渥太华资源管理局(CORA)的部落间渔业和评估计划(ITFAP)。自1991年以来，密歇根州的玛丽一直在监测苏必利尔湖、休伦湖和密歇根湖水域的湖鲑鱼(Salvelinus Namaycush)和湖白鱼(Coregonus Clupeaformis)鱼片部分的污染物浓度。这篇文章的主要目的是提出根据营养效益进行调整的甲基汞(MeHg)的风险量化，最初由Ginsberg和Toal(2009,2015)提出，我们最近在Dellinger Etal上报道了这些商业鱼类鱼片部分的污染物浓度趋势。(2014)。部落渔民捕获的这两种鱼如果以每周6盎司的速度食用，对心血管健康和婴儿神经发育都有明显的好处。然而，其他普遍食用的鱼类，如鳕鱼、金枪鱼和罗非鱼，估计对心血管健康和婴儿神经发育只有轻微的好处或净负面影响。这种对收益和风险的动态评估进一步表明了传统捕捞的鱼对部落健康的重要性。
The Inter-Tribal Fisheries and Assessment Program (ITFAP) of the Chippewa Ottawa Resource Authority (CORA) in Sault Ste. Marie, Michigan, has been monitoring contaminant concentrations in the fillet portions of lake trout (Salvelinus namaycush) and lake whitefish (Coregonus clupeaformis) from the waters of lakes Superior, Huron, and Michigan since 1991. The primary purpose of this article is to present a risk quantification of methylmercury (MeHg) that is adjusted for nutritional benefit, originally presented by Ginsberg and Toal (2009, 2015) on trends in contaminant concentrations in fillet portions of these commercial fish that we recently reported in Dellinger etal. (2014). Both species of fish caught by tribal fishermen showed clear benefits to cardiovascular health and infant neurodevelopment if consumed at a rate of six ounces per week. However, other popularly consumed fish such as cod, tuna, and tilapia are estimated to have only marginal benefit or net negative effects on cardiovascular health and infant neurodevelopment. This dynamic assessment of benefits and risks further demonstrates the importance of traditionally caught fish in tribal health.
