ClearInteractions of emerging contaminants with model colloidal microplastics, C60 fullerene, and natural organic matter – effect of surface functional group and adsorbate properties
Researchers studied how two common pharmaceutical contaminants — amlodipine and carbamazepine — adsorb onto colloidal microplastics, natural organic matter, and fullerene nanoparticles. The drug amlodipine accumulated at much higher levels than carbamazepine, and the type of surface coating on the plastic significantly influenced how much drug was absorbed, with implications for how microplastics carry pharmaceuticals through water systems.

Adsorption of a diverse range of pharmaceuticals to polyethylene microplastics in wastewater and their desorption in environmental matrices
Researchers investigated how polyethylene microplastics adsorb pharmaceuticals in municipal wastewater and release them in environmental and biological fluids. They found that drug adsorption depended heavily on the compound's charge and hydrophobicity, with cationic and hydrophobic drugs adsorbing most readily. The study suggests that microplastics could act as vectors for certain pharmaceuticals, potentially transporting them through waterways and into organisms.

Researchers tested the sorption and desorption of three pharmaceuticals — sulfamethoxazole, propranolol, and sertraline — onto polyethylene microplastics in water, finding that all three compounds sorbed to the plastic surface and were only partially released over time. The results suggest microplastics can act as vectors for pharmaceutical compounds in aquatic environments, potentially affecting their bioavailability.
Carbon nanomaterials for co-removal of antibiotics and heavy metals from water systems: An overview
This review examines how carbon-based nanomaterials can simultaneously remove antibiotics and heavy metals from contaminated water. While the focus is on water treatment rather than human health directly, the study notes that microplastics in the environment can affect how well these cleanup methods work. The authors highlight that these advanced materials show strong potential but need further evaluation of their cost-effectiveness for real-world use.
Sorption of selected pharmaceutical compounds on polyethylene microplastics: Roles of pH, aging, and competitive sorption

Effects of nanoplastics and microplastics on the availability of pharmaceuticals and personal care products in aqueous environment
Researchers found that nanoplastics and microplastics can sorb pharmaceuticals and personal care products in water, with smaller nanoplastics showing 1-2 orders of magnitude stronger sorption than microplastics, potentially reducing the bioavailability of these contaminants in aquatic environments.
Pharmaceuticals and micro(nano)plastics in the environment: Sorption and analytical challenges
This review examines how pharmaceutical residues and micro- and nanoplastics interact in water environments, finding that microplastics can adsorb medications and alter their environmental behavior. Factors like plastic type, surface area, and biological film growth all influence these interactions, but very few studies have been conducted under real-world conditions. The authors highlight persistent analytical challenges and the need for field-based research to understand actual risks.
The combined effects of polystyrene nanoplastics and dissolved organic matter on the environmental bioavailability of carbamazepine
Researchers investigated how polystyrene nanoplastics and dissolved organic matter together affect the bioavailability of the pharmaceutical carbamazepine in water. They found that co-exposure to nanoplastics and fulvic acid increased the bioaccumulation of carbamazepine in water fleas, likely because the organic matter reduced nanoplastic sorption and allowed more of the drug to be absorbed. The study suggests that complex environmental mixtures can amplify the uptake of pharmaceutical pollutants by aquatic organisms.
Microplastics Alter the Distribution and Toxic Potential of Typical Pharmaceuticals in Aqueous Solutions: Mechanisms and Theory Calculations
Researchers studied how polystyrene microplastics interact with common pharmaceutical drugs in water and found that the plastics can absorb these medications, altering their distribution and potentially increasing environmental toxicity. The strength of absorption varied depending on the chemical properties of each drug, with some binding much more readily to microplastics than others. The findings highlight that microplastics may act as carriers for pharmaceutical pollutants, complicating efforts to assess water contamination risks.

Sorption of pharmaceuticals on the surface of microplastics
Researchers tested the ability of four common microplastic types to adsorb nine pharmaceutical compounds frequently found as water pollutants.

Microplastic interactions with co-existing pollutants in water environments: Synergistic or antagonistic roles on their removal through current remediation technologies
This review examines how microplastics interact with other pollutants like heavy metals, pesticides, and pharmaceuticals in water, often making each contaminant harder to remove during treatment. The interactions between microplastics and co-existing pollutants can produce unpredictable combined toxic effects that are worse than either pollutant alone. Understanding these interactions is important because real-world water contamination involves mixtures, not single pollutants, and current treatment methods may not adequately address these combinations.
