ClearHeatwaves increase the polystyrene nanoplastic-induced toxicity to marine diatoms through interfacial interaction regulation
Researchers found that marine heatwaves significantly worsen the toxic effects of polystyrene nanoplastics on an important ocean diatom species. The higher temperatures weakened the algal cell walls and increased nanoplastic adhesion, leading to greater membrane damage and reduced photosynthesis and carbon absorption. The findings suggest that climate change and plastic pollution together may pose a compounding threat to ocean productivity.

Researchers investigated whether ocean warming amplifies the toxicity of amine-modified polystyrene nanoplastics in the marine microalga Dunaliella tertiolecta. Elevated temperature increased nanoplastic toxicity, worsening reactive oxygen species production, oxidative stress, and cell surface changes, suggesting climate change will intensify nanoplastic hazards to marine primary producers.

Researchers studied how warming temperatures affect the toxicity of nanoplastics in water fleas over three generations. They found that elevated temperatures significantly worsened the harmful effects of polystyrene nanoplastics on growth, reproduction, and behavior. The underlying mechanism involved disruption of the animals' chitin-based exoskeleton development and energy metabolism, suggesting that climate change may amplify the ecological risks posed by nanoplastic pollution.
Meta-analysis reveals temperature increase exacerbates microplastic toxicity in freshwater invertebrates
This meta-analysis pools data from multiple studies to show that rising temperatures make microplastics more toxic to freshwater invertebrates. The combined stress of warming water and plastic pollution caused greater harm to growth, reproduction, and survival than either stressor alone, suggesting that climate change will worsen the ecological and health impacts of microplastic contamination.
Global warming and nanoplastic toxicity; small temperature increases can make gill and liver toxicity more dramatic, which affects fillet quality caused by polystyrene nanoplastics in the adult zebrafish model
Researchers exposed zebrafish to polystyrene nanoplastics at slightly elevated water temperatures and found that warming made gill and liver damage significantly worse. The combined stress of nanoplastics and higher temperatures caused more severe tissue changes and reduced fillet quality. This study suggests that as global temperatures rise, the harmful effects of nanoplastic pollution on fish and seafood quality could intensify.
Combined effects of polystyrene microplastics and thermal stress on the freshwater mussel Dreissena polymorpha
Freshwater mussels (Dreissena polymorpha) exposed simultaneously to elevated temperature and microplastics showed greater immune suppression and oxidative stress than mussels exposed to either stressor alone, suggesting climate change warming will amplify microplastic toxicity in freshwater ecosystems.
Combined effects of global warming and microplastic exposure from individual to populational levels of a benthic copepod
This study assessed the combined effects of global warming and microplastic exposure on freshwater and marine organisms across individual and population levels, examining how climate and plastic pollution interact as co-occurring stressors. Results showed that warming conditions modified microplastic toxicity in ways that suggest climate change will alter the ecological risk of plastic pollution in aquatic systems.
Combined effects of nanoplastics and elevated temperature in the freshwater water flea Daphnia magna
This study found that polystyrene nanoplastics became more toxic to water fleas (Daphnia magna) at higher temperatures, causing more oxidative stress and a greater drop in reproduction. Warmer conditions increased how much plastic the organisms absorbed and accumulated. The findings suggest that as global temperatures rise, the harmful effects of nanoplastic pollution on aquatic life could get worse, potentially affecting species that are important food sources for fish.
Polystyrene nanoplastics impact the bioenergetics of developing zebrafish and limit molecular and physiological adaptive responses to acute temperature stress
Researchers studied how polystyrene nanoplastics affect developing zebrafish under heat stress conditions and found that the combination impairs energy production at the cellular level. While nanoplastics alone did not visibly alter development, they reduced mitochondrial efficiency and limited the fish's ability to adapt to rising temperatures. The findings suggest that nanoplastic pollution could make aquatic organisms more vulnerable to the effects of climate change.
Synergistic toxic effects of polyvinyl chloride nano-plastics and the anticipated global temperature rise in Nile tilapia
Scientists found that tiny plastic particles (nano-plastics) become much more harmful to fish when combined with warmer water temperatures like those expected from climate change. The plastic and heat together damaged the fish's blood, brain function, and DNA more severely than either threat alone. This matters because humans also consume fish and are exposed to nano-plastics, suggesting we could face similar health risks as our planet warms and plastic pollution increases.
Research progress in ecotoxicology of climate change coupled with marine pollutions
This review examined how rising ocean temperatures and acidification from climate change interact with marine pollutants including microplastics, finding that combined stressors often produce worse effects than either alone. The research underscores that plastic pollution cannot be addressed in isolation from the broader context of global climate change.

A temperature-dependent three-compartment toxicokinetic model for assessing bioavailability of microplastic-associated pollutants
Researchers developed a mathematical model to predict how rising water temperatures affect the ability of microplastics to deliver toxic pollutants into the bodies of fish and other cold-blooded animals. They found that warmer temperatures significantly increased the amount of pollutant that transferred from microplastics into intestinal cells, suggesting that climate change could amplify the health risks posed by microplastic contamination in aquatic ecosystems. The model provides a new tool for identifying which combinations of microplastic type and pollutant pose the highest risk under warming conditions.

The study suggests that climate change could amplify the harmful impact of microplastic pollution on important marine organisms.
Microplastics and low tide warming: Metabolic disorders in intertidal Pacific oysters (Crassostrea gigas)
Researchers exposed Pacific oysters to environmentally relevant concentrations of microplastics during a simulated tidal cycle and then subjected them to warming during low tide. They found that microplastic exposure disrupted the oysters' metabolism and made them more vulnerable to heat stress, with effects worsening over time even at very low particle concentrations. The study suggests that microplastic pollution may reduce the ability of intertidal shellfish to cope with rising temperatures.
Microplastics increases the heat tolerance of Daphnia magna under global warming via hormetic effects
Daphnia magna exposed to microplastics under fluctuating daily temperature conditions (simulating global warming) showed increased heat tolerance compared to control animals, suggesting a complex interaction between thermal stress and microplastic exposure.
