Presentation of preliminary results of an experiment on the sorption of metals on the surface of microplastic particles in the natural waters of Karelia
AI summary Read the abstract
This preliminary Russian study tested how metal ions sorb onto microplastic particle surfaces in natural water samples from the Karelian region. Researchers found that metal sorption varied by element, microplastic size, and water organic matter content. The results suggest that microplastics in natural freshwater can accumulate metal pollutants, though the extent depends on local water chemistry.
The paper presents preliminary results of a model experiment on the sorption of metals on the surface of microplastic particles (MP) in the conditions of natural waters of Karelia. It was found that the interaction of the studied metals with MP particles is different and largely depends on the concentration of elements and the content of organic matter in the studied aqueous samples, the size of the microplastic particles. The results showed that the sorption of metals on the surface of the particles increases with time, while iron will be one of the first to be sorbed, since its content is an order or two higher than all other metals.

Assessment of the sorption capacity of PET microparticles in natural water with respect to metals
AI summary Read the abstract
Researchers measured the capacity of PET microplastic particles to sorb metals from natural water under different chemical conditions, finding that pH and dissolved organic matter strongly influenced uptake. The results suggest that PET microplastics in rivers and lakes can act as secondary carriers of trace metals, potentially altering their bioavailability and toxicity.
Features of Heavy Metals Sorption by Microplastics in Environmentally Relevant Conditions
AI summary Read the abstract
Experiments using aged PET microplastics in natural lake water showed that the particles sorb heavy metals (cobalt, nickel, copper, cadmium, lead) in environmentally relevant concentrations, but the sorption isotherms differed from those measured in synthetic laboratory solutions. This matters because microplastics acting as vectors for heavy metals in real freshwater conditions could increase metal bioavailability and toxicity to aquatic life and potentially to humans who drink the water.

Microplastics meet micropollutants in a central european river stream: Adsorption of pollutants to microplastics under environmentally relevant conditions
AI summary Read the abstract
Researchers investigated how microplastics adsorb organic micropollutants in a Central European river under real-world conditions. They found that aged microplastics showed higher adsorption capacity for contaminants compared to pristine ones, and that the type of plastic material influenced which pollutants were absorbed. The findings suggest that microplastics in rivers can act as carriers for harmful chemicals, potentially spreading contamination through aquatic ecosystems.
