ClearParticulate matter and nanoplastics: synergistic impact on Artemia salina
Combining nanoplastics with particulate matter (airborne or aquatic fine particles) produces worse outcomes for the brine shrimp Artemia salina than either pollutant alone, reducing survival and vitality. This synergistic toxicity is important because in real environments, nanoplastics rarely exist in isolation — they co-occur with other pollutants, making risk assessments based on single-contaminant studies likely to underestimate harm.
Synergistic impact of nanoplastics and nanopesticides on Artemia salina and toxicity analysis
Researchers studied how polystyrene nanoplastics interact with nanopermethrin, a nano-sized pesticide, and their combined toxic effects on brine shrimp. The study found that nanoplastics acted as carriers for the pesticide, and the combination was significantly more toxic than either substance alone, lowering the lethal concentration from 4.5 to 3.1 mg per liter. These findings suggest that nanoplastics in the environment can amplify the harmful effects of pesticides on aquatic organisms.
Toxicity of polystyrene nanoplastic and copper oxide nanoparticle in Artemia salina: Single and combined effects on stress responses
Researchers tested polystyrene nanoplastics and copper oxide nanoparticles individually and in combination in brine shrimp (Artemia salina) and found synergistic toxicity — the combined exposure caused greater growth inhibition, oxidative stress, and cholinesterase disruption than either contaminant alone.

Researchers exposed a freshwater fish species to nanoplastics and a fluorinated chemical pollutant, both alone and in combination, and found that the mixture caused more severe tissue damage than either substance alone. The combined exposure harmed gills, liver, and intestines while disrupting antioxidant systems and gut bacteria. The study suggests nanoplastics can worsen the effects of industrial chemicals on aquatic life.
The interfacial interaction between Dechlorane Plus (DP) and polystyrene nanoplastics (PSNPs): An overlooked influence factor for the algal toxicity of PSNPs
Researchers investigated how a flame retardant chemical called Dechlorane Plus interacts with polystyrene nanoplastics and found that the two pollutants bind together and become more harmful to algae than either one alone. When exposed to both contaminants simultaneously, algae showed reduced photosynthesis, greater growth inhibition, and significantly increased oxidative damage. The study suggests that the combined effects of nanoplastics and their chemical additives pose greater environmental risks than previously recognized.
Interactive effect of nanoplastic particles and phototoxicant on microalgae
Researchers studied the combined effects of polystyrene nanoparticles and methylene blue, a phototoxic compound, on two species of freshwater microalgae.

The study highlights that nanoplastics can modify the toxicity of other pollutants in complex and sometimes unpredictable ways.
Nanoplastics increase the toxicity of a pharmaceutical, at environmentally relevant concentrations – A mixture design with Daphnia magna
Researchers found that polystyrene nanoplastics significantly increased the toxicity of the pharmaceutical diphenhydramine to Daphnia magna water fleas at environmentally relevant concentrations. The combination caused oxidative damage that was not observed when organisms were exposed to either substance alone, indicating a synergistic interaction. The study highlights that the co-occurrence of nanoplastics and pharmaceutical pollutants in water may create compounding risks for aquatic organisms.
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.

Researchers investigated the individual and combined toxicity of fluorescent polystyrene nanoplastics and chromium(III) nitrate nonahydrate on the marine crustacean Artemia salina. The study found that interaction between the two contaminants in seawater formed micron-sized particles and altered nanoplastic fluorescence, suggesting that co-exposure may change the bioavailability and toxic potential of these pollutants in marine environments.
A combined toxicological impact on Artemia salina caused by the presence of dust particles, microplastics from cosmetics, and paracetamol
Researchers exposed brine shrimp to a combination of dust particles, cosmetic microplastics, and paracetamol to study their combined toxicity. The findings indicate that multiple pollutants together caused greater harm than any single pollutant alone, reducing hatching rates, survival, and antioxidant defenses, which highlights how real-world mixtures of contaminants can amplify damage to aquatic life.
Polystyrene nanoplastic and engine oil synergistically intensify toxicity in Nile tilapia, Oreochromis niloticus
This study found that polystyrene nanoplastics and engine oil together caused much worse damage to Nile tilapia fish than either pollutant alone, triggering severe inflammation, blood cell changes, and oxidative stress. The combined exposure overwhelmed the fish's natural defenses and caused significant organ damage. Since tilapia is a widely consumed fish, this research highlights how mixtures of pollutants in waterways could compound health risks for both aquatic life and humans who eat contaminated seafood.
Combined Toxicity of Polystyrene Nanoplastics and Pyriproxyfen to Daphnia magna
Researchers evaluated the combined toxic effects of polystyrene nanoplastics and the insecticide pyriproxyfen on the water flea Daphnia magna under both acute and chronic exposure conditions. They found that nanoplastics initially reduced the acute toxicity of the pesticide within 24 hours but worsened chronic effects over longer periods. The study suggests that nanoplastics can alter how other environmental contaminants affect aquatic organisms, complicating risk assessments.
Comparative toxicity of polystyrene, polypropylene, and polyethylene nanoplastics on Artemia franciscana nauplii: a multidimensional assessment
Researchers compared the toxic effects of three common plastic types — polystyrene, polypropylene, and polyethylene — in nanoplastic form on brine shrimp larvae. They found that all three types caused harm, but polystyrene nanoplastics were the most toxic across multiple biological measures. The study provides the first direct comparison showing that the chemical composition of nanoplastics significantly influences their toxicity to aquatic organisms.

Researchers investigated the individual and combined effects of polystyrene nanoplastics and the industrial chemical nonylphenol on the zebrafish nervous system over 45 days. Both substances induced oxidative stress and disrupted neurotransmitter systems, with combined exposure generally producing more severe effects on glutamate metabolism and brain tissue damage. The study suggests that the interaction between nanoplastics and co-occurring environmental pollutants can amplify neurotoxic effects in fish.
The Effects of Single and Combined Exposure to Polystyrene Nanoplastics and Copper on the Behavior of Adult Zebrafish
Researchers studied how polystyrene nanoplastics and copper ions affected zebrafish behavior when the fish were exposed to both pollutants simultaneously. The combination was more toxic than either pollutant alone, reducing the concentration needed to kill fish by up to 32%. Since nanoplastics and heavy metals commonly occur together in polluted water, their combined effects on aquatic life could increase the risks associated with consuming contaminated fish.

This review examines what is known about the toxicological effects of micro- and nanoplastic mixtures combined with other emerging contaminants in the environment. Researchers found that most studies fail to calculate proper interaction parameters, making it difficult to determine whether combined exposures produce additive, synergistic, or antagonistic effects on organisms.
Influence of polystyrene nanoparticles on the toxicity of tetrabromobisphenol A in human intestinal cell lines
When human intestinal cells were exposed to both polystyrene nanoparticles and the flame retardant TBBPA together, the chemical pollutant dominated the toxic response, causing oxidative stress, DNA damage, and disruption of mitochondrial function. The study shows that mixing microplastics with other contaminants can produce complex, hard-to-predict health effects in gut cells, which matters because people are routinely exposed to multiple pollutants at once.
