Microplastic and nanoplastic pollution: Assessing translocation, impact, and mitigation strategies in marine ecosystems
This review examines how microplastics and nanoplastics move through marine ecosystems, contaminating species from tiny plankton to large fish through processes like biofouling and chemical leaching. The plastics interact with other environmental stressors like climate change and chemical pollution, compounding their effects on marine food webs. The authors highlight that nanoplastics, which form as microplastics break down further, may pose additional unique risks that are not yet well understood.
Toxic effects on ciliates under nano-/micro-plastics coexist with silver nanoparticles
Researchers tested the combined effects of different-sized plastic particles with silver nanoparticles on marine microorganisms and found that the mixture was more toxic than either pollutant alone. Smaller nanoplastics combined with silver nanoparticles caused the most severe damage, disrupting energy and fat metabolism and causing DNA and protein damage. This study shows how microplastics can amplify the toxicity of other environmental pollutants in marine food chains.
Charge-dependent negative effects of polystyrene nanoplastics on Oryzias melastigma under ocean acidification conditions
This study tested the combined effects of differentially charged polystyrene nanoplastics and ocean acidification on the marine fish Oryzias melastigma, finding that surface charge significantly influenced both independent and interactive toxicity. Negatively charged particles were generally more harmful, with effects exacerbated under acidified conditions.
Dual impacts of elevated pCO2 on the ecological effects induced by microplastics and nanoplastics: A study with Chlamydomonas reinhardtii
Researchers examined how freshwater acidification from elevated carbon dioxide interacts with polystyrene micro- and nanoplastics to affect a common green algae species. They found that smaller nanoplastics caused greater harm than larger microplastics, primarily through oxidative stress, while acidification alone actually promoted algal growth. The study reveals that climate change and plastic pollution can interact in unexpected ways, with acidification sometimes masking or modifying the toxic effects of plastic particles.
Biological Responses to Climate Change and Nanoplastics Are Altered in Concert: Full-Factor Screening Reveals Effects of Multiple Stressors on Primary Producers
Using high-throughput screening of a freshwater green alga, researchers tested how nanoplastics interact with multiple climate change stressors (temperature, CO2, pH, UV), finding that nanoplastics combined with warming or UV caused greater harm than either alone, and that climate change will likely amplify nanoplastic toxicity.
Nanoplastics impact on marine biota: A review
Researchers reviewed the emerging toxicological literature on nanoplastics in marine ecosystems, distinguishing primary nanoplastics (manufactured at nanoscale) from secondary nanoplastics (fragmented from larger debris), and summarizing how nanoscale size changes particle reactivity and bioavailability in ways that differ substantially from their macro- and microscale counterparts.

Interactions of Microplastics with Persistent Organic Pollutants and the Ecotoxicological Effects: A Review
This review examines how microplastics interact with persistent organic pollutants in the environment, including how factors like salinity, pH, and plastic type affect the sorption of toxic chemicals onto microplastic surfaces. The study suggests that when organisms ingest microplastics loaded with these pollutants, the chemicals can be released inside the body, posing combined ecotoxicological risks.
Impact of micro- and nano-plastics on marine organisms under environmentally relevant conditions
This review summarized the impacts of micro- and nanoplastics on marine organisms including microalgae, crustaceans, snails, and fish at environmentally realistic concentrations. Researchers found that while some species showed tolerance at low concentrations, chronic exposure to nanoplastics in particular caused oxidative stress and behavioral changes. The study emphasizes that more research using real-world concentration levels is needed to accurately assess the risks microplastics pose to ocean life.

Research progress on the interaction between climate change and marine microplastic pollution
This review examines the two-way relationship between climate change and marine microplastic pollution, finding that rising ocean temperatures, acidification, and hypoxia can accelerate plastic fragmentation and alter how microplastics are distributed and ingested by marine life. Conversely, microplastics may affect carbon cycling and plankton productivity in ways that feed back into climate dynamics. The findings highlight that microplastic risks cannot be assessed in isolation from the broader context of a changing ocean.
