PROJECT SUMMARY (Community Engagement Core: Hoover, Chief, Carroll, Lim) The University of Arizona (UA) Superfund Research Center (SRP) has successfully translated research findings focused on the health and environmental impacts of mining on communities and engaged affected citizens to reduce and mitigate exposure through learning modules, outreach activities, workshops, capacity building, and developing community engaged participatory research. The objective of the UA SRC Community Engagement Core (CEC) is to foster impactful collaborations between Center investigators and community partners in identifying and mitigating human exposures to dust (including metals and mold) from mine waste and material. Recognizing that reducing chronic metal(loid) exposure remains a priority, congruent with NIEHS SRP’s fourth mandate, we will establish and maintain space for multi-directional communication to 1) Implement community engagement training activities that prepares UA SRC members to engage communities in multi-directional dialogue; 2) Develop educational and informational materials that support efforts by Indigenous Peoples to reduce environmental exposures in their communities; and 3) Enhance community based capacity to reduce dust exposure via co-created data collection and monitoring activities. Accomplishing these activities will be achieved through existing, long-term collaborations with The Tohono O’odham Nation, The Navajo Nation, Diné College, San Carlos Apache College, and Black Mesa United community organization. CEC activities will emphasize co-development of educational and information materials to build community capacity to address and reduce environmental dust exposures. In collaboration with the Research Experience and Training Coordination Core (RETCC), the CEC will 1) develop educational and informational materials to support community decision-making about issues including particulate matter, mold, and lung disease with support from
