ClearIdentificação de polímeros de microplásticos encontrados no trato digestivo de peixes do Lago de Amatitlán, Guatemala
Using FTIR-ATR spectroscopy, 68 microplastics from the gastrointestinal tracts of 36 fish from Lake Amatitlán, Guatemala were identified and characterized, representing 10% of the total extracted particles. The Portuguese-language study determined the predominant polymer types and likely contamination origins in fish from this Central American lake ecosystem.
Quantification and Characterisation of Microplastics in Fish and Surface Water at Melayu River, Johor
Researchers quantified and characterized microplastics in fish gastrointestinal tracts and surface water from Melayu River, Johor, using density separation and ATR-FTIR spectroscopy. They found microplastics in all three fish species sampled, with fibers dominant in fish and films dominant in water, and identified PET and polyethylene as the primary polymer types.
Microplastic contamination in fresh fish: insights from wet market in Selangor, Malaysia
Researchers examined microplastic contamination in the gut and muscle tissue of four commercially important fish species from a Malaysian wet market, using ATR-FTIR spectroscopy for polymer identification. Microplastics were detected in all species, with the highest abundance found in the gut of Lutjanus erythropterus, raising food safety concerns.
Identification and Characterization of Micro and Mesoplastics Isolated from Commercially Important Marine Fishes of Pulicat Lake, Tamil Nadu, India
This study identified micro- and mesoplastics in the digestive tracts of 15 commercially important fish species from an Indian coastal lake, using infrared spectroscopy to confirm plastic polymer types. The presence of plastics in food fish raises concerns about human dietary exposure through seafood consumption.
Microplastics in Nile tilapia (Oreochromis niloticus) from Lake Amatitlán
Microplastics were found in Nile tilapia from Lake Amatitlan, Guatemala, with fibers as the dominant type, confirming that even fish from lakes receiving untreated wastewater in Central America are contaminated and that the fish represent a potential vector for human microplastic ingestion.
Additives, plasticizers, small microplastics (<100 μm), and other microlitter components in the gastrointestinal tract of commercial teleost fish: Method of extraction, purification, quantification, and characterization using Micro-FTIR
Researchers developed a Micro-FTIR extraction and identification method for small microplastics (under 100 µm) and plastic additives in the gastrointestinal tracts of five commercial Mediterranean fish species, finding species-specific contamination patterns with anchovies and sardines showing the highest microplastic burdens.
Assessment of Microplastics in Fish GI Tracts and Shallow Water Sediments in Pugad Baboy Mangrove Area, Kawit, Cavite Using Fourier Transform Infrared-Attenuated Total Reflectance Spectroscopy
Researchers assessed, characterized, and quantified microplastic contamination in fish gastrointestinal tracts and shallow water sediments from the Pugad Baboy Mangrove area in Kawit, Cavite using FTIR-ATR spectroscopy to identify polymer types.
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.
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.
Validation of an imaging FTIR spectroscopic method for analyzing microplastics ingestion by Finnish lake fish (Perca fluviatilis and Coregonus albula)
Researchers developed and validated an imaging FTIR spectroscopy method for identifying microplastics ingested by Finnish lake fish, including perch and vendace. 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.
Mikroplastik Dalam Saluran Perncernaan Ikan Di Waduk Jatigede
Researchers analyzed the presence of microplastics in the digestive tracts of fish caught in Jatigede Reservoir, which receives water and contaminants including microplastics from the Cimanuk River. Fish samples from fishermen, collectors, and fish farmers were dissected and their stomach and intestinal contents were examined using FTIR spectroscopy to identify and characterize ingested microplastics.
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.
Microplastics in Commercial Fishes and By-Catch from Selected FAO Major Fishing Areas of the Southern Baltic Sea
Researchers found microplastics in both edible and non-edible organs of five fish species from the southern Baltic Sea, with 1-12 particles per fish dominated by fibers, and polymers including cellophane, polyamide, polyethylene, and polypropylene identified by FTIR spectroscopy.
