The research revealed low abundance of microplastics in the Jiangsu Coastal Area, with a distribution trend of high near shore and low far shore, and the most severe pollution in the southernmost part. Clothing fibers were identified as the main source in the northernmost and southernmost regions, while decomposition of hard, large plastic waste was the major source type in the middle region.
We investigated the pollution characteristics, the spatial distributions of microplastics, and the source compositions in the Jiangsu Coastal Area, China. The average abundance of microplastics in the surface water and sediment were 0.0998 ? 0.0720 items/m3 (using a trawl with 333-?m mesh)and 0.1858 ? 0.0927items/g, respectively. The concentration of microplastics showed a distribution trend of high near shore and low far shore in the east-west direction, and were the highest in the southernmost part. According to microplastics found in the surface water, the results of a quantitative source apportionment indicate that the most common source in the northernmost and southernmost regions were clothing fibers, accounting for 38.40% and 40.44% of the total source, respectively. While the major source type in the middle region was the decomposition of hard, large plastic waste. Finally, we suggested some control measures for the main types of microplastics observed in the different regions.
