The OSU SRP – DOSE partnership in 2011 in front of a traditional smoking tipi includes SRP trainees Andres Cardenas and Oleksii Motorykin, and CEC Co-leaders Dr. Barbara Harper and Stuart Harris.

The Department of Science and Engineering (DOSE) of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) is a partner with our Superfund Research Program (SRP) Community Engagement Core (Core E).

In June 2014, DOSE recruited nine Tribal members to help with a study that would measure how people metabolize and eliminate polycyclic aromatic hydrocarbons (PAHs) that can attach to food when it is smoked.

PAHs are produced by burning wood and other materials. Salmon, a first food, is important to the subsistence of Native Americans living in the Pacific Northwest. The salmon run in spring and fall. Smoking salmon is one of the traditional ways to preserve this seasonally abundant food and make it available year round.

The study team first conducted a community educational forum for study volunteers that described the purpose of the study and get informed consent. Each participant was asked to refrain from eating any foods containing PAHs for two days. Then they were asked to eat a small serving of traditionally smoked salmon.  After eating the salmon they provided urine samples to help researchers understand how the PAH residues produced during smoking events are processed by the body.

SRP Trainee Oleksii Motorykin (Project 5) is involved in this study and is working with CORE E and DOSE Scientists to interpret the data.

The Community Engagement Core has a wealth of resources shared on the web site related to working with Tribes. Be sure to check it out!

The OSU Superfund Center’s Community Engagement Core is fortunate to have an established partnership with the Confederated Tribes of the Umatilla Indian Reservation (CTUIR).

The recently produced CTUIR – OSU 2012-2013 Newsletter shares the background, summary, and findings of a collaborative research project to understand polycyclic aromatic hydrocarbon (PAH) exposure related to smoked salmon.

Salmon, a first food, is important to the subsistence of Native Americans living in the Pacific Northwest. Smoking salmon is one of the traditional ways to preserve this seasonally abundant food and make it available year round.

People can be exposed to PAHs from breathing contaminated air or eating smoked foods although many other exposure pathways exist.

Each volunteer wore air sampling equipment and turned it on every time they went into the smoking structures.

The data showed the air in the tipi and the smoke shed contained PAHs.

The findings from this study were published in the Journal of Agricultural & Food Chemistry.

Indigenous cultures perceive the natural environment as an essential link between traditional cultural practices, social connectedness, identity, and health. Many tribal communities face substantial health disparities related to exposure to environmental hazards. We asked 27 volunteers who were members of the CTUIR their opinions on meanings of health and how their environment interacts with their health.

The findings from the focus group discussions were published in the journal Environmental Justice.
