From May to December 2024, monthly sampling was conducted at Nishinoura Fishing Port (Fukuoka, Japan), and microplastics were detected in both the digestive tracts and feces of wharf roaches. The concentrations of microplastics in both digestive tracts and feces exhibited similar seasonal trends, with a decrease during winter. Additionally, difference in the shape characteristics was observed between microplastics found in wharf roach samples and seawater. This study highlights the feasibility of using wharf roach feces as a non–invasive sample for monitoring microplastic accumulation in the coastal area, offering a potential method for assessing pollution levels in coastal environments."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410024323624773508","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Jeffrey
