| 北极圈内的持久性有机污染物和新兴关注化合物 Levels and Fate of Persistent Organic Pollutants and Chemicals of Emerging Concern in the Arctic | |||
| 分会内容： | Environmental pollutants, such as persistent organic pollutants (POPs), reach the Arctic primarily through long-range transport (LRT) via atmospheric and oceanic/river currents. Conversely, emerging Arctic contaminants (CEACs) often originate from local sources like industrial, municipal, or infrastructure-related releases. Despite their different origins, these contaminants exert detrimental effects on both the environment and indigenous populations. Moreover, the Arctic is undergoing unprecedented climate changes, including the loss of marine and terrestrial cryosphere. This, coupled with the introduction of new anthropogenic contaminants applied or released to facilitate Arctic resource exploitation, is significantly disrupting Arctic ecosystems. This session aims to comprehensively assess the status of contaminants in the region, encompassing external entry through LRT and local release into the Arctic environment. We will explore various facets of these pollutants, including their sources, potential for long-range transport, environmental fate, spatial and temporal trends, multimedia partitioning processes, and, crucially, their impacts on polar ecosystems and human health amid the changing Arctic dynamics. The implications of ongoing research, regulatory measures, and assessment strategies for CEACs will be also delved. Researchers in different expertise will be invited to present their scientific findings. This session will highlight scientific, chemical, and toxicological perspectives contributing to sustainable pollution mitigation in the Arctic. | ||
