ClearDistribution of Microplastic in Egypt Wastewater Using Aquatic Insects as Bioindicators
Researchers used aquatic insect larvae as bioindicators to assess microplastic distribution in Egyptian wastewater systems influenced by industrial and human activity. Insects from high-pollution sites accumulated significantly more microplastics, confirming their utility as cost-effective biological indicators for tracking microplastic contamination in freshwater systems.
Aquatic insects as mediator for microplastics pollution in a river ecosystem of Bangladesh
Researchers found that aquatic insects in a Malaysian river ecosystem ingest microplastics and can transport them across ecosystem boundaries as the insects emerge from water to land, functioning as biological vectors that move plastic contamination from aquatic to terrestrial food webs.
Occurrence of microplastics in edible aquatic insect Pantala sp. (Odonata: Libellulidae) from rice fields
Researchers detected microplastics in edible dragonfly larvae collected from rice fields, finding an average of 1.34 particles per individual with fragments being the most common type, raising concerns about microplastic transfer through insect-based food chains.
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.
Diversity of caddisflies (Trichoptera), water quality factors, and microplastics in a northern Thai stream
Caddisfly (Trichoptera) diversity was examined in relation to water quality and microplastic presence, finding that plastic contamination correlates with shifts in caddisfly community composition. Because caddisflies are widely used as bioindicators of water quality, plastic pollution may compromise standard bioassessment methods.
The Invisible Threat: A Review of Microplastics in Freshwater Systems, Including Their Presence in Water, Sediment, and Aquatic Insects
This review examines the sources, spatial distributions, and ecological effects of microplastics in freshwater systems — including water, sediments, and aquatic insects — synthesizing evidence on their pervasive contamination and biological impacts across freshwater environments globally.
Occurrence and distribution of microplastics in water, sediment, and aquatic insects of the Owena River, Osun state, Nigeria
Researchers surveyed microplastic contamination in water, sediment, and aquatic insects from the Owena River in Nigeria over a 12-month period. Microplastics were found across all sample types and river sections, with fibers and fragments being the most common forms. The study suggests that aquatic insects can serve as biological indicators of microplastic pollution in freshwater ecosystems.
Freshwater insects of different feeding guilds ingest microplastics in two Gulf of Guinea tributaries in Nigeria
Scientists collected freshwater insects from two Nigerian tributaries of the Gulf of Guinea and found microplastics ingested across different feeding guilds, providing rare baseline data on microplastic contamination of African freshwater ecosystems.
Effects of anthropogenic activities on microplastics in deposit-feeders (Diptera: Chironomidae) in an urban river of Taiwan
Researchers quantified microplastic abundance and types in midge larvae (Chironomidae) from an urban river and found that multiple anthropogenic activities including industrial discharge, agriculture, and residential runoff were associated with elevated microplastic levels in these freshwater deposit-feeders.
Diversity and relative abundance of aquatic insects of Dahaura Lake, Bahraich, U.P.
This ecological survey documented aquatic insect diversity and abundance in Dahaura Lake in India over a six-month period, finding 25 genera from multiple orders. Aquatic insects are bioindicators of water quality and could be used to assess the ecological impacts of microplastic contamination in freshwater ecosystems.
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.
In Situ Effects of a Microplastic Mixture on the Community Structure of Benthic Macroinvertebrates in a Freshwater Pond
Researchers conducted an in situ mesocosm experiment adding a realistic microplastic mixture to freshwater pond sediments and monitored benthic macroinvertebrate communities over time, finding that MP exposure shifted community composition and reduced taxonomic richness at environmentally relevant concentrations.
Occurrence and physical characterization of microplastics in mangrove-dwelling Fireflies (Coleoptera: Lampyridae) of entotourism importance
Researchers examined microplastic contamination in mangrove-dwelling fireflies in Malaysia, finding microplastics in 50% of larvae and 14.8% of adults, representing one of the first studies of microplastic occurrence in this ecologically and culturally important insect group.
Assessment of microplastic accumulation in aquatic insects of different feeding guilds collected from wastewater in Sohag Governorate, Egypt
Microplastic accumulation in four freshwater insect families from an Egyptian wastewater basin found that collector-gatherers (Chironomidae and Hydrophilidae) had the highest microplastic loads and bioaccumulation factors, with polyester fibres dominant in all taxa studied.
Microplastics in freshwater sediments: Effects on benthic invertebrate communities and ecosystem functioning assessed in artificial streams
Researchers tested the effects of polyethylene microplastics on freshwater invertebrate communities in artificial streams using environmentally relevant concentrations. They found that microplastics significantly reduced the abundance of deposit-feeding and grazing organisms by 31-50%, with chironomids and mayflies showing the highest ingestion of plastic particles.
Microplastic accumulation in benthic macroinvertebrates is widespread, regardless of the river ecological status
A broad survey of freshwater benthic macroinvertebrates across multiple rivers found that microplastic accumulation was widespread regardless of local urban development levels, suggesting that factors beyond proximity to urban areas—such as river hydrology and upstream sources—drive MP exposure in freshwater invertebrates.
How microplastics influence the health and microbiota of aquatic invertebrates: A review
This review examines how microplastics affect the health and microbiota of aquatic invertebrates, an area that has received less attention than fish studies. Researchers summarize evidence showing that microplastics cause toxicity at biological and molecular levels, alter microbial communities associated with invertebrate hosts, and interact with climate change and other pollutants to produce combined effects. The study highlights significant knowledge gaps and proposes future research directions for understanding microplastic impacts on aquatic ecosystems.
Using the Asian clam as an indicator of microplastic pollution in freshwater ecosystems
Researchers proposed the Asian clam as a bioindicator species for monitoring microplastic pollution in freshwater ecosystems, building on prior findings of high contamination rates in these organisms. Using a widely distributed filter feeder as a sentinel species could help standardize freshwater microplastic monitoring the way mussels are used in marine settings.
Microplastic contamination in waterbirds and their habitats: evidence from little egrets (Egretta garzetta) in tropical rice fields
Researchers investigated microplastic contamination in little egrets and their rice field habitats in tropical southern China. They found microplastics in water, sediment, feathers, and fecal samples, with fiber-shaped particles being the most common type. The study suggests that waterbirds can serve as useful indicators of microplastic pollution levels in agricultural wetland environments.
Species-specific bioindicators of microplastic pollution in a shallow lake: Hydrological period drives benthic macroinvertebrate exposure in Baiyangdian Lake, China
Researchers studied microplastic accumulation in three benthic invertebrate species across seasons in Baiyangdian Lake, China, and found that biological factors like feeding behavior were more important than ambient microplastic levels in determining uptake. The study suggests that seasonal hydrology strongly influences microplastic exposure and recommends specific shrimp and crayfish species as sensitive bioindicators for monitoring microplastic pollution in freshwater ecosystems.
