Microplastics (MPs) in the Arctic Ocean have gained considerable attention due to its ubiquity and impacts within ecosystems. However, little information is available on MPs in the Pacific section of the Arctic Ocean. The present study determined the abundance, distribution, and composition of MPs in surface waters from the Northwestern Pacific, the Bering Sea, and the Chukchi Sea. The MPs abundances varied from 0.018 items/m to 0.31 items/m, with a mean abundance of 0.13 ± 0.11 items/m. The highest level of MPs was found in the Chukchi Sea. Of all of the detected MPs, polyethylene terephthalate (PET) accounted for the largest proportion of MPs, and fiber was predominant with regard to the total amount. Our results highlighted that the Arctic Ocean is becoming a hotspot for plastic pollution, and the risks posed by MPs need to be paid closer attention in future investigations.
北极海洋中的微塑料（MPs）因其在生态系统中的普遍性和影响而受到广泛关注。然而，有关北极海洋太平洋部分的 MPs 的信息却很少。本研究确定了西北太平洋、白令海和楚科奇海表层水中 MPs 的丰度、分布和组成。 MPs 的丰度范围为 0.018 项/米至 0.31 项/米，平均值为 0.13±0.11 项/米。 MPs 的最高水平出现在楚科奇海。在所有检测到的 MPs 中，聚对苯二甲酸乙二醇酯（PET）占 MPs 的比例最大，而纤维在总量方面占主导地位。我们的研究结果表明，北极海洋正在成为塑料污染的热点，未来的研究需要更加关注 MPs 所带来的风险。
