Microplastic contamination and microbial colonization in coastal area of Busan City, Korea

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...

description 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.
