ClearMicroplastic Exposure Across Trophic Levels: Effects on the Host Microbiota of Freshwater Organisms
Researchers investigated how microplastic exposure affects the gut bacteria communities of freshwater organisms including fish, invertebrates, and crustaceans. Microplastics—particularly when combined with pesticides—altered gut microbiota composition, which could impair digestion, immunity, and overall health of freshwater species.
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.
Multi stress system: Microplastics in freshwater and their effects on host microbiota
This study examined how combined exposure to microplastics and organic chemical pollutants affects freshwater organisms through a multi-stress approach, focusing on gut microbiome changes as an indicator. Microplastic exposure in combination with other pollutants altered microbiome composition more than either stressor alone, with potential consequences for host fitness and disease resistance.
Microplastic exposure across trophic levels: effects on the host–microbiota of freshwater organisms
Researchers examined how microplastic exposure across trophic levels affects the gut microbiota of freshwater organisms, finding that microplastics alter microbial community composition and that effects can transfer through food web interactions.
Microplastics 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.
Effect of emerging pollutants on the gut microbiota of freshwater animals: Focusing on microplastics and pesticides
This review examines how microplastics and pesticides, two pollutants commonly found together in freshwater, each disrupt the gut bacteria of fish and other aquatic animals, and their combined presence can make the effects worse. Changes in gut bacteria caused by these pollutants can impair metabolism, immunity, and overall health of aquatic organisms, with potential consequences for the food chain.
Effects of microplastics on Daphnia-associated microbiomes in situ and in vitro
This study investigated how microplastic exposure alters the microbiome associated with Daphnia in freshwater, finding shifts in bacterial community composition that may affect host health and ecological function. The results suggest that microplastics can indirectly harm zooplankton by disrupting their microbial symbionts.
Microplastics in the marine environment : an ecotoxicological perspective
This doctoral thesis studied the ecotoxicology of marine plastic pollution, examining how microplastics and plastic-associated chemicals affect microbial communities, algae, and invertebrates. The work found that the plasticizer microbiome — bacteria colonizing plastic surfaces — differs from surrounding seawater and may influence how plastic-associated pollutants move through food webs.
Microplastics as an aquatic pollutant affect gut microbiota within aquatic animals
This review examined how microplastics affect the gut microbiota of aquatic animals, analyzing the roles of plastic-associated chemicals and biofilms in disrupting microbial communities from ingestion through physiological impacts.
Microplastic Exposure Across Trophic Levels: Effects on the Host-microbiota of Freshwater Organisms
Researchers found that exposure to 1 µm microplastic beads and the pesticide deltamethrin caused carry-over reductions in microbiome diversity and abundance across a three-level freshwater food chain of daphnids, damselfly larvae, and dragonfly larvae.
Effects of environmental factors on host-microbiota interactions in the guts of aquatic organisms: A review
This review synthesizes how environmental stressors — including microplastics, heavy metals, photoperiod, and aquaculture feed additives — alter gut microbiota in fish and aquatic invertebrates, identifying common patterns of microbial disruption and compromised gut barrier integrity.
Gut microbiota of aquatic organisms: A key endpoint for ecotoxicological studies
This review examines how environmental contaminants including microplastics, pesticides, heavy metals, and pharmaceuticals affect the gut microbiota of aquatic organisms. Researchers highlight that changes in gut bacterial communities can serve as sensitive indicators of pollution exposure and may have downstream effects on host fitness. The study calls for improved methodologies to better link contaminant-induced shifts in gut microbiota to measurable health outcomes in aquatic species.
Effects of microplastics on freshwater organisms: A laboratory approach
This thesis systematically examined how microplastics harm freshwater organisms both physically and by acting as carriers for chemical pollutants. The research found that both the physical presence of microplastics and the chemicals associated with them can negatively affect freshwater species.
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.
Microbiome: A forgotten target of environmental micro(nano)plastics?
This review examines how micro- and nanoplastics affect the microbiome of various organisms, an area that has received less attention than other toxicological endpoints. Researchers found that most studies focused on polystyrene particles and that exposure consistently disrupted microbiome composition, triggered immune responses, and altered enzyme activity across organisms including crustaceans, fish, and mammals. The study highlights the microbiome as an important but often overlooked target of microplastic pollution.
Plastics in our water: Fish microbiomes at risk?
This review examined how microplastics and leached plasticizers affect the gut microbiomes of freshwater and marine fish, summarizing evidence for dysbiosis and reduced microbial diversity and discussing potential consequences for fish immunity, metabolism, and environmental fitness.
From plankton to fish: The multifaceted threat of microplastics in freshwater environments
This review summarizes how microplastics harm freshwater organisms from tiny plankton to fish through oxidative stress, inflammation, DNA damage, gut microbiome disruption, and metabolic disorders. Microplastics often combine with other pollutants in water, making their toxic effects even worse. Since freshwater systems are a major pathway for microplastics entering oceans and our food supply, understanding these effects is critical for protecting both ecosystems and human health.
Microbiome Composition and Function in Aquatic Vertebrates: Small Organisms Making Big Impacts on Aquatic Animal Health
This review examines how microbiomes (communities of microorganisms) function in fish and marine mammals, and how environmental stressors like microplastics can disrupt them. Microplastics in water can alter the natural balance of beneficial microbes in aquatic animals, potentially affecting their health and the safety of seafood. Understanding these disruptions matters because changes in fish microbiomes could affect the quality and safety of the fish that end up on our plates.
The ecotoxicological impact of microplastics on freshwater invertebrates
This review summarizes the ecotoxicological effects of microplastics on freshwater invertebrates, finding evidence of harm including reduced feeding, growth, and reproduction across multiple species. Because invertebrates are key links in food webs, these effects could have broader consequences for freshwater ecosystems.
Microplastics and their interactions with microbiota
This review examines how microplastics interact with microbiota (the communities of microorganisms in the environment and in living bodies). Microplastics can carry harmful bacteria and disrupt the natural balance of microbial communities in soil, water, and the human gut. The disruption of gut microbiota by microplastics is particularly concerning because a healthy gut microbiome is essential for immune function, digestion, and overall health.
