Session Description
Chemical contaminants, such as persistent organic pollutants (POPs) and emerging chemicals of concern, can transport through the atmosphere, rivers and oceans reaching remote locations, including the Arctic, Antarctic and the Third Pole of Hindu Kush-Karakoram-Himalayan (HKKH) mountain region. While many of these contaminants have few local sources in the Arctic and Antarctic, some are detected at levels high enough to risk the health of the environment and humans. The polar environments are experiencing unprecedented changes with extreme sea ice retreat, melting snow and glacier, thawing permafrost and greater frequency of extreme weather events. These changes can lead to new and different sources of contaminants within and outside the Polar Regions, which may impact contaminant distribution and fate, and increase the exposure levels to the ecosystem and humans in these remote regions. In this session, we will explore the current status of contaminants; their transport pathways; reaction, degradation and multimedia partitioning processes; fate, trends and impacts on the polar environment, biota and humans; and how current and predicted changes in climate can affect contaminant distribution, trends and impacts. This session welcomes studies on all aspects of contaminants in the Arctic, Antarctic and Third Pole atmosphere, hydrosphere, cryosphere, terrestrial and freshwater/ marine biota, and humans. All research studies including field and laboratory observations, as well as studies on combined effects of multiple stressors, climate change and modeling studies are welcomed.

Please note that abstract submission before the March 25 deadline is free but a $50 non-refundable fee will be charged to handle submissions from between March 26 and April 1.
