ClearComparison of the Composition and Abundance of Phytoplankton Based on Different Land Use in the Cisadane River, Tangerang Regency
This paper is not about microplastics; it surveys phytoplankton species composition and abundance in the Cisadane River, Indonesia, across sites with different land use types, linking community diversity to water quality parameters like pH and transparency.
Assessment of Water Quality Status, Nutrients, and Phytoplankton Communities in the Coastal Zone of East Aceh Regency, Indonesia
This study assessed seasonal water quality and phytoplankton communities along the East Aceh coast of Indonesia, examining nutrients and physical parameters. It is not about microplastics and is not relevant to microplastic research.
Spatial and Temporal Variations in Phytoplankton Community in Dianchi Lake Using eDNA Metabarcoding
This paper is not about microplastic pollution. It uses environmental DNA metabarcoding to study phytoplankton communities in Dianchi Lake, China, identifying seasonal and spatial variation in algal species and the environmental factors that drive those changes.
Spatial analysis of the influence on “microplastic communities” in the water at a medium scale
Spatial analysis of microplastic communities in Hubei Province, China found that microplastics were more abundant in rivers than lakes (average 1.74 items/L), negatively correlated with distance from residential areas, and that anthropogenic land cover increased abundance while natural vegetation decreased it.
Effect of Microplastics on Aquatic Food Chain and Food Web Altering Phytoplankton Community Structure
This review examines how microplastics affect phytoplankton community structure and how these effects propagate through aquatic food chains and food webs, with implications for nutrient cycling and ecosystem services.
Hydrodynamics regulates microbial degradation of microplastics by modulating bottom-up and top-down effects in a river-lake confluence zone
Researchers examined how hydrodynamic conditions in river-lake confluence zones regulate microbial degradation of microplastics by modulating bottom-up and top-down effects within multi-trophic microbial communities.
Effects of biofouled plastics on phytoplankton community assembling and water chemistry: pilot study and implications for freshwater environments
Researchers conducted a pilot laboratory study exposing a five-species freshwater phytoplankton community to pristine and biofouled polypropylene fragments to investigate whether plastic acts as a carrier for algal species dispersal and to assess effects on water biodiversity and chemistry in freshwater environments.
Macrophyte complexity influences habitat choices of juvenile fish
Not relevant to microplastics — this study examines how macrophyte structural complexity influences habitat selection by juvenile Mediterranean fish in littoral zones.
Effect of urbanization and water quality on microplastic distribution in Conceição Lagoon watershed, Brazil
A study of a Brazilian lagoon watershed found that urbanization significantly degraded water quality but did not clearly increase microplastic concentrations in tributary streams. Microplastic levels in the lagoon itself were correlated with indicators of wastewater discharge, and wind and rainfall influenced their distribution.
Spatial and temporal distribution of microplastics in water and sediments of a freshwater system (Antuã River, Portugal)
This study tracked the spatial and temporal distribution of microplastics in water and sediments of a freshwater lake, finding seasonal variation in microplastic concentrations and identifying local land use and runoff as key drivers of contamination patterns.
Spatio-seasonal microplastics distribution along a shallow coastal lagoon ecocline within a marine conservation unit
Researchers conducted monthly sampling along a shallow coastal lagoon ecocline in a Brazilian marine conservation unit and found seasonal variation in microplastic abundance driven by rainfall and river inputs, with polyethylene and polypropylene fibers and fragments dominating the samples.
Ecology of mesozooplankton in a subtropical coastal lagoon: composition, spatial distribution and interactions with microplastic pollution
Researchers studied mesozooplankton ecology in a subtropical coastal lagoon, examining community composition, spatial distribution, and interactions with microplastic pollution to understand how plastic contamination affects zooplankton dynamics in coastal environments.
Zooplankton exposure to microplastic contamination in a estuarine plume-influenced region, in Northeast Brazil
Researchers examined microplastic contamination in estuarine plume waters off the coast of northeastern Brazil and its relationship with zooplankton. The study found significantly higher microplastic abundance during the high rainfall season, with fibers and fragments being the dominant types, and elevated concentrations in river plume areas compared to reef-adjacent waters, indicating land-based sources as major contributors.
