“…The island of Yeongdo in Busan is a growing representative area of marine urban tourism that simultaneously encompasses aspects of marine and urban leisure (Park et al, 2019;Zhan et al, 2021). Due to these geographical characteristics and marine industry activities, it was suspected that the coast of Busan city is highly contaminated by MPs (Kwon et al, 2020;Lee and Khim, 2022); however, to the best of the authors' knowledge, no studies have characterized the microbial communities of MPs along the Korean coastal area.…”

This study investigated the potential role of the concentration, shape, size, and polymer type of microplastics (MP), in addition to the microbial community in six coastal areas of Busan city, South Korea. The results showed that the average MP concentration was 94 ± 41 particles·m-3, and particles sized 20 μm –300 μm accounted for 67.5 ± 9.6% of the total MP abundance throughout the study sites. Further, polyethylene (PE), polypropylene (PP), and polystyrene (PS) polymers were abundant among the collected fragment- and fiber-shaped MPs, implying that highly populated and industrialized areas are major sources of MPs contamination. Moreover, the bacterial diversity and taxa-based on 16S rRNA gene sequencing was significantly different between MPs and seawater (SW) samples. Specifically, Psychrobacter, Pseudomonas, Flavobacterium, and Winogradskyella were significantly enriched in MPs compared with SW (p <0.05). Redundancy analysis revealed that nutrient concentrations, salinity, and temperature potentially contributed to shaping the microbial communities on MPs. These results indicate the dynamic and complicated interactions of MP contamination with the physiochemical and environmental factors of the surrounding area. Our findings would help in understanding of MP contamination levels in marine environments and their characteristics, as well as bacterial colonization on plastics in urban coastal areas of Busan, South Korea.
