Summary

Researchers tested two methods to identify whether foraminifera — tiny single-celled marine organisms — incorporate microplastics into their shells when building them from sediment particles. If confirmed, foraminifera could serve as a long-term biological record of microplastic contamination in ocean sediments going back decades.

Foraminifera are single-celled organisms found in marine environments that play...
