Separation of microplastics and sediments: a comparative analysis of extracting methods
AI summary Read the abstract
This study investigated microplastic ingestion by sea turtles in the Adriatic Sea through gastrointestinal examination of stranded individuals, finding particles in the majority of examined animals. Soft, film-type plastics were most commonly ingested, suggesting misidentification as jellyfish prey.

Characterization of Ingested Plastic Microparticles Extracted from Sea Turtle Post-Hatchlings at Necropsy
AI summary Read the abstract
Researchers characterized microplastic particles extracted from sea turtle post-hatchlings at necropsy, finding that biofilm formation on particle surfaces likely caused turtles to mistake plastics for food, with particle composition reflecting nearshore plastic pollution.
Ingestion of microplastic debris by green sea turtles (Chelonia mydas) in the Great Barrier Reef: Validation of a sequential extraction protocol
AI summary Read the abstract
Researchers developed and validated a sequential extraction protocol for recovering microplastics from green sea turtle intestinal contents, finding microplastics in turtles from the Great Barrier Reef. The validated method enables more consistent and accurate assessment of microplastic contamination in sea turtles, which are both ecologically important and frequently exposed to marine debris.
Protocol optimization for microplastic analysis in sea turtles: Including the first blood digestion method
AI summary Read the abstract
Researchers developed and validated a two-step chemical digestion protocol for extracting microplastics from multiple sea turtle tissue types — including blood, for the first time — achieving recovery rates of 70–84% and providing a reproducible baseline method for studying microplastic bioaccumulation and maternal transfer in marine reptiles.
Association of ocean macroplastic debris with stranded sea turtles in the Central Gulf of Thailand
AI summary Read the abstract
Researchers retrospectively analyzed records of 388 stranded sea turtles in the Central Gulf of Thailand from 2017-2020 and examined macroplastics from the gastrointestinal tracts of 30 dead turtles and 13 beaches, finding that green turtles (Chelonia mydas) comprised the majority of strandings and that plastic ingestion and entanglement were significant mortality factors.
