appreciated.
