As an emerging marine environmental issue, marine plastic debris pollution has attracted worldwide attention. Studies have covered more and more areas of the world's oceans. To further understand the sources and variation of marine plastic debris in the surface water of the Bohai Sea, in this study, plastic debris was collected during the four seasons of 2016-2017. The results showed the mean density of plastic debris over these seasons was 0.49 ± 0.18 particles/m. Macro-, meso-, and micro- plastics accounted for 5%, 26%, and 69% of the total number of plastic debris, respectively. The density of the microplastics was 0.35 ± 0.13 particles/m. The highest density was found in spring, followed by summer and winter, and the lowest in autumn. High distribution densities were observed in the Liaodong Bay and the Bohai Strait, which were attributed to the dynamics of the rim current, terrain, and fishery activities. CAPSULE ABSTRACT: Riverine input, dynamics of the rim current, terrain, and fishery activities contribute to the variations in marine plastic debris in the surface water of the Bohai Sea.
作为一个新兴的海洋环境问题，海洋塑料碎片污染引起了全世界的关注。研究已经涵盖了世界海洋越来越多的区域。为了进一步了解渤海表层水中海洋塑料碎片的来源和变化，本研究于 2016 年至 2017 年的四季采集了塑料碎片。结果表明，这些季节的塑料碎片平均密度为 0.49±0.18 个/米。大、中、小塑料碎片分别占塑料碎片总数的 5%、26%和 69%。微塑料的密度为 0.35±0.13 个/米。春季密度最高，其次是夏季和冬季，秋季最低。辽东湾和渤海海峡的分布密度较高，这归因于边缘流的动力学、地形和渔业活动。
