The combination caused greater toxicity than either contaminant alone, particularly at chronic exposure durations, indicating synergistic effects relevant to agricultural runoff contamination.
Effects of polystyrene nanoplastics and PCB-44 exposure on growth and physiological biochemistry of Chlorella vulgaris
Researchers studied the combined effects of polystyrene nanoplastics and a common industrial pollutant (PCB-44) on a freshwater green algae species over both short and long exposure periods. They found that both contaminants individually inhibited algae growth and disrupted cell functions, but their combined presence intensified the damage. The study highlights that when nanoplastics and chemical pollutants co-exist in water, they can create compounding harmful effects on aquatic organisms.

Researchers studied what happens when the antibiotic chloramphenicol and polystyrene microplastics are present together in water containing blue-green algae. The study found that the combined exposure was more toxic to the algae than either pollutant alone, disrupting photosynthesis and gene expression. The findings suggest that microplastics and antibiotics may interact in ways that amplify their harmful effects on aquatic ecosystems.
Interactive toxicity effects of metronidazole, diclofenac, ibuprofen, and differently functionalized nanoplastics on marine algae Chlorella sp.
Researchers examined the combined toxicity of common pharmaceutical drugs and nanoplastics with different surface coatings on marine algae. They found that the interaction between drugs and nanoplastics produced effects ranging from additive to synergistic, depending on the specific combination, with amine-coated nanoplastics generally causing more harm. The study highlights that real-world mixtures of pharmaceutical and plastic pollutants in oceans may pose greater risks to marine life than either contaminant alone.

Researchers exposed the marine microalga Chlorella sp. to polystyrene microplastics at concentrations of 10 and 50 mg/L, finding that even low concentrations inhibited growth and disrupted photosynthesis, while higher concentrations caused more pronounced oxidative stress.
The influence of microplastics on the toxic effects and biodegradation of bisphenol A in the microalgae Chlorella pyrenoidosa
Researchers found that polystyrene microplastics inhibited the biodegradation of bisphenol A (BPA) by the microalga Chlorella vulgaris, with combined exposure showing greater toxicity than either contaminant alone due to BPA adsorption onto microplastic surfaces.
The combined toxicity influence of microplastics and nonylphenol on microalgae Chlorella pyrenoidosa
Researchers examined the combined toxicity of nonylphenol and several types of microplastics on the freshwater microalgae Chlorella pyrenoidosa. The study found that microplastics of different polymer types and sizes interacted with nonylphenol in complex ways, affecting algal growth, chlorophyll fluorescence, and antioxidant enzyme activity, demonstrating that co-exposure to microplastics and organic pollutants can produce combined toxic effects.
Toxic effects of polystyrene nanoplastics and polycyclic aromatic hydrocarbons (chrysene and fluoranthene) on the growth and physiological characteristics of Chlamydomonas reinhardtii
Researchers tested how polystyrene nanoplastics combined with two common pollutants (chrysene and fluoranthene, found in vehicle exhaust and industrial emissions) affect green algae. The combination reduced algae growth, damaged cell membranes, and triggered oxidative stress more severely than either pollutant alone. Since algae are the foundation of aquatic food chains, this combined toxicity from nanoplastics and common environmental pollutants could have cascading effects on water ecosystems and the organisms that depend on them.
Ecotoxicological impact of virgin and environmental microplastics leachate on Chlorella vulgaris: Synergistic microbial-pollutant drivers cripple photosynthesis
Researchers compared the toxic effects of leachate from new versus environmentally weathered microplastics on a common green algae species. They found that weathered microplastics were up to 3.4 times more toxic, severely disrupting photosynthesis and introducing hundreds of bacterial species and pollutants that compounded the damage. The findings highlight that microplastics become significantly more dangerous as they age in the environment.
Evaluating the Single and Combined Effects of BMDM and PS Microplastics on Chlorella sp.: Physiological and Transcriptomic Insights
Researchers exposed the alga Chlorella sp. to a UV-absorber chemical (BMDM) and polystyrene microplastics individually and in combination, finding that combined exposure produced an antagonistic effect—less total cellular and gene expression disruption than either stressor alone.
Response mechanisms of Chlorella sorokiniana to microplastics and PFOA stress: Photosynthesis, oxidative stress, extracellular polymeric substances and antioxidant system
Researchers exposed green algae to polystyrene microplastics and PFOA (a forever chemical) both separately and together, finding that the combination was more toxic than either pollutant alone. Microplastics mainly harmed the algae by blocking light for photosynthesis, while PFOA caused oxidative damage inside cells. Since microplastics and PFAS often co-exist in polluted water, their combined effects on aquatic food chains could be greater than studies of individual pollutants suggest.
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.
Combined effect of polystyrene microplastics and dibutyl phthalate on the microalgae Chlorella pyrenoidosa
Researchers investigated the combined toxic effects of polystyrene microplastics and the plasticizer dibutyl phthalate on the microalga Chlorella pyrenoidosa. They found that smaller microplastics were more toxic than larger ones, and the interaction between microplastics and the plasticizer ranged from additive to antagonistic depending on concentration. At higher microplastic levels, the particles actually reduced the bioavailability of the plasticizer, partially offsetting its toxic effects.
Molecular mechanism for combined toxicity of micro(nano)plastics and carbon nanofibers to freshwater microalgae Chlorella pyrenoidosa
Researchers tested how microplastics, nanoplastics, and carbon nanofibers affect freshwater algae individually and in combination, finding that the combined effects were significantly worse than either pollutant alone. Nanoplastics combined with carbon nanofibers caused the most severe cellular stress, damaging cell membranes, increasing oxidative stress, and disrupting energy metabolism. Since algae form the base of aquatic food chains, this damage could cascade through ecosystems and affect the safety of water and seafood for humans.
Combinatory effects of microplastics and emerging contaminants on alga Chlamydomonas reinhardtii
Researchers exposed the green alga Chlamydomonas reinhardtii to two types of microplastics found in face washes — PVC and an acrylate copolymer — along with the preservative 2-phenoxyethanol, finding that combined exposure had distinct effects on algal growth compared to individual pollutants. This is relevant because microplastics rarely occur alone in the environment, and their interactions with other chemicals can either amplify or dampen ecological harm.
Elucidating the negatively influential and potentially toxic mechanism of single and combined micro-sized polyethylene and petroleum to Chlorella vulgaris at the cellular and molecular levels
Researchers tested the individual and combined toxicity of micro-sized polyethylene and petroleum on the green alga Chlorella vulgaris, finding that particle size, concentration, and aging all influenced toxicity. Combined exposure to both contaminants caused greater harm than either alone, also shifting microbial community composition in the experimental cultures.

