ClearStudy on Plastic Ingestion in Carcasses Sea Turtles on Enggano Island, Indonesia
Researchers examined plastic ingestion in carcasses of five green turtles and five hawksbill turtles found dead on Enggano Island, Indonesia, finding that both macroplastics and microplastics were detected in 100% of individuals, with 164 macroplastic items recovered from green turtles and fragments being the dominant plastic category.
Feeding Habits and the Occurrence of Anthropogenic Debris in the Stomach Content of Marine Fish from Pattani Bay, Gulf of Thailand
Researchers found anthropogenic debris in the stomachs of 12 of 34 marine fish species from the Gulf of Thailand, with planktivorous fish ingesting the most debris and blue-colored items predominating, with ingestion rates peaking during the northeast monsoon season.
Ingestion of microplastic debris by green sea turtles (Chelonia mydas) in the Great Barrier Reef: Validation of a sequential extraction protocol
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.
Assessment of microplastic pollution in corals, seawater, and marine sediments in the Gulf of Thailand
Researchers assessed microplastic occurrence, abundance, and characteristics in coral, seawater, and sediment samples from two reef sites in the Gulf of Thailand, detecting microplastics in all coral samples at concentrations ranging from 0.24 to 2.60 particles per gram and finding spatial variability across reef species and sites.
Microplastics on beaches along the eastern Gulf of Thailand – A preliminary study
Researchers quantified microplastics at the high-tide line of 21 beaches along the eastern Gulf of Thailand, finding highly variable contamination levels ranging from 420 to over 200,000 particles per kilogram of sand.
Differential impact of marine debris ingestion during ontogenetic dietary shift of green turtles in Uruguayan waters
Researchers analyzed gut contents of 96 stranded green turtles from Uruguay and found debris in 70% of individuals, with hard plastics most abundant by weight; smaller (juvenile) turtles had significantly more debris ingestion, identifying the early juvenile life stage as particularly vulnerable to plastic pollution in the southwestern Atlantic.
Characterization of Ingested Plastic Microparticles Extracted from Sea Turtle Post-Hatchlings at Necropsy
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.
Diet-related selectivity of macroplastic ingestion in green turtles (Chelonia mydas) in the eastern Mediterranean
Green sea turtles in the eastern Mediterranean were found to ingest macroplastic debris that resembles their natural food (seagrass), suggesting diet-based selectivity drives plastic ingestion in this species. This has conservation implications for turtles whose habitat overlaps with plastic-polluted coastal areas.
Plastic Ingestion in Post-hatchling Sea Turtles: Assessing a Major Threat in Florida Near Shore Waters
Plastic fragments were found in the digestive tracts of 93% of stranded juvenile loggerhead sea turtles examined in Florida, with up to 287 fragments and a plastic-to-body weight ratio as high as 1.23%. The high ingestion rates in animals this young suggest that plastic pollution poses a serious threat to sea turtle survival from the earliest life stages.
A quantitative risk assessment framework for mortality due to macroplastic ingestion in seabirds, marine mammals, and sea turtles
Researchers analyzed over 10,000 necropsies of seabirds, marine mammals, and sea turtles to quantify the risk of death from swallowing large plastic debris. The study found that sea turtles faced the highest mortality rate at 4.4%, and the type of plastic mattered: rubber was most dangerous for seabirds, fishing debris for marine mammals, and soft plastics for sea turtles.
Occurrence and distribution of microplastics in surface sediments from the Gulf of Thailand
Researchers investigated the distribution and characteristics of microplastics in surface sediments across the Gulf of Thailand, finding an average abundance of 150.4 pieces/kg dry weight with fragment shapes dominating, and observed a correlation between sediment grain size and microplastic content. The results establish baseline contamination data for this Southeast Asian coastal region.
High frequency of micro- and meso-plastics ingestion in a sample of neonate sea turtles from a major rookery
Researchers found that 79% of neonate sea turtles washed ashore dead on Florida's Atlantic coast had ingested plastics, with microplastics being the most common type found. This high rate of plastic ingestion in very young turtles—before they have even left coastal waters—points to a severe and early-life pollution problem affecting an already threatened species.
Microplastic Occurrence in the Diet of Green Sea Turtles (Chelonia mydas) From the Coastal Region of São Paulo, Brazil
Researchers analyzed the gastrointestinal contents of 218 green sea turtles from the coast of Sao Paulo, Brazil, and detected microplastics in nearly 46% of samples. Microplastics were found in 75% of samples from the more urbanized central-south coast compared to 35% from the northern coast, suggesting that proximity to human activity significantly influences microplastic ingestion rates in marine wildlife.
Microplastics in large marine animals stranded in the Republic of Korea
Researchers analyzed microplastics in the digestive tracts of 12 stranded marine animals in South Korea, including whales, porpoises, dolphins, and sea turtles, detecting microplastic contamination across all species examined between 2019 and 2021.
Testing the factors controlling the numbers of microplastics on beaches along the western Gulf of Thailand
Researchers measured microplastic concentrations on beaches along the western Gulf of Thailand and applied statistical models to link abundance patterns to ocean surface currents and land-based pollution sources, finding that current direction and proximity to riverine inputs were the strongest predictors of beach MP levels.
Type and Distribution of Microplastic Contamination in Beach Sediment Along the Coast of the Lower Gulf of Thailand
Microplastic contamination was surveyed at five beaches along Thailand's lower Gulf Coast, with Talo Kapo showing the highest abundance and fragment-type particles being most common. The findings document baseline plastic pollution levels and polymer types across different coastal settings.
The feeding habit of sea turtles influences their reaction to artificial marine debris
Video cameras attached to sea turtles and fecal analysis showed that loggerhead and green turtles frequently encounter and ingest artificial marine debris, with debris found in over 84% of loggerhead gut contents examined. Feeding habitat and diet type influenced debris exposure — carnivorous loggerheads encountered far more plastic debris than herbivorous green turtles.
A quantitative analysis linking sea turtle mortality and plastic debris ingestion
Researchers analyzed two datasets covering hundreds of sea turtles and found a quantitative link between the amount of plastic debris ingested and the probability of death. The study estimated that ingesting as few as 14 pieces of plastic significantly increases mortality risk, providing some of the first direct statistical evidence connecting plastic ingestion volume to lethal outcomes in marine turtles.
Plastic ingestion in oceanic-stage loggerhead sea turtles (Caretta caretta) off the North Atlantic subtropical gyre
Researchers analysed gastrointestinal tracts of 24 juvenile loggerhead sea turtles (Caretta caretta) collected in the North Atlantic subtropical gyre near the Azores, finding that 20 of 24 individuals had ingested plastic debris, highlighting the vulnerability of oceanic-stage juveniles to plastic pollution.
