The study confirmed that wild freshwater fish are ingesting microplastics and demonstrated that standardized analytical methods are needed to improve the reliability of microplastic detection in aquatic organisms.
Identification of microplastic polymers found in the digestive tract of fish from Lake Amatitlán, Guatemala
FTIR-ATR spectroscopy was used to identify microplastic polymers extracted from the gastrointestinal tracts of 36 fish from Lake Amatitlán, Guatemala, analyzing 68 particles representing 10% of total extracted microplastics. The study determined the predominant polymer types present in fish from this lake and assessed likely contamination sources.
A comparison of microplastic contamination in freshwater fish from natural and farmed sources
Researchers compared microplastic contamination in farmed Nile tilapia and two wild-caught native freshwater fish species from Colombia, analysing stomach, gill, and flesh tissues using micro-FTIR spectroscopy. Fragments were the dominant microplastic type across all species and tissues, and contamination was found in farmed as well as wild fish, indicating that both aquaculture and natural water environments contribute to microplastic exposure in freshwater fish.
Identification and Quantification of Microplastics in Mackerel (Rastrelliger sp) at the Tual City Fish Market
Researchers identified and quantified microplastics in the digestive tracts of mackerel from the Tual City fish market in Indonesia using microscopy and FTIR analysis, confirming the presence of multiple polymer types in commercially sold fish.
Screening for microplastics in marine fish of Thailand: the accumulation of microplastics in the gastrointestinal tract of different foraging preferences
Researchers investigated microplastic ingestion in 492 marine fish (361 demersal and 131 pelagic) from Thailand, finding no significant difference in uptake between the two foraging types, with polyamide fibers dominating in both groups. FT-IR analysis confirmed polyamide as the most common polymer and red-colored fibers as the most abundant morphology, providing the first such characterization for Thai marine fish.
Spatiotemporal microplastic occurrence study of Harike wetland, A Ramsar wetland of India
Researchers conducted a spatiotemporal study of microplastic contamination in Harike wetland, India's largest Ramsar wetland, examining water, canal sediment, and gut contents of Cyprinus carpio fish using ATR-FTIR and GC-MS.
