ClearEffect of microplastics on the toxicity of chlorpyrifos to the microalgae Isochrysis galbana, clone t-ISO
Researchers tested how polyethylene microplastics affect the toxicity of the pesticide chlorpyrifos to the marine microalga Isochrysis galbana. While microplastics alone did not impair algal growth, chlorpyrifos caused significant growth inhibition at higher concentrations. When microplastics were loaded with chlorpyrifos, they partially reduced the pesticide's toxicity by adsorbing it, though at higher pesticide doses the combined exposure still inhibited algal growth.
Microplastics reduce the bioaccumulation and oxidative stress damage of triazole fungicides in fish
Researchers found that microplastics can reduce the bioaccumulation and oxidative stress damage of triazole fungicides in fish, suggesting that microplastic-pesticide interactions may alter the expected toxicity of agricultural chemicals in aquatic organisms.
Effects of Microplastics on the Adsorption and Bioavailability of Three Strobilurin Fungicides
This study investigated how microplastics affect the adsorption and bioavailability of three strobilurin fungicides, finding that polystyrene and polyethylene microplastics reduced pesticide availability in water but altered how the fungicides accumulated in and harmed zebrafish. The results demonstrate that microplastics can change the environmental behavior of agricultural pesticides in ways that are difficult to predict.
Micro- and nanoplastics interact with conventional pollutants on microalgae: Synthesis through meta-analysis
This meta-analysis of 933 experimental assessments found that micro- and nanoplastics interact with conventional pollutants like heavy metals and pesticides on microalgae in predominantly antagonistic ways, meaning the combined toxicity was often less than expected. This occurs because plastic particles adsorb pollutants from the water, reducing their bioavailability, though the effect varies by plastic size, charge, and aging.

Researchers discovered that polyethylene microplastic particles reduced the toxicity of zinc oxide nanoparticles to marine microalgae by adsorbing the nanoparticles onto their surface, revealing that microplastics can modify the bioavailability of co-occurring contaminants.
Impact of microalgal biomass and microplastics on the sorption behaviour of pesticides in soil: a comparative study
Researchers examined how microalgal biomass interacts with microplastics to influence pesticide sorption behavior, finding that algal exudates coating MP surfaces altered their affinity for pesticides and affected the overall fate of pesticide-MP complexes in water.
Joint toxicity of microplastics with triclosan to marine microalgae Skeletonema costatum
Researchers investigated the combined toxicity of triclosan and four types of microplastics on the marine microalga Skeletonema costatum. They found that while all microplastics individually inhibited algal growth, PVC and smaller particles had the strongest effects, and the joint toxicity with triclosan followed an antagonistic pattern rather than additive or synergistic. The study suggests that microplastics can adsorb organic pollutants and partially reduce their bioavailability, though the physical damage from smaller particles remains a significant concern.
Polystyrene microplastics attenuated the impact of perfluorobutanoic acid on Chlorella sorokiniana: Hetero-aggregation, bioavailability, physiology, and transcriptomics
Researchers studied how polystyrene microplastics interact with PFBA (a type of forever chemical) when both are present around green algae. Surprisingly, the microplastics actually reduced the toxic effects of PFBA on the algae by binding to the chemical and making it less available, showing that pollutant interactions in the environment can be more complex than expected.
Microplastics decrease the toxicity of sulfamethoxazole to marine algae (Skeletonema costatum) at the cellular and molecular levels
Researchers investigated the combined toxicity of the antibiotic sulfamethoxazole and five types of microplastics on the marine alga Skeletonema costatum. They found that certain microplastics actually decreased the toxicity of the antibiotic by adsorbing it, creating a protective "shelter" effect, though polystyrene combined with the antibiotic caused higher oxidative stress. The study suggests that microplastics can alter the bioavailability and toxicity of co-occurring pollutants in marine environments through adsorption interactions.
Alleviating effects of microplastics together with tetracycline hydrochloride on the physiological stress of Closterium sp.
Researchers studied how PET and PBT microplastics combined with the antibiotic tetracycline affect freshwater microalgae. They found that in some combinations, microplastics actually reduced the toxicity of the antibiotic to the algae, likely by adsorbing the chemical onto their surfaces. The study highlights the complex and sometimes counterintuitive ways that microplastics interact with other pollutants in aquatic environments.
Polyethylene microplastic modulates the toxicity of pentachlorophenol to the microalgae Isochrysis galbana, clone t-ISO
Researchers studied how polyethylene microplastics interact with the pesticide pentachlorophenol to affect the marine microalga Isochrysis galbana. They found that microplastics modulated the toxicity of the pesticide, with the combined exposure producing different effects on photosynthetic pigments and growth than either pollutant alone. The study highlights that microplastics can alter how other environmental contaminants affect marine organisms, complicating risk assessments.
Microplastic Interference with Fipronil Toxicity to Zebrafish Embryonic Development
Researchers studied how polyethylene microplastics affect the toxicity of the insecticide fipronil on developing zebrafish embryos. They found that while microplastics reduced the lethal effects of fipronil, likely by adsorbing some of the chemical, they did not change the rate of developmental abnormalities. The study highlights the complex ways different pollutants can interact in aquatic environments.

