由于气候变化和人为活动,北极自生社区和环境面临前所未有的挑战。这些挑战的一个较少探索的方面是人为纳米材料在本土社区的释放和分布。这项研究开创了对北极原住民社区中人为纳米材料的性质和分散的全面调查,源于他们传统的废物燃烧做法。采用先进的纳米分析工具,我们揭示了纳米材料的性质和普遍性,包括金属氧化物(TiO2,PbO),合金(SnPb,SbPb,SnAg,SnCu,SnZn),铬化砷酸铜相关纳米材料(CuCrO2,CuCr2O4),以及废物燃烧地点附近的雪和沉积物中的纳米塑料(聚苯乙烯和聚丙烯)。这项开创性的研究阐明了偏远北极地区废物燃烧的意外后果,强调跨学科研究的迫切需要,社区参与,可持续的废物管理。这些措施对于保护脆弱的北极生态系统和当地社区的健康至关重要。
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.
