Microplastics Absent From Reef Fish in the Marshall Islands: Multistage Screening Methods Reduced False Positives

January 24, 2024

No plastic >1 mm were found in the Republic of the Marshall Islands reef fish, reassuring human consumers.

Island communities, like the Republic of the Marshall Islands (RMI), depend on marine resources for food and economics, so plastic ingestion by those resources is a concern. The gastrointestinal tracts of nine species of reef fish across five trophic groups (97 fish) were examined for plastics >1 mm.
