ClearMicroplastics in freshwater ecosystems : effects and drivers
This thesis assessed how microplastic exposure affects freshwater microorganisms, macroinvertebrates, and other organisms in freshwater ecosystems, finding that microplastics are a pervasive contaminant of freshwater environments with unclear but potentially significant ecological impacts.
Investigations into the Roles of Organisms on Environmental Plastic Pollution
This thesis investigated the roles of organisms in environmental plastic pollution, examining how marine and freshwater animals ingest microplastics and how they may transfer them through food webs. The work contributes to understanding the ecological consequences of plastic contamination in aquatic ecosystems.
Environmental Impact of Microplastics in Aquatic Ecosystems: A Review of Current Research and Future Directions
This review examines microplastic pollution in aquatic ecosystems, covering chemical, biological, and ecological processes beyond simple physical contamination and identifying priority areas for future research directions.
Nano- and microplastics in the environment : presence, effects and their role as a Trojan horse for other pollutants
This thesis reviews the presence and effects of nano- and microplastics in the environment, examining how they act as carriers for other pollutants and discussing their potential health impacts on ecosystems and humans.
Examine How Microplastics and Macroplastics in Freshwater and Marine Habitats Affect Aquatic Species and Ecosystems
This review examines how both microplastics and macroplastics harm aquatic organisms and ecosystems in freshwater and marine environments, summarizing evidence of physical injury, chemical toxicity, and food web disruption.
Microplastics as a vehicle of exposure to chemical contamination in freshwater systems: Current research status and way forward
This review assessed the current state of research on microplastics as vectors for chemical contaminants in freshwater systems, evaluating evidence for and against the vector hypothesis and identifying the most important knowledge gaps, including the need for studies at environmentally realistic concentrations.
Microplastics in freshwater systems: A review on occurrence, environmental effects, and methods for microplastics detection
This review summarizes the current understanding of microplastic contamination in freshwater systems, from sources like wastewater treatment plants to their effects on aquatic life. Researchers note that microplastics can carry toxic chemicals and have been shown to cause intestinal damage and metabolic changes in fish. The paper highlights that freshwater microplastic pollution is a significant and growing concern that warrants more research attention.
Microplastics as vectors of chemical contaminants and biological agents in freshwater ecosystems: Current knowledge status and future perspectives
This review examines how microplastics in freshwater ecosystems act as carriers for chemical pollutants and harmful microorganisms. Researchers found that pollutant concentrations on microplastic surfaces can be up to six times higher than in surrounding water, amplifying exposure risks for aquatic life and potentially humans. The findings highlight that microplastics are not just a pollution problem themselves but also a vehicle that spreads other contaminants through the food web.
Do microplastics mediate the effects of chemicals on aquatic organisms?
This review examined whether microplastics act as vectors for chemical contaminants in aquatic organisms, finding that while chemicals can sorb to microplastics, the evidence for microplastics significantly enhancing chemical toxicity in natural settings remains limited.
Effect assessment of nano- and microplastics in freshwater ecosystems
This doctoral thesis assessed the effects of nano- and microplastics on freshwater ecosystems, from individual species to community-level impacts. Freshwater sediments are known to accumulate these particles, and the research addresses critical gaps in understanding how long-term exposure at realistic concentrations affects aquatic communities.
Distribution, biological effects and biofilms of microplastics in freshwater systems - A review
This review examines microplastic distribution, biological effects, and biofilm formation in freshwater systems, highlighting knowledge gaps compared to marine studies and the ecological risks posed by microplastics as vectors for pathogens and pollutants.
The Harmful Effects of Microplastic Pollution on Aquatic Organisms
This review summarized evidence on the harmful effects of microplastic pollution on aquatic organisms in both marine and freshwater environments, covering ingestion, entanglement, and chemical toxicity pathways. The paper highlighted how the lightweight, durable, and widespread nature of plastics makes them a pervasive threat to aquatic biodiversity.
Microplastics as an Emerging Threat to the Freshwater Fishes: a Review
This review examines microplastics as an emerging threat to freshwater fishes, covering their sources from cosmetics and plastic debris fragmentation, routes of entry including wastewater treatment plants, and documented toxic effects on fish physiology and behavior.
Microplastics as contaminants in freshwater environments: A multidisciplinary review
This multidisciplinary review covers microplastic sources, abundance, composition, transport, and biological effects in freshwater systems globally, arguing that freshwater environments are both major conduits and sinks for microplastic pollution.
First evidence of microplastics in a freshwater river and their relationship to water quality
Researchers measured microplastic concentrations in a freshwater river used for recreational purposes and found a significant relationship between microplastic abundance and water physicochemical quality parameters, along with the presence of three organic compounds, providing evidence that microplastic pollution and water quality are closely linked.
Microplastics in the environment: A critical overview on its fate, toxicity, implications, management, and bioremediation strategies
This review provides a broad overview of microplastic pollution, covering how these particles enter freshwater systems, accumulate in organisms, and carry toxic chemicals through the food chain. With approximately 360 million tons of plastic produced globally each year and only 7% recycled, microplastics have become a pervasive threat to water quality and, by extension, human health.
Microplastics in Aquatic Environments and Their Toxicological Implications for Fish
This review summarizes research on microplastic occurrence in freshwater and marine environments and the toxicological risks they pose to fish, examining both direct physical effects and the role of plastics as vectors for chemical pollutants. The authors highlight that freshwater fish are particularly vulnerable given the high loads of microplastics in rivers receiving wastewater.
Interactions of microplastics with contaminants in freshwater systems: a review of characteristics, bioaccessibility, and environmental factors affecting sorption
This review examined how microplastics act as vectors for environmental contaminants in freshwater systems, analyzing the characteristics, bioaccessibility, and environmental factors that influence pollutant sorption onto plastic particles and their potential transfer to organisms including humans.
