Data for: Microplastic and artificial cellulose microfibers ingestion by reef fishes in the southwestern Atlantic

AI summary Read the abstract

This dataset supports a study that found 21 reef fish species from the southwestern Atlantic had ingested microplastics or artificial cellulose microfibers. Nine species ingested particles in total, with most ingesting both plastic and cellulose types, documenting widespread microfiber contamination in Atlantic reef fish.

This study evaluated the ingestion of microplastic and artificial cellulose by 103 specimens belonging to 21 reef fish species from the southwestern Atlantic. Nine species ingested particles- seven species both types and three only one kind.

Microplastic occurrence in 21 coastal marine fish species from fishing communities on Viti Levu, Fiji

AI summary Read the abstract

Researchers analyzed microplastic ingestion in 184 fish from 21 species across three coastal communities in Fiji and found microplastics in 74% of fish examined. Fibers were the most common particle type at 66%, with polyethylene and polypropylene the dominant polymers. This dataset, the largest of its kind for Fiji, establishes a critical baseline for monitoring plastic pollution in the region's coastal fishing grounds.

Microplastic ingestion data for 86 fish species across five Vanuatu communities: a reference for Pacific Island pollution monitoring

AI summary Read the abstract

Researchers documented microplastic ingestion in 354 fish across 86 species from Vanuatu's coastal communities, establishing the country's first baseline dataset and finding that only about 5% of fish contained microplastics, mostly fibers made of polyethylene. Because Pacific Islanders often eat whole fish including the gut, this dataset is especially important for assessing human microplastic exposure through traditional food practices.

Microplastic ingestion by pelagic and benthic fish and diet composition: A case study in the NW Iberian shelf

AI summary Read the abstract

Researchers found microplastics in 78% of fish examined across four pelagic and benthic species from the NW Iberian shelf, with ingestion rates varying by feeding ecology and habitat depth, and identified predominantly fibers and fragments in gastrointestinal contents following alkaline tissue digestion.
