Abstract

Plastic pollution (including microplastics) has been reported in a variety of biotic and abiotic compartments across the circumpolar Arctic. Due to their environmental ubiquity, there is a need to understand not only the fate and transport of physical plastic particles, but also the fate and transport of additive chemicals associated with plastic pollution. Further, there is a fundamental research gap in understanding long-range transport of chemical additives to the Arctic via plastics as well as their behavior under environmentally relevant, Arctic conditions. Here, we comment on the state of the science of plastic as carriers of chemical additives to the Arctic, and highlight research priorities going forward. We suggest further research on the transport pathways of chemical additives via plastics from both distant and local sources and laboratory experiments to investigate chemical behavior of plastic additives under Arctic conditions, including leaching, uptake, and bioaccumulation. Ultimately, chemical additives need to be included in strategic monitoring efforts to fully understand the contaminant burden of plastic pollution in Arctic ecosystems.
塑料作为北极化学添加剂的载体:在环北极进行战略监测的可能性
据报道,环极北极地区的各种生物和非生物区中存在塑料污染(包括微塑料)。由于它们在环境中无处不在,不仅需要了解物理塑料颗粒的命运和运输,还需要了解与塑料污染相关的添加剂化学品的命运和运送。此外,在理解化学添加剂通过塑料向北极的长期运输以及它们在与环境相关的北极条件下的行为方面,还存在根本性的研究空白。在这里,我们评论了塑料作为北极化学添加剂载体的科学现状,并强调了未来的研究重点。我们建议进一步研究来自遥远和当地来源的化学添加剂通过塑料的运输途径,并进行实验室实验,以研究塑料添加剂在北极条件下的化学行为,包括浸出、吸收和生物累积。最终,需要将化学添加剂纳入战略监测工作,以充分了解北极生态系统中塑料污染的污染物负担。

期刊介绍: Arctic Science is an interdisciplinary journal that publishes original peer-reviewed research from all areas of natural science and applied science & engineering related to northern Polar Regions. The focus on basic and applied science includes the traditional knowledge and observations of the indigenous peoples of the region as well as cutting-edge developments in biological, chemical, physical and engineering science in all northern environments. Reports on interdisciplinary research are encouraged. Special issues and sections dealing with important issues in northern polar science are also considered.
