Core E: Community Engagement Core (Harding)

项目总结（见说明）： 社区参与核心：社区参与核心将促进俄勒冈州立大学研究人员和美国土著部落在太平洋西北地区的合作，以解决部落对暴露于化学品在其环境中的关注，重点是了解暴露途径多环芳烃（PAH）。我们的社区合作伙伴是乌马蒂拉印第安人保留地联盟部落（CTUIR），Swinomish印第安部落社区和Samish印第安民族。部落社区从不同来源接触多环芳烃和CERCLA优先清单上的许多化学品：他们居住在受危险废物场地影响的保留地，他们从受污染的水道中收集维生食物，他们从受污染的土地上收集传统食物。住房特点和熏制食物等传统做法也是造成他们接触化学品的原因。这些独特途径的累积暴露可能会增加与环境有关的疾病的风险。至关重要的是，部落社区要了解这些风险，并制定文化上适当的应对措施和减少风险的战略，因为他们不能为了避免污染物而离开家园，也不能放弃自己的文化或宗教。反过来，研究界必须根据基于社区的研究原则，发展与部落社区合作的文化能力。社区参与核心的具体目标是：1）解决CTUIR对环境暴露的关注，建立部落测量环境污染物的能力，并制定减少风险的战略，以改善健康，而不会对文化习俗产生不利影响;（二）在CTUIR使用的分析方法中建立部落能力，并帮助Swinomish部落印第安社区和Samish印第安民族提高他们的了解PAH和其他化学品暴露; 3）与其他SRP中心，EPA区域办事处，有毒物质和疾病机构，部落事务办公室和其他利益相关者合作，向居住在受污染土地上的部落人口传播我们的研究结果和基于社区的环境健康研究原则。

PROJECT SUMMARY (See instructions): Community Engagement Core: Tribal-University Evaluation of Chemical Exposures to Improve Community Health The Community Engagement Core will facilitate collaborations among OSU researchers and Native American Tribes in the Pacific Northwest to address Tribal concerns regarding exposure to chemicals in their environment, with a focus on understanding exposure pathways to polycyclic aromatic hydrocarbons (PAHs). Our community partners are the Confederated Tribes of the Umatilla Indian Reservation (CTUIR), the Swinomish Indian Tribal Community, and the Samish Indian Nation. Tribal communities experience exposure to PAHs and many chemicals on the CERCLA priority list from diverse sources: they reside on reservations impacted by hazardous waste sites, they collect subsistence foods from contaminated waterways, and they gather traditional foods from contaminated lands. Housing characteristics and traditional practices such as smoking foods also contribute to their chemical exposures. The cumulative exposures from these unique pathways may increase the risk of environmentally-related disease. It is critically important that Tribal communities understand these exposures and develop culturally appropriate responses and risk reduction strategies because they cannot move from their homelands to avoid contaminants and they cannot give up their culture or their religion. In turn, the research community must develop the cultural capacity to work with Tribal communities according to the principles of community-based research. The specific aims of the Community Engagement Core are to: 1) address CTUIR concerns regarding their environmental exposures, build Tribal capacity to measure environmental pollutants, and develop risk reduction strategies that will improve health without adversely affecting cultural practices; 2) build tribal capacity in analytical methods used by the CTUIR and help both the Swinomish Tribal Indian Community and the Samish Indian Nation to improve their understanding of PAH and other chemical exposures; 3) collaborate with other SRP Centers, EPA regional offices, the Agency for Toxic Substances and Disease, the Office of Tribal Affairs, and other stakeholders to disseminate our research findings and the principles of community-based environmental health research with tribal populations that reside on contaminated lands.
