英文摘要	Microplastic (MP) pollution in the marine environment has become a global problem. In this study, a number of 21 mollusk species (n = 2006) with different feeding habits were collected from 11 sites along the Bohai Sea for MP uptake analysis. The MPs in mollusk samples were isolated and identified by micro-Fourier Transform Infrared Spectroscopy (μ-FTIR). Approximately 91.9% of the individuals among all the collected species ingested MPs, and there was an average abundance of 3.30 items·individual-1 or 1.04 items·g-1 of wet weight. The shape of MPs was mainly fiber, and a total of 8 polymers were detected, of which rayon had the highest detection rate (58.3%). The highest abundance, uptake rate and polymer composition of MPs was observed in creeping types, suggesting that they might ingest these MPs from their food. The gastropod Siphonalia subdilatata contains the highest levels of MPs, which may increase the risk of human exposure if consumed whole without removing the digestive gland. The polymer risk level of MPs in these mollusks was Level III (H = 299), presenting harmful MPs such as polyvinyl chloride. In terms of human exposure risk, the average exposure of the Bohai Sea residents to MPs through the consumption of mollusks is estimated to be 3399 items·(capita·year)-1. Overall, this study provides a basis for the ecological and health risk assessment of MPs in mollusks collected from the coastline of China. © 2023, The Authors. All rights reserved.
