ClearFish diversity of Dahaura Lake, Bahraich, U.P.
Researchers investigated fish diversity in Dahaura Lake, Bahraich (Uttar Pradesh, India), recording 28 fish species belonging to 21 genera, 15 families, and 7 orders under a mopping survey programme, with Siluriformes (9 species) and Cypriniformes (7 species) as the dominant orders in this wetland ecosystem.
Using aquatic insects as indicators of microplastic pollution in rice field 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 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.
Microplastics pollution: An emerging threat to freshwater aquatic ecosystem of India
This review examined microplastic pollution as an emerging threat to freshwater aquatic ecosystems in India, discussing sources, distribution, ecotoxicological effects on aquatic biota, and potential human health hazards. The authors highlighted that while marine microplastic research is extensive, freshwater ecosystems in India remain critically understudied relative to the scale of contamination.
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.
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.
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.
Occurrence Of Microplastics in Immature Aquatic Insects of Gua Musang Tributaries in Kelantan
Researchers investigated the presence and abundance of microplastics in freshwater immature aquatic insects, specifically caddisfly (Trichoptera) and dragonfly (Odonata) larvae, collected from two tributaries of Gua Musang in Kelantan, Malaysia. The study found that microplastics had accumulated in these larvae, raising concerns about microplastic transfer through aquatic food chains in the region.
Microplastics in Freshwater Ecosystems in India: A Comprehensive Review
This review examines the occurrence, sources, and ecological risks of microplastics across freshwater ecosystems in India, synthesizing current literature on contamination levels in rivers, lakes, and other inland water bodies.
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.
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.
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.
Sources and Impact of Microplastic Pollution in Indian Aquatic Ecosystem: A Review
This review examines sources and impacts of microplastic pollution across Indian aquatic ecosystems, documenting widespread contamination in marine and freshwater environments and discussing risks to living organisms given projections that ocean plastic will outweigh fish by 2050.
Microplastics abundance in abiotic and biotic components along aquatic food chain in two freshwater ecosystems of Pakistan
Researchers quantified microplastic abundance across multiple trophic levels in two Pakistani freshwater ecosystems, finding evidence of bioaccumulation along the food chain from water and sediment through invertebrates to fish species.
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.
Microplastic contamination in freshwater ecosystems: The Hiren-2 Reservoir case study from Gujarat, India
Researchers examined the distribution, composition, and abundance of microplastics in the Hiren-2 Reservoir in Gujarat, India, finding microplastic concentrations ranging from 1.756 to 5.422 particles per liter. The study characterized microplastic contamination in a freshwater reservoir representing a growing concern for drinking water quality and aquatic ecosystem health in South Asia.
