Study of Residual Microplastics in Freshwater and Fish of the Geum River Watershed
Original title: 금강수계 담수와 어류체내 잔류미세플라스틱 연구
AI summary Read the abstract
This Korean study examined the presence of microplastics in freshwater from the Geum River watershed and in fish tissue from that system, assessing contamination levels across aquatic food chains. The findings contribute to understanding how microplastics move from river water into organisms consumed by humans.
This study was conducted to elucidate microplastics detection of freshwater ecosystems in Geum river. Samples are collected at 6 points in freshwater, 5 points in fishes. Freshwater was sampled 100 L per each points and fish species were Opsariichthys uncirostris amurensis, Hemibarbus labeo, Pseudogobio esocinus, Zacco platypus, Micropterus salmoides and Cyprinus carpio. FTIR analyis was adopted to identify microplastic types. Extracted microplastics were PES (polyester), PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), PVC (Polyvinyl chloride) in freshwater, and PES, PE, PP, PET, PVC in fishes. Our results were expected to be used basic research information for further study in microplastics of freshwater ecosystems.

Occurrence of microplastics in the Han River and riverine fish in South Korea
AI summary Read the abstract
Researchers surveyed microplastic pollution in the Han River and its tributaries in South Korea, as well as in six species of freshwater fish. They found microplastics at all sampling sites, with polyethylene, silicone, and polystyrene being the most common polymer types. Fish intestines contained an average of 22 microplastic particles per individual, predominantly fragments, indicating widespread contamination of the freshwater food web.
Occurrence and sources of micro-plastics in various water bodies, sediments, and fishes in Ansan, South Korea.
AI summary Read the abstract
This study measured microplastic contamination in four rivers, waterways, sediments, and fish in Ansan, South Korea, finding strong correlations between plastic levels in the water and in carp and river crabs. The results confirm that microplastics transfer from aquatic environments into freshwater organisms, raising concerns about food safety for people consuming locally caught fish and shellfish.
Occurrence and characteristics of microplastics in fish of the Han River, South Korea: Factors affecting microplastic abundance in fish
AI summary Read the abstract
Microplastics were detected in 106 fish from 22 species at three sites in South Korea's Han River, with an average of 16-20 particles per individual and downstream sites showing the highest contamination, reflecting greater human activity and urban inputs near the river mouth.
Effects of micro-plastics in non-point source pollution on various water sources, sediments, and fishes
AI summary Read the abstract
This Korean study measured microplastic contamination in river water, sediment, and fish from the Ansan River, finding plastics in all sample types and correlating levels between carp and river crabs. The findings suggest that both fish and crustaceans in this river accumulate microplastics from non-point pollution sources, with potential implications for local food safety.
Tracing the invisible microplastics in river water and fish organs and its implication of riverine ecosystem integrity
AI summary Read the abstract
Researchers traced microplastics in river water and fish organs from a South Asian river system, finding widespread contamination across multiple tissue types. The study identified the plastisphere concept as a useful framework for understanding how plastic-associated microbial communities accompany microplastics through aquatic food webs.
