齐佩瓦渥太华资源管理局监测Anishinaabe（大湖美洲土著人）部落渔业的鱼类污染物。本文更新了先前报告的两种持久性生物累积性有毒物质（PBT）的趋势，这两种物质是这些鱼类消费咨询限值的主要贡献者：甲基汞（MeHg）和多氯联苯（PCB）。此外，我们首次报告了这些相同的上五大湖鱼类收获的营养效益生物指标和指标的分析：硒（Se）和欧米茄-3脂肪酸（PUFA-3s）。本文报告了一种新的风险/效益量化方法，该方法最初由Ginsberg等人提出，旨在描述脂肪酸益处与有毒甲基汞健康结果之间的权衡。我们还报告了一个硒效益指标，以表征可能的保护价值对甲基汞神经毒性的基础上Ralston等人。符合Anishinaabe文化的动机，消费鱼类从他们的祖先渔业，营养含量高，在当地捕获的鱼，在某些方面，上级养殖/商店买的鱼。这些五大湖的鱼仍然含有一定水平的PBT，需要对消费者进行仔细的教育和指导。然而，污染的趋势表明，这些鱼不需要被遗弃作为重要的（文化和营养）食物来源的Anishinaabe谁收获他们。
The Chippewa Ottawa Resource Authority monitors fish contaminants in Anishinaabe (Great Lake Native American) tribal fisheries. This paper updates previously reported trends in two Persistent Bioaccumulative Toxic (PBT) substances which are the primary contributors to consumption advisory limits for these fish: Methylmercury (MeHg) and Polychlorinated Biphenyls (PCBs). Also, we report for the first time, an analysis of nutritional benefit bioindicators and metrics in these same Upper-Great Lakes fish harvests: Selenium (Se) and Omega-3 Fatty Acids (PUFA-3s). A novel risk/benefit quantification originally presented by Ginsberg et al is reported here to characterize the tradeoffs between fatty acid benefits and toxic MeHg health outcomes. We also report a Se benefit metric to characterize the possible protective value against MeHg neurotoxicity based on Ralston et al. Congruent with Anishinaabe cultural motivations to consume fish from their ancestral fisheries, nutritional content was high in locally-caught fish and, in some respects, superior to farmed/store-bought fish. These Great Lakes fish still contained levels of PBTs that require careful education and guidance for consumers. However, the contaminant trends suggest that these fish need not be abandoned as important (both culturally and nutritionally) food sources for the Anishinaabe who harvested them.
