ClearNanoplastics modulate the outcome of a zooplankton–microparasite interaction
Researchers found that nanoplastics can alter the outcome of zooplankton-microparasite interactions, demonstrating that plastic pollution at the nanoscale may disrupt host-parasite dynamics in freshwater ecosystems with cascading ecological effects.
Trophically Transmitted Parasites and Their Responses to Microbial Pathogens and Consumed Plastic Contaminants
Researchers reviewed how trophically transmitted parasites respond to stressors including microplastic contaminants and microbial pathogens, finding that plastic exposure can disrupt host-parasite dynamics by altering host microbiomes and immune responses. The interactions add complexity to understanding parasite infection success in polluted environments.
Size Matters: The Effects of Polystyrene Nanoplastics on Parasite Transmission in the Daphnia‐Metschnikowia Host–Parasite System
Researchers investigated how polystyrene nanoplastic size affects parasite transmission between aquatic hosts, finding that nanoplastic size influenced infection dynamics by altering host behavior, immune function, or parasite infectivity. Smaller nanoplastics had more pronounced effects on parasite transmission success.
Plastic pollution and parasitism: Impact of nanoplastics on the transmission of a marine trematode parasite
A three-month experiment showed that nanoplastics at 20 mg/L reduced cercarial emergence and survival in a marine trematode parasite infecting snails and amphipods, suggesting high nanoplastic concentrations can disrupt parasite transmission dynamics in coastal marine ecosystems.
Polystyrene nanoplastics differentially influence the outcome of infection by two microparasites of the host Daphnia magna
Researchers exposed the water flea Daphnia magna to two different parasites in the presence of polystyrene nanoplastics. The study found that nanoplastic exposure dramatically increased infection rates by a fungal parasite while having no significant effect on a gut microsporidium, suggesting that nanoplastics can differentially affect host-parasite relationships and potentially favor parasite coexistence in aquatic environments.
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.
Effects of micro- and nanoplastics on aquatic ecosystems: Current research trends and perspectives
This review covers 83 studies on the distribution and toxic effects of micro- and nanoplastics in both marine and freshwater ecosystems worldwide. Researchers found that these tiny particles affected the growth, development, behavior, reproduction, and survival of a wide range of aquatic organisms. The paper identifies key research gaps and suggests future directions for understanding the full ecological impact of plastic pollution in aquatic environments.
Interactive effects of micro/nanoplastics and nanomaterials/pharmaceuticals: Their ecotoxicological consequences in the aquatic systems
Researchers reviewed how micro- and nanoplastics interact with co-occurring nanomaterials and pharmaceuticals in aquatic environments, finding that plastics act as vectors that can either amplify or attenuate the bioavailability and toxicity of these contaminants depending on species, trophic level, and environmental conditions.
Interactions of Microplastics with Freshwater Biota
Researchers reviewed how microplastics affect freshwater animals, finding that toxicity depends on a complex mix of factors including plastic type, size, shape, chemical additives, and microbial coatings — and emphasizing that future studies need to compare synthetic plastic effects against natural particles to understand what truly makes microplastics harmful.
Plastic pollution and infectious diseases
Researchers reviewed how plastic pollution contributes to the spread of infectious diseases. The study suggests that plastic debris holding water can encourage arthropod-borne diseases by providing habitats for disease vectors, and that microplastic and nanoplastic particles may also interact with pathogens in ways that affect disease transmission in both humans and livestock.
Nanoplastics diversify and reshape Daphnia microbiomes in parasite-infected and uninfected hosts
Scientists exposed water fleas (Daphnia magna) to polystyrene nanoplastics of two sizes, with and without a yeast parasite infection, and analyzed changes in their gut and body microbiomes. The smallest nanoplastics at the highest concentration caused the most dramatic shifts in bacterial communities, with effects that exceeded those caused by the parasite alone. The results suggest that nanoplastic pollution could fundamentally reshape the beneficial microbes that aquatic organisms depend on for their health.
Biological Effects and Implications of Micro- and Nanoplastics in the Aquatic Environment
This review summarizes what is known about the biological effects and implications of micro- and nanoplastics on aquatic organisms, covering a wide range of species from phytoplankton to fish. It highlights that while laboratory studies show harm at high concentrations, the effects at environmentally relevant levels are still poorly understood.

This review examines the prevalence of micro- and nanoplastics across aquatic environments and their documented toxic effects on organisms ranging from plankton to fish, including DNA damage, reproductive harm, and neurotoxicity. Researchers found clear evidence that these particles transfer through aquatic food webs and can ultimately reach humans through seafood consumption. The study calls for more research into how microplastics carrying multiple contaminants cause combined toxic effects in marine organisms.
