A new science paper combining Sámi knowledge and science documents the very first microplastics in Sámi home area. The Skolt Sámi teams worked with the researchers for four years to document, assess and quantify the situation – microplastics are even in the most remote parts of Sámi area. Accompanying documentary film explains the process.
We explored the presence of microplastics in the Finnish Arctic Sámi home area. A dialogue between Indigenous knowledge and scientific field work produced data about microplastics in remote wilderness aquatic ecosystems.
Methods included geographical Indigenous knowledge analysis, water sampling with fraction filtration, and imaging Fourier transform infrared spectroscopy. The MPs found were small; the mean particle size was 126 ± 121 μm. Particle concentrations of MPs in freshwater and marine samples varied between 45 and 423 MPs m−3 and the most common polymer types were polyethylene, polypropylene, and polyethylene terephthalate.
In conclusion, because microplastics are present even in the wilderness areas, their abundance should be monitored to assess plastic pollution in the relatively pristine Arctic environments. Sámi Indigenous knowledge proved to be a beneficial and important initiator, because locals recognize the possible sources and transport pathways of plastic litter, and practical sampling sites in the complex freshwater systems of the area.
