ClearInteractions between microplastics and phthalate esters as affected by microplastics characteristics and solution chemistry
The sorption of two phthalate esters onto polystyrene, polyethylene, and polypropylene microplastics was studied under varying conditions, finding that sorption was influenced by polymer type, phthalate structure, temperature, salinity, and dissolved organic matter. The results provide mechanistic insight into how microplastics accumulate endocrine-disrupting phthalates from the environment.
Environmental occurrence and ecotoxicological risks of plastic leachates in aquatic and terrestrial environments
This review examines how chemical additives that leach out of plastics -- including hormone disruptors like BPA and phthalates -- affect organisms in both water and land environments. The chemicals' harmful effects depend on environmental conditions like temperature and UV exposure, which influence how much leaches out and how easily organisms absorb it. The findings highlight that the danger of plastic pollution extends beyond the physical particles to the toxic chemicals they release.
Microplastics: A major source of phthalate esters in aquatic environments
Researchers demonstrated that microplastics are a major source of phthalate esters in aquatic environments, with PVC products leaching the highest concentrations and environmental factors like UV exposure and salinity increasing release rates.
Toxicological interactions of microplastics/nanoplastics and environmental contaminants: Current knowledge and future perspectives
This review examines how the combined presence of micro- and nanoplastics with other environmental contaminants like heavy metals, pesticides, and pharmaceuticals affects toxicity. Researchers found that plastic particles can alter the bioavailability and toxic effects of co-occurring pollutants, sometimes increasing harm to organisms, which complicates environmental risk assessment.
From co-occurrence to co-existence and co-exposure: Associations between per- and polyfluoroalkyl substances and microplastics in the environment
This review examines the growing recognition that PFAS chemicals and microplastics frequently co-occur in the environment and may interact in ways that affect both ecological and human health. Researchers identified four major sources that emit both pollutants simultaneously and found strong evidence that PFAS can adsorb onto microplastic surfaces and be co-transported through the environment. The study calls for standardized methods and long-term studies to better understand the combined exposure risks of these two widespread contaminant classes.
Microplastics release phthalate esters and cause aggravated adverse effects in the mouse gut
Researchers investigated whether microplastics can transport and release phthalate esters (PAEs) into the mouse gut, finding that microplastics adsorbed PAEs and carried them into the intestine where they accumulated. The study suggests that microplastics acting as carriers for chemical contaminants may aggravate adverse health effects in the gut beyond what either pollutant causes alone.
Phthalate acid ester release from microplastics in water environment and their comparison between single and competitive adsorption
Microplastics release phthalate plasticizers (PAEs) into water, and this study found that release rates and adsorption behavior differ significantly between polyethylene, polypropylene, and polystyrene particles, with temperature, pH, and salinity all affecting how much chemical leaches out. When multiple PAEs were present simultaneously, competitive adsorption reduced the uptake of individual chemicals — important context for understanding the real-world chemical exposure that aquatic organisms and humans face from microplastic-contaminated water.
Environmental Co-existence of Microplastics and Perfluorochemicals: A Review of Their Interactions
This review examines how microplastics and perfluorochemicals, two widespread pollutant classes, interact when they coexist in the environment. Researchers found that microplastics can adsorb perfluorochemicals onto their surfaces, potentially altering how both pollutants move through ecosystems and affect organisms. The study highlights that the combined presence of these contaminants may pose greater environmental risks than either one alone.
Environmental behaviors of microplastics in aquatic systems: A systematic review on degradation, adsorption, toxicity and biofilm under aging conditions
Aging processes like UV irradiation and physical abrasion alter microplastic surface properties, increasing their capacity to adsorb environmental pollutants while also enhancing leaching of toxic additives like phthalates, collectively amplifying the environmental toxicity of weathered microplastics.
A critical review on the interaction of polymer particles and co-existing contaminants: Adsorption mechanism, exposure factors, effects on plankton species
This review critically examines how microplastics and nanoplastics interact with co-existing contaminants including organic pollutants, toxic metals, and nanoparticles. Researchers found that the combined toxicity depends on multiple factors including plastic size, polymer type, weathering, and the nature of the co-contaminant. The study reveals that mixture effects on plankton species vary widely, with some combinations producing synergistic harm and others showing antagonistic interactions.
Fate of microplastics and emerging contaminants: Mechanisms of interactions, bioaccumulation and combined toxicity to aquatic organisms
This review summarizes how microplastics interact with other emerging contaminants in water, finding that microplastics can absorb pollutants at concentrations up to a million times higher than surrounding water and carry them into living organisms. The combined toxicity of microplastics plus these hitchhiking chemicals is often greater than either alone, and these pollutants can reach humans through the food chain.
Microplastics and associated emerging contaminants in the environment: Analysis, sorption mechanisms and effects of co-exposure
Researchers reviewed how microplastics act as carriers for other environmental pollutants — including antibiotics, PFAS, and triclosan — absorbing them from surrounding water and potentially delivering higher doses to organisms that ingest the plastic, with combined toxicity effects that can be either amplified or reduced depending on the combination.
A review on the combined toxicological effects of microplastics and their attached pollutants
Researchers reviewed how microplastics act as carriers for other environmental pollutants — including heavy metals and persistent organic chemicals — and how these combinations produce toxic effects in organisms that are more severe than either contaminant alone. The findings highlight a complex, layered toxicity problem that affects microbes, invertebrates, and vertebrates across marine and terrestrial environments.

Toxicity of polyethylene terephthalate microplastics and dimethyl phthalate in male Sprague-Dawley rats: Insights into oxidative stress, DNA damage, and histopathological impacts
Researchers exposed male rats to polyethylene terephthalate microplastics and dimethyl phthalate, a common plasticizer, both individually and in combination over 28 days. The co-exposure group showed significantly elevated markers of oxidative DNA damage, severe liver tissue degeneration, and liver enlargement compared to controls. The study highlights the potential for synergistic health effects when microplastics and their associated chemical additives are encountered together.
Mixtures of Micro and Nanoplastics and Contaminants of Emerging Concern in Environment: What We Know about Their Toxicological Effects
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.

This review examined how PFAS and micro/nanoplastics co-occur in the environment, form interfacial adsorption complexes, and interact synergistically within organisms. The authors found that the two contaminant classes amplify each other's toxicity in co-exposure scenarios and that their shared transport pathways complicate standard risk assessment.
Combined Environmental Impacts and Toxicological Interactions of Per- and Polyfluoroalkyl Substances (PFAS) and Microplastics (MPs)
This review examines how microplastics and per- and polyfluoroalkyl substances (PFAS) frequently co-occur in the environment and interact to alter each other's environmental fate and biological effects. Researchers found that co-exposure can enhance PFAS bioaccumulation by up to 2.5-fold compared to PFAS alone, accompanied by amplified oxidative stress, immune disruption, and reproductive impairment in aquatic organisms. The magnitude and direction of combined effects depend heavily on polymer type, particle size, surface aging, and biological context.

Combined ecotoxicity of polystyrene microplastics and Di-(2-ethylhexyl) phthalate increase exposure risks to Mytilus coruscus based on the bioaccumulation, oxidative stress, metabolic profiles, and nutritional interferences
Researchers exposed hard-shelled mussels to a common plastic additive (DEHP) and polystyrene microplastics together, and found that the microplastics increased how much DEHP accumulated in the animals' digestive organs. The combined exposure disrupted the mussels' antioxidant defenses and altered their metabolic processes more than either pollutant alone. The study suggests that microplastics can amplify the harmful effects of chemical pollutants in marine organisms.
