title: Assessment of trace element contamination derived from coastal plastic debris using gastropods, bivalves, and decapod crustaceans on Zamami-jima Island, the Ryukyu Islands: Spatial, temporal, and species-specific variation
abstract: Plastic debris in coastal environments can serve not only as a physical pollutant but also as a carrier of trace elements. In this study, we analyzed 34 elements in four coastal invertebrate species—Nerita polita (Mollusca: Gastropoda), Cellana testudinaria (Mollusca: Gastropoda), Atactodea striata (Mollusca: Bivalvia), and Coenobita purpureus (Crustaeca: Decapoda: Anomura)—collected from two stations (Nita Beach and Furuzamami Beach) on Zamami-jima Island in the Ryukyu Islands. We assessed the