Effect of polyethylene microplastic biodegradation by algae on their sorption properties and toxicity
Researchers studied how algal biodegradation of high-density polyethylene microplastics changes their ability to adsorb UV filter chemicals. The study found that biofilm formation on microplastic surfaces altered their sorption properties through multiple mechanisms, and that high concentrations of these microplastics inhibited algal growth and reduced protein and chlorophyll levels.
Adsorption behavior of azole fungicides on polystyrene and polyethylene microplastics
Researchers studied how polystyrene and polyethylene microplastics adsorb azole fungicides commonly used in agriculture. The study found that smaller microplastic particle sizes led to stronger adsorption capacity, and factors like pH, ionic strength, and the presence of organic acids all influenced how readily pesticides bind to microplastic surfaces.
Adsorption of azoxystrobin and pyraclostrobin onto degradable and non-degradable microplastics: Performance and mechanism
Researchers studied how two common fungicide pesticides attach to both biodegradable and conventional microplastics in soil environments. They found that non-degradable microplastics absorbed more pesticide and released it more slowly than biodegradable alternatives. The study suggests that microplastics in agricultural soil may act as reservoirs for pesticides, potentially prolonging their environmental presence and ecological impact.
Effects of Microplastics on Bioavailability, Persistence and Toxicity of Plant Pesticides: An Agricultural Perspective
This review examines how microplastics in soil interact with pesticides, generally reducing pesticide effectiveness by absorbing the chemicals onto their surfaces. While this lowers the immediate toxicity of pesticides, it also makes them last longer in the environment and may reduce pest control in agriculture, potentially affecting food production and the long-term safety of the food supply.
The combined toxicity effect of nanoplastics and glyphosate on Microcystis aeruginosa growth
Researchers found that cationic nanoplastics adsorb glyphosate so strongly that co-exposure actually reduces the herbicide's toxicity to algae by sequestering it — but the nanoplastics coated in glyphosate adhere more readily to algal surfaces, potentially concentrating both pollutants further up the food chain.
Adsorption of benzalkonium chlorides onto polyethylene microplastics: Mechanism and toxicity evaluation
Researchers investigated how polyethylene microplastics adsorb benzalkonium chloride disinfectants and the combined toxic effects on water fleas. The study found that microplastics had strong adsorption capacity for these disinfectants, and surprisingly, the presence of microplastics increased survival rates of Daphnia magna by acting as scavengers that reduced the bioavailability of the toxic chemicals in water.
Effects of single and combined exposure of virgin or aged polyethylene microplastics and penthiopyrad on zebrafish (Danio rerio)
This study found that polyethylene microplastics can increase the toxicity of a common fungicide (penthiopyrad) in zebrafish by helping the chemical build up in their bodies. The combination caused more intestinal damage and disrupted gut bacteria than either pollutant alone. This highlights an important concern: microplastics in the environment can act as carriers for pesticides, potentially amplifying their harmful effects on organisms including those in the human food chain.

Researchers investigated how polyethylene mulch film microplastics interact with pesticides in agricultural soil and their combined effects on earthworms. The study found that sorption of pesticides to mulch film microplastics actually decreased the bioavailability of two model pesticides to earthworms, suggesting that in some cases microplastics may reduce rather than increase pesticide toxicity to soil organisms.

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.
Interactions Between Various Classes of Pesticides and Microplastics
This review summarized how microplastics interact with pesticides from multiple chemical classes, covering adsorption, desorption, environmental transport, and combined toxicity. The authors found that microplastic-pesticide interactions are governed by both the plastic's surface chemistry and the pesticide's physicochemical properties, and that combined exposures often amplify toxicity beyond either contaminant alone.
