Spatial and seasonal distribution of microplastics in various environmental compartments around Sishili Bay of North Yellow Sea, China
AI summary Read the abstract
Researchers mapped the spatial and seasonal distribution of microplastics across multiple environmental compartments around Sishili Bay, China, finding distinct variation patterns in abundance and particle shapes between beach, river, water column, and sediment samples.
Microplastic pollution in the marine environment is closely linked to human activities, particularly in coastal areas. Seasonal samples were collected on the beach, in rivers, surface water, bottom water, and subtidal sediments from May 2019 to February 2020. Microplastics in environment metrices showed different seasonal variation characteristics of both abundance and shapes, and their spatial distribution varied in different environment metrices. The most common shapes of microplastic in water and sediment were fibers and fragments. Foams were evident on the beach sand with seasonal distribution. Results from this study show that microplastics in coastal areas are vulnerable to human activities, such as marine aquaculture and fishery activity. The variation in vertical profiles indicated the presence of a complicated mechanism in water column. The typical microplastics inventory suggested sediment as the main sink in coastal area. More investigations are needed to understand the distribution of microplastic in the coastal region.

AI summary Read the abstract
Seasonal variation in the concentrations and characteristics of micro- and meso-plastics in the surface seawater of Jiaozhou Bay, China, was quantified across four seasons. Concentrations peaked in spring and were lowest in winter, suggesting seasonal inputs from runoff and human activity drive plastic abundance in this semi-enclosed coastal bay.
