Okinawa researchers find plastic fused into dead coral rubble
Original title: New plastic pollution discovered: 'Plasticorals' coral rubble fused with plastic
Specimens 20–30 millimeters wide from Okinawa beaches contain household polymers inside coral pores.
Researchers from the Okinawa Institute of Science and Technology and the University of the Ryukyus report “plasticorals,” coral rubble fused with melted household plastic, in Marine Pollution Bulletin. Specimens came from beach surveys on Okinawa. The authors say beach bonfires are one likely source and that toxic effects on reef life still need study.
Unconfirmed: The exact origin of the plasticorals is not established; bonfires are described as one likely source.
- Each described specimen is 20–30 millimeters wide.
- Plasticorals are a type of plastiglomerate.
- The paper’s publication date is given as September 4, 2026.
- Prior studies are cited on polymer chemicals and coral pathogens.
