Microplastics pollution in the rivers, its source, and impact on aquatic life: a review
AI summary Read the abstract
Researchers reviewed global evidence of microplastic contamination in rivers and lakes, finding that plastic particles serve as carriers for toxic chemicals, harm aquatic life through ingestion and entanglement, and enter human food and water supplies, while also exploring plant-based plastic alternatives that could reduce future pollution.
Microplastic contamination of lakes and rivers is an emerging environmental issue. Sources, environmental fate, in-situ behaviour, concentration and harmful impacts of microplastics on aquatic life are the focus of this review paper. Present review summarises the current state of information about microplastics in riverine ecosystems around the world. The tiny plastic particles can serve as substrate as well as transporters of a variety of toxicants, including recalcitrant chemical compounds from miscellaneous sources having potential to seriously harm people's health. Further, intake and entanglement of microplastics can inflict a number of adverse bio-physico-chemical impacts on people and other living creatures. Secondary microplastics are produced by the disintegration of bigger size primary plastic particles and ultimately end up in the terrestrial and aquatic habitats. Comprehensive information on microplastic pollution in fresh water ecosystems is still limited on a single platform. This review critically addresses the microplastic pollution in rivers, sources, and its impact around the world. Further, possible replacements for plastics like modified starch, cellulose, esters of cellulose, polylactic acid etc. derived from biomass and microorganisms are also examined.

Environmental perspectives of microplastic pollution in the aquatic environment: a review
AI summary Read the abstract
Researchers reviewed how microplastics spread through freshwater and marine environments worldwide, finding they accumulate in sediments, absorb toxic chemicals, and create surfaces where antibiotic-resistant and potentially pathogenic bacteria can thrive. This pollution threat reaches even Antarctica and the deep sea, posing risks throughout aquatic food webs.
Advancement and Challenges of Microplastic Pollution in the Aquatic Environment: a Review
AI summary Read the abstract
Microplastics are now found throughout freshwater and marine environments worldwide, from surface waters to deep-sea sediments, carrying toxic chemicals and posing biotoxicity risks to aquatic organisms, yet sampling and identification methods remain inconsistent across studies. Standardizing detection protocols is urgently needed to accurately assess the full scope of microplastic contamination and its threats to aquatic ecosystems and human health via food and water.
Microplastics Pollution in Rivers
AI summary Read the abstract
Rivers serve as both reservoirs and transport highways for microplastic pollution, carrying particles from inland sources to lakes and marine environments while exposing freshwater organisms to contamination along the way. River-borne microplastics directly threaten drinking water quality and aquatic biodiversity worldwide.
Emergence of Microplastics in the Aquatic Ecosystems: Sources and Their Characteristics
AI summary Read the abstract
Researchers reviewed the sources, physical and chemical characteristics, and environmental distribution of microplastics in aquatic ecosystems, covering both primary particles from industrial and personal care products and secondary particles generated through fragmentation of larger plastics. Understanding the diversity of particle sources and properties is foundational for modeling exposure pathways and predicting which ecosystems and human populations face the greatest contamination risk.
