ClearSpatiotemporal and vertical distribution characteristics and ecological risks of microplastics in typical shallow lakes in northern China
Researchers studied how microplastics are distributed across water, the viscous sublayer, and sediment layers in Baiyangdian, a shallow lake in northern China, during both wet and dry seasons. They found that microplastic abundance was highest in residential areas and that the vertical distribution pattern reversed between seasons. The study highlights that seasonal water level changes significantly affect where microplastics accumulate in shallow lake ecosystems.
[Occurrence Characteristics and Influencing Factors of Microplastics in Surface Water, Sediments, and Benthic Macroinvertebrates in Huangbai River].
This Chinese study examined microplastic contamination across water, sediment, and bottom-dwelling invertebrates in the Huangbai River, finding widespread pollution at all levels. On average, each invertebrate contained roughly 2 microplastic particles, mostly fiber-shaped and under 500 micrometers. The feeding behavior of different invertebrate groups — whether they filter water, shred debris, or scrape surfaces — influenced how many microplastics they accumulated, showing that diet and ecology shape exposure. The findings demonstrate that microplastics are moving through freshwater food webs, not just sitting in the water or sediment.

Microplastics were found across functional feeding groups and habitat types of freshwater macroinvertebrates in an Italian river, with collector-gatherers and sediment-dwelling species showing higher contamination, confirming that dietary and behavioral ecology shapes microplastic exposure patterns in invertebrate communities.
Sediment trapping – An attempt to monitor temporal variation of microplastic flux rates in aquatic systems
Researchers tested sediment trapping as a tool to monitor temporal variation in microplastic influx in an urban boreal lake, conducting a one-year monitoring program that revealed differences in microplastic flux rates between growing season and winter periods including a spring flood event.
Microplastic loads within riverine fishes and macroinvertebrates are not predictable from ecological or morphological characteristics
Researchers measured microplastic loads in riverine fish and macroinvertebrates and found that particle counts were not reliably predicted by species ecology or morphology, suggesting that individual variation and local environmental factors play a larger role in microplastic ingestion than feeding guild or habitat alone.
Size-selective microplastic uptake by freshwater organisms: Fish, mussel, and zooplankton
Researchers assessed microplastic ingestion by organisms at different trophic levels in the polluted Susurluk River Basin in Turkey, including zooplankton, mussels, and fish. The study found that while no microplastic ingestion was observed in zooplankton, both mussels and fish contained microplastics, with size-selective uptake patterns varying across organism types.
Microplastic distribution and migration in soil, water and sediments in Caohai Lake under the different hydrological periods, Southwest China
Researchers investigated microplastic distribution in soil, water, and sediments of Caohai Lake in southwest China during dry and wet seasons. They found that all environmental compartments were contaminated with microplastics, with particle types and abundance varying between hydrological periods. The study suggests that seasonal water level changes influence how microplastics migrate and distribute across lake ecosystems.

Researchers used aquatic insect communities as bioindicators of microplastic pollution in rice field ecosystems, comparing insect diversity and abundance across fields with different levels of plastic contamination. Insect assemblages responded sensitively to microplastic loads, demonstrating their potential as low-cost monitoring tools.
Distribution and characteristics of microplastics in 16 benthic organisms in Haizhou Bay, China: Influence of habitat, feeding habits and trophic level
Researchers examined microplastic contamination in 16 species of bottom-dwelling marine organisms in Haizhou Bay, China, and found plastics in every species tested, averaging about 9 particles per individual. The type of habitat, feeding strategy, and position in the food chain all influenced how much microplastic each species accumulated. The study confirms that benthic organisms are reliable indicators of microplastic pollution and that contamination is at a moderately high level by international standards.
Variability in the drivers of microplastic consumption by fish across four lake ecosystems
Researchers examined microplastic consumption by three fish species across four lakes in Minnesota and found that ingestion rates varied by species and feeding strategy. Filter-feeding fish consumed microplastics at rates that matched local water contamination levels, while visual feeders did not show the same pattern. The findings indicate that a fish's feeding behavior plays a major role in determining its microplastic exposure.

Researchers studied the feeding biology and diet-associated microplastic contamination of selected fish species, finding that feeding habits directly influence the quantity and type of microplastics ingested. The results demonstrate that trophic position and prey preferences are key predictors of microplastic exposure in wild fish.
The role of habitat preference and feeding strategy on exposure to microplastic pollution in freshwater fish species
Researchers examined microplastic contamination in water, sediment, and four commercially important fish species from the Yamula Reservoir in Turkiye. They found that bottom-feeding carp had the highest microplastic burden, while surface-feeding fish had the lowest, indicating that habitat and feeding behavior strongly influence exposure. The most common polymer found was polypropylene, and the study highlights reservoirs as understudied but significantly affected ecosystems.
Spatial and temporal distribution characteristics of microplastics in surface water of typical shallow lake in the middle and lower reaches of Yangtze River: A case study of Lake Baoan, Hubei Province
A seasonal sampling campaign at Lake Baoan, a shallow Yangtze River basin lake in China, found an average microplastic abundance of about 16 particles per litre in surface water, with fibers making up 40% of particles and polyethylene the dominant polymer. Microplastic concentrations peaked in winter and were lowest in summer, but showed no significant correlation with conventional water-quality indicators — suggesting that standard water-quality monitoring will miss microplastic contamination.
