ClearMechanisms of Sorption of Pharmaceutical and Personal Care Products to Microplastics
This thesis investigated how pharmaceutical and personal care product chemicals sorb onto high-density polyethylene microplastic fragments, and how this affects the combined toxicity to aquatic organisms. Microplastics can carry drug compounds and personal care chemicals from wastewater into aquatic environments, concentrating pollutant exposure for marine organisms.
Microplastic sorption of personal care products in aquatic environments: mechanisms and key factors
This review of existing research shows that tiny plastic particles in water can absorb and carry chemicals from personal care products like sunscreen, soap, and cosmetics. When microplastics pick up these chemicals, they could potentially transport them to new places in the environment and possibly into our food chain. This matters because it suggests microplastics might be spreading personal care chemicals in ways we don't fully understand yet.
Sorption and dissipation of current-use pesticides and personal-care products on high-density polyethylene microplastics in seawater
Researchers characterized how three pesticides and three personal care products sorb onto high-density polyethylene microplastics in seawater. They found that more hydrophobic compounds accumulated more readily on the plastic, and that significant desorption (over 30%) occurred within 24 hours, especially at higher contaminant concentrations. The study confirms that microplastics can act as both carriers and releasers of chemical pollutants in marine environments.
Methods of analysing chemicals associated with microplastics: a review
This review surveys analytical methods used to identify and quantify chemicals associated with marine microplastics, covering extraction techniques, spectroscopic approaches, and the challenges of characterizing the complex mixture of polymer additives and adsorbed contaminants.
Multi-mechanistic adsorption of pharmaceuticals and personal care products on oxidized microplastics: Oxidation processes, mechanisms, and environmental implications
Researchers reviewed how weathering and oxidation change microplastic surfaces, making them better at absorbing pharmaceuticals and personal care product chemicals from water. The modified surfaces attract these contaminants through multiple chemical forces, meaning aged microplastics in the environment act as enhanced carriers for drug and cosmetic pollutants.
Surface functional groups determine adsorption of pharmaceuticals and personal care products on polypropylene microplastics
Researchers found that surface functional groups on aged polypropylene microplastics determined their adsorption capacity for pharmaceuticals and personal care products, with aged plastic showing much higher pollutant uptake than fresh plastic due to weathering-induced surface changes.
Adsorption behavior and interaction mechanism of microplastics with typical hydrophilic pharmaceuticals and personal care products
This study examined how different types of microplastics adsorb hydrophilic pharmaceuticals and personal care products (PPCPs) in aquatic environments, finding that polymer type and surface properties governed the interaction mechanisms. The results indicate that microplastics can act as vectors for these emerging contaminants.
Interactions between microplastics, pharmaceuticals and personal care products: Implications for vector transport
This review examines how microplastics can absorb pharmaceuticals and personal care products (like medications, sunscreen, and antibacterials) onto their surfaces in the environment. Environmental factors like water acidity, salt levels, and organic matter all affect how strongly these chemicals bind to plastic surfaces. When organisms ingest microplastics carrying these absorbed chemicals, the combined exposure could pose greater health risks than either the plastics or chemicals alone.
UV filters and UV stabilisers adsorbed in microplastic debris from beach sand
Researchers detected UV filters and UV stabilizers adsorbed onto microplastic debris collected from beach sand, demonstrating that personal care product contaminants partition onto plastic particles and may be transported and concentrated in marine environments.
The chemical behaviors of microplastics in marine environment: A review
This review summarized interactions between microplastics and organic pollutants and metals in the marine environment, covering sorption behavior across polymer types, the role of degradation in altering sorption capacity, and global monitoring data on pollutant concentrations on marine plastics. The authors conclude that microplastic type, pollutant properties, and environmental conditions all strongly influence chemical accumulation on plastic surfaces.
Insights into emerging organic pollutants extraction from polypropylene, polystyrene, and polyethylene microplastics
Researchers developed and validated an analytical method for extracting and measuring emerging organic pollutants absorbed onto microplastics, simultaneously accounting for particle size, weathering state, and environmental matrix effects for the first time. The method worked well across multiple polymer types and real environmental samples, providing a more reliable tool for assessing the chemical contamination hitchhiking on microplastics in the environment.
Partitioning of chemical contaminants to microplastics: Sorption mechanisms, environmental distribution and effects on toxicity and bioaccumulation
This review critically examines how chemical contaminants like persistent organic pollutants and heavy metals sorb onto microplastic surfaces in the environment. Researchers found that while microplastics can concentrate pollutants at levels far above surrounding water, the actual contribution of microplastics to contaminant transfer into organisms may be less significant than direct exposure from water and food. The study calls for more realistic experimental designs to clarify the true risk.

Researchers extracted microplastics from a specific environmental matrix and characterized their properties — including size, shape, polymer type, and sorption capacity — providing insights into the physical and chemical behavior of environmentally weathered particles.
Sorption and desorption of organic UV filters onto microplastics in single and multi-solute systems
This study examined how organic UV filters (common sunscreen ingredients) sorb onto microplastics in both single-solute and multi-solute systems, finding that competitive sorption occurs when multiple contaminants are present. The results indicate that sunscreen chemicals can hitchhike on microplastics in marine environments, potentially altering their environmental fate and biological effects.
Unravelling the complex interactions between microplastics and PPCPs: The environment and health implications
This review examines how microplastics interact with pharmaceuticals and personal care products (PPCPs), finding that the large hydrophobic surface area of microplastics enhances PPCP adsorption, increasing their persistence, bioavailability, and potential for biomagnification through food webs.
An assessment of the concentration of pharmaceuticals adsorbed on microplastics
This study developed and validated an analytical method to measure pharmaceutical compounds adsorbed onto microplastic particles in marine water samples. Microplastics can concentrate pharmaceuticals from water and carry them through marine food chains, potentially delivering drug compounds to fish and other organisms at elevated concentrations.
Organic pollutants adsorbed on microplastics: Potential indicators for source appointment of microplastics
Researchers investigated whether the organic pollutants stuck to the surface of microplastics could help trace where those microplastics originally came from. They analyzed pollutant profiles on microplastics from different environments and found distinct chemical signatures tied to specific pollution sources. The study suggests that examining adsorbed chemicals on microplastics could serve as a practical tool for identifying and controlling microplastic emissions.
Simultaneous determination of persistent and emerging organic pollutants in microplastics
Researchers developed and validated a new analytical method to simultaneously detect 45 persistent and emerging organic pollutants sorbed onto microplastics. The method was tested on several polymer types including polypropylene and polyethylene, both pristine and weathered, using solvent extraction and gas chromatography-mass spectrometry. The study provides a practical tool for assessing the chemical contamination that microplastics can carry and transport through the environment.

Relative importance of microplastics as a pathway for the transfer of hydrophobic organic chemicals to marine life
Researchers assessed the relative importance of microplastics as a pathway for transferring hydrophobic organic chemicals to marine life. The study suggests that while microplastics can carry high concentrations of contaminants, factors like gut surfactants, pH, and temperature influence desorption rates, and modeling indicates other exposure routes may be more significant in natural environments.