Researchers investigated the combined effects of microplastics and benzo[a]pyrene on marine diatoms, finding that co-exposure altered toxicity outcomes compared to individual exposures, with effects varying depending on microplastic polymer type and size.
Microplastic-enhanced chromium toxicity in Scenedesmus obliquus: Synergistic effects on algal growth and biochemical responses
This study found that polystyrene microplastics intensified the toxic effects of chromium, a heavy metal, on freshwater algae when both were present together. The combined exposure caused greater damage to algal growth, photosynthesis, and cellular defense systems than either pollutant alone. Since algae are the foundation of aquatic food chains, this synergistic toxicity could ripple through ecosystems and ultimately affect the safety of water and food sources for humans.
Single and combined toxicity assessment of primary or UV-aged microplastics and adsorbed organic pollutants on microalga Chlorella pyrenoidosa
Researchers investigated the single and combined toxicity of polyamide microplastics with the pollutants sulfamethoxazole and dicamba on the green alga Chlorella pyrenoidosa. They found that UV-aged microplastics caused different toxic effects than pristine ones, and that microplastics altered the bioavailability and toxicity of the co-occurring pollutants. The study suggests that environmental aging of microplastics changes their interactions with other contaminants, potentially affecting aquatic organisms in complex ways.
Effects of polystyrene and triphenyl phosphate on growth, photosynthesis and oxidative stress of Chaetoceros meülleri
Researchers studied the single and combined toxicity of polystyrene microplastics and the flame retardant triphenyl phosphate on the marine diatom Chaetoceros muelleri. Both pollutants individually inhibited cell growth and increased oxidative stress, while their combined exposure produced interactive effects on photosynthesis and cell membrane integrity. The study suggests that microplastics and their associated chemical additives can jointly impact the health of marine microalgae at the base of the food web.
Combined toxicity of microplastic fibers and dibutyl phthalate on algae: Synergistic or antagonistic?
This study found that when microplastic fibers and the plasticizer DBP (a chemical commonly added to plastics) are combined, they cause more damage to freshwater algae than either pollutant alone. The combination produced a synergistic toxic effect, meaning the harm was greater than simply adding the effects of each pollutant together. Since both microplastic fibers and plasticizers are widespread in freshwater environments, their combined presence could threaten the base of aquatic food chains.
