ClearMicroplastic 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.
Microplastics Contamination in Wild Fish Caught from Urbanised Sepanggar River of Kota Kinabalu, Sabah
Researchers examined microplastic contamination in wild fish caught from the urbanized Sepanggar River in Malaysia, finding MPs in all sampled fish with polymer types consistent with urban runoff, domestic sewage, and fishing gear as dominant sources.
Identification of Microplastics in Water and Fish in the Brantas River, Malang City
This study identified microplastics in both water and fish tissues in the Brantas River in Malang City, Indonesia, with FTIR analysis confirming multiple polymer types, establishing baseline contamination data for this densely populated watershed. The presence of microplastics in fish is a direct human health concern given that river fish are a common protein source for local communities.
First Evidence of Microplastic Ingestion by Riverine Fish From the Freshwater of Northwest Peninsular Malaysia
Researchers found microplastics in the guts of multiple fish species from two rivers in northwest Malaysia, with some species averaging nearly 50 microplastic particles per gram of body weight. The dominant particles were fibers and fragments of polyethylene and polypropylene — findings that signal widespread contamination of freshwater food sources and raise concerns about human exposure through fish consumption.
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.
Microplasticcontaminationincommercial marine fish: A case study in Johor, Malaysia
Researchers examined four species of commercially important marine fish from waters around Johor, Malaysia, and found microplastics present in the flesh of all species sampled. Fibers and fragments were the most common particle types, with polypropylene and polyethylene being the dominant polymers identified. The findings raise concerns about human dietary exposure to microplastics through commonly consumed fish in the region.
Microplastic Contamination and Ecological Risk Assessment in Tropical Riverine Surface Water of Selangor River Basin, Malaysia
Researchers analyzed microplastic abundance and risk in the Selangor River Basin in Malaysia, collecting surface water from 25 sites and detecting 361 particles with an average density of 1.44 particles per liter. Stereomicroscopy and FTIR confirmed the presence of multiple polymer types across upstream, tributary, and downstream zones.
Microplastic contamination and ecological risk assessment in tropical riverine surface water of Selangor River Basin, Malaysia
Researchers analyzed microplastic abundance and ecological risk in surface water collected from 25 points across the Selangor River Basin in Malaysia, using stereomicroscopy and FTIR spectroscopy to identify 361 particles with an average abundance of 1.44 particles per liter. The study found microplastic concentrations increased from upstream to downstream and applied polymer hazard and ecological risk indices to assess the potential impact on aquatic ecosystems.
Tracking microplastics at the source: a comparative study of fluorescent and FTIR microscopy at a drinking water intake in the Perak River, Malaysia
Researchers measured microplastic contamination at a drinking water intake point on the Perak River in Malaysia, finding 12 different polymer types with most particles smaller than 10 micrometers. The study compared two detection methods and found that specialized infrared microscopy was more accurate at identifying microplastic types than fluorescence microscopy. Since this river water goes directly to a treatment plant for drinking water, the findings highlight the need to understand and filter out microplastics before they reach the tap.
Identificação 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.
Abundance of Microplastic in Water of Sungai Terus Desa Sungai Nibung West Kalimantan
Researchers found microplastics at an average concentration of nearly 4,830 particles per liter in coastal river waters of West Kalimantan, Indonesia, with fibers and films being the dominant forms and common polymers like polyethylene and polypropylene identified by FTIR analysis. The high concentrations in this coastal area raise concerns for aquatic ecosystems and human communities that rely on these waters.
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.
