RETRACTED: Microplastic pollution in intertidal sediments along the coastline of China
AI summary Read the abstract
Note: This paper has been retracted. Prior to retraction, it reported measuring microplastics in intertidal sediments at 13 coastal sites in China, finding widespread contamination with fragments and fibers. The retraction status means the specific data should not be relied upon.
RETRACTED: Microplastic contamination in Penaeid shrimp from the Northern Bay of Bengal
AI summary Read the abstract
Researchers examined microplastic contamination in two species of commercially important shrimp from the Northern Bay of Bengal in Bangladesh. They found microplastics in the gastrointestinal tracts of both species, averaging about 3.4 to 3.9 particles per gram, predominantly black filaments and fibers made of polyamide and rayon. Note: this paper has been retracted by the journal.
A Quantitative Analysis of Microplastics in the Gastrointestinal Tracts of Odontocetes in the Southeast Region of the United States
AI summary Read the abstract
Researchers quantified microplastic accumulation in the gastrointestinal tracts of toothed whales from the southeastern United States. The study found microplastics present in all examined specimens, indicating that these marine mammals are routinely ingesting microplastic particles from their ocean environment.
Field measurements reveal exposure risk to microplastic ingestion by filter-feeding megafauna
AI summary Read the abstract
Researchers combined ocean microplastic data with high-resolution whale feeding measurements to estimate how much plastic blue, fin, and humpback whales ingest in the California Current Ecosystem. They found that whales likely consume millions of microplastic particles per day, primarily through contaminated prey rather than direct filtration of water. The study reveals that filter-feeding whales face far greater microplastic exposure than previously estimated.
RETRACTED: Microplastics occurrence in commercial crab (Portunus segnis) from the western coast of India and pollution indices: First investigation and evidence
AI summary Read the abstract
This retracted study investigated microplastic contamination in commercial crabs (Portunus segnis) from fishing harbors in Gujarat, India, finding an average of 0.82 +/- 0.58 MPs/g and 2.02 +/- 1.48 MPs/individual, with ATR-FTIR used to confirm polymer composition. The paper has since been retracted from the literature.
