AbstractOPP-99-79695OPP-99-79689This is a collaborative proposal with Oregon State University and Ithaca College. The Principal Investigators will study two potential sources of contaminants that are arctic freshwater environments - atmospheric deposition and biological vectors, specifically, anadromous fish that carry contaminants from marine to freshwater environments. They will investigate the relative importance of these two routes of contaminant delivery for freshwater systems of western Alaska using landlocked lakes and lakes with a fluvial connection to the sea.Both the anadromous least cisco (Coregonus sardinella) and the freshwater Arctic grayling (Thymallus arcticus) are important subsistence species in the western Arctic. In sub-arctic regions, graylings have been found to have higher contaminant concentrations and a different fingerprint of organochlorines (OCs) contaminants in lakes where they co-exist with sockeye salmon (Onchorhynchus nerka). The Principal Investigators will attempt to determine whether the same situation pertains in the Arctic where OCs are believed to be derived primarily from atmospheric sources.Study locations will be chosen in partnership with the North Slope Borough Wildlife Department and local communities. Several small interview sessions will be arranged to enable the Principal Investigators and the Traditional Ecological Knowledge (local residents) opportunities to share information and communicative results.

摘要OPP-99-79695OPP-99-79689这是与俄勒冈州立大学和伊萨卡学院的合作提案。 首席研究员将研究北极淡水环境中的两个潜在污染物来源——大气沉积和生物载体，特别是将污染物从海洋环境带到淡水环境的溯河产卵鱼类。 他们将利用内陆湖泊和与海洋相连的河流调查阿拉斯加西部淡水系统的这两种污染物输送途径的相对重要性。溯河产卵的小西斯科鱼（Coregonus sardinella）和淡水北极河鳟（Thymallus arcticus）都是北极西部地区重要的生存物种。 在亚北极地区，河鳟与红鲑 (Onchorhynchus nerka) 共存的湖泊中被发现具有较高的污染物浓度和不同的有机氯 (OC) 污染物指纹。 主要研究人员将尝试确定北极地区是否存在同样的情况，据信北极地区的有机碳主要来自大气源。研究地点将与北坡自治市野生动物部门和当地社区合作选择。 将安排几次小型访谈，让首席研究员和传统生态知识（当地居民）有机会分享信息和交流结果。
