Arctic autochthonous communities and the environment face unprecedented challenges due to climate change and anthropogenic activities. One less-explored aspect of these challenges is the release and distribution of anthropogenic nanomaterials in autochthonous communities. This study pioneers a comprehensive investigation into the nature and dispersion of anthropogenic nanomaterials within Arctic Autochthonous communities, originating from their traditional waste-burning practices. Employing advanced nanoanalytical tools, we unraveled the nature and prevalence of nanomaterials, including metal oxides (TiO2, PbO), alloys (SnPb, SbPb, SnAg, SnCu, SnZn), chromated copper arsenate-related nanomaterials (CuCrO2, CuCr2O4), and nanoplastics (polystyrene and polypropylene) in snow and sediment near waste burning sites. This groundbreaking study illuminates the unintended consequences of waste burning in remote Arctic areas, stressing the urgent need for interdisciplinary research, community engagement, and sustainable waste management. These measures are crucial to safeguard the fragile Arctic ecosystem and the health of autochthonous communities.