Evaluation of the Influence of Habitat Heterogeneity and Human Activities on the Distribution of Microbial Diversity in a High Elevation Drop River
This is a freshwater microbiology study characterizing bacterial diversity in the Huotong River across different land-use zones in China; it is not a microplastics research paper.
The Effect of Microplastics on Microbial Succession at Impaired and Unimpaired Sites in a Riverine System
Researchers compared microbial biofilm diversity on microplastic polymers and natural substrates at impaired and unimpaired riverine sites, examining how environmental nutrient loads, seasonality, and geography influence microbiome succession on plastic surfaces in freshwater ecosystems.
Variability of microplastic loading and retention in four inland lakes in Minnesota, USA
Researchers measured microplastic levels in four small lakes in Minnesota and found that watershed size and urban development were the biggest factors driving contamination. Surface water concentrations varied widely, and sediment levels did not directly correlate with what was found in the water above. The study highlights how local land use patterns influence where microplastics end up in freshwater ecosystems.
Effect of urbanization and water quality on microplastic distribution in Conceição Lagoon watershed, Brazil
Researchers assessed microplastic distribution across urbanized and non-urbanized tributaries of Conceicao Lagoon watershed in Brazil. The study found that while urbanization significantly affected water quality parameters, it did not always correspond to higher microplastic concentrations. Evidence indicates that microplastic pollution in freshwater systems is influenced by multiple factors beyond urbanization alone, complicating simple predictions about contamination patterns.
High macroplastic pollution in a subtropical urban lake affects macroinvertebrate community structure
Researchers examined the effects of high macroplastic pollution in a subtropical urban lake on macroinvertebrate communities, finding that plastic debris significantly altered benthic assemblages and reduced biodiversity in freshwater ecosystems that have received less ecological attention than marine environments.
Combined impacts of micoplastic type, concentrations and nutrient loading on freshwater communities and ecosystems
Researchers used 40 outdoor freshwater mesocosms to test the independent and interactive effects of microplastic type (conventional vs. bio-based biodegradable), particle concentration, and nutrient enrichment on pelagic community structure and ecosystem functions including phytoplankton biomass, periphyton productivity, and leaf litter decomposition, finding no significant impacts at the ecosystem scale.
The Role of Landscape Configuration, Season, and Distance from Contaminant Sources on the Degradation of Stream Water Quality in Urban Catchments
A study of a Portuguese river basin found that landscape configuration and proximity to pollution point sources both affect stream macroinvertebrate communities. Macroinvertebrates are sensitive to microplastic pollution, and their decline in contaminated streams can indicate broader ecosystem degradation.
A critical review of interactions between microplastics, microalgae and aquatic ecosystem function
This review of microplastic-microalgae interactions found that microplastics form distinct epiplastic algal communities that differ from surrounding water communities, and that the interactions are bidirectional — MP properties affect algal physiology while algal surface coatings alter MP behavior and fate.
Microalgae colonization of different microplastic polymers in experimental mesocosms across an environmental gradient
Microalgal colonization of five different microplastic polymer types was monitored in freshwater mesocosms across an environmental gradient, finding that polymer type, surface properties, and environmental conditions all influenced the biomass and community composition of epiplastic microalgal biofilms.
Ecological traits do not predict the uptake of microplastics by fishes in a Neotropical River
Researchers found that ecological traits such as feeding guild, habitat use, and body size do not reliably predict microplastic uptake in fish species from a Neotropical river, suggesting contamination patterns are driven more by local environmental conditions than by species-specific biology.
Influence of Urbanization and Seasonality on Microplastics in a Small Brazilian Inland Stream
Researchers sampled a small Brazilian inland stream upstream and downstream of an urban center during dry and rainy seasons, finding urbanization significantly increased microplastic abundance from 1.7 to 2.6 particles per liter during the dry season, while rainfall effects were less consistent.
