The Sitka Tribe of Alaska (STA) has been awarded a one-year, $30,000 grant from the Environmental Protection Agency‘s Environmental Justice Small Grant Program. The grant project, “Microplastics in Tribal Subsistence Foods In Southeast Alaska,” will include the University of Alaska, Mount Edgecumbe High School, the Southeast Alaska Watershed Coalition (SAWC), and Sitka Conservation Society as partners.

“STA will collect water and subsistence food samples from four locations within STA’s traditional territory to test for the presence of microplastics and associated toxins,” Sitka Tribe of Alaska grant administrator Rachel Henderson wrote in an email. “These results will be compared to commercially purchased foods and safety standards. These results will be shared with the public so they can make informed decisions about harvesting traditional foods. Local students will assist with the sampling of local food and water.”
Henderson said Jennifer Hamblen is the project manager for the tribe, and she is working with Jeff Feldspaugh of the tribe’s resource protection department and the tribe’s partner agencies.
“Part of STA’s mission is to help ensure that subsistence resources for STA Tribal Citizens are available and safe,” Hamblen said. “In recent years, there have been many studies and publications from other places, such as British Columbia, about microplastics and their associated toxins having devastating consequences on animals, and potentially affecting the people who consume them. This is a pilot project to see if there are microplastics in subsistence foods in our area and comparing locally collected seafood to seafood available at supermarkets.”

University of Alaska Southeast was written in as a project partner and the UAS conference in July is one of the places that STA will present the results, Henderson said. The Southeast Alaska Watershed Coalition (SAWC) has done microplastic water collection on behalf of salmon in the past, and Sitka Conservation Society (SCS) is very invested and knowledgeable about microplastics and their effects on the environment.
“We’ll be collecting shellfish from the Starrigavan estuary to process for microplastic consumption. We will also collect water samples using the methods already established by SAWC,” Henderson said.
While the project is just starting to launch, it has had one setback, Henderson said. “When we wrote the grant, we were going to send the samples to a certified, plastic-free laboratory, such as the University of Alaska Anchorage’s Applied Science, Engineering, and Technology Laboratory. That lab ran out of funding and is no longer operational, so we’re looking for another lab. Right now Jenn’s writing the QAPP (an EPA requirement before an sample collection that has to be approved before we can start work) so we can collect samples and we’ll look at presence/absence of microplastics with students from Mount Edgecumbe High School. We’ll save samples in case we get an opportunity for a larger project and find an appropriate lab to run phthalate samples. There will be photos with MEHS collecting samples and processing samples after the QAPP is approved.”
