ClearA comparative study of microplastics under the influence of soil-typical eco-coronas through laboratory and field incubation experiments
Researchers compared the formation and properties of soil-typical eco-coronas on microplastics through both laboratory incubation and real-world field experiments, examining how natural organic matter coatings of proteins, carbohydrates, and humic acids alter microplastic surface hydrophobicity and transport behaviour. The study found that eco-corona composition significantly influences how microplastics move through terrestrial environments and interact with soil organisms.
Eco-corona formation and associated ecotoxicological impacts of nanoplastics in the environment
This review examines how nanoplastics interact with natural organic matter in the environment to form an 'eco-corona,' a coating of biomolecules on the particle surface that changes their behavior and toxicity. Researchers found that eco-corona formation alters nanoplastic stability, transport, and biological interactions in ways that can either increase or decrease their harmful effects on organisms. The study highlights the importance of considering these surface transformations when assessing the real-world environmental risks of nanoplastic pollution.
A comparative study of microplastics under the influence of soil-typical eco-coronas through laboratory and field incubation experiments

Soil Metabolome Impacts the Formation of the Eco-corona and Adsorption Processes on Microplastic Surfaces
This study found that natural molecules in soil form a coating (called an eco-corona) on microplastic surfaces, which changes how chemicals stick to them. The type and amount of coating depends on the soil's chemical makeup, meaning microplastics behave differently in different soils. This matters because it affects what pollutants microplastics can carry into the food chain and water supply.
The development of eco-coronas on agricultural nanomaterials reduces their harmful impact: a review
This review examines how 'eco-coronas' — layers of soil biomolecules that form on agricultural nanomaterials including microplastics — affect the toxicity of those particles to crops and soil organisms. The eco-corona can reduce or modify the harmful impacts of nanomaterials by changing their surface chemistry. Understanding how eco-coronas develop on microplastics in soil helps predict their real-world environmental behavior, which may differ from laboratory studies using clean particles.

Eco-Corona Formation Enhances Cotransport of Nanoplastics and Organic Contaminants in Porous Media
Researchers demonstrated that eco-corona formation, the coating of nanoplastics by environmental macromolecules, significantly enhances the co-transport of nanoplastics and organic contaminants through porous media like soil. The study found that even small amounts of eco-corona on polystyrene nanoplastics promoted the transport of the pollutant 4-nonylphenol, suggesting this natural coating process may accelerate the spread of both nanoplastics and associated contaminants through the environment.

This review examines how nanoplastics in aquatic environments interact with natural biomolecules to form an eco-corona coating that fundamentally changes their behavior and ecological impact. Researchers found that this biological coating alters the surface chemistry, transport, and toxicity of nanoplastic particles in ways that depend on environmental conditions. The study highlights that understanding eco-corona formation is essential for accurately assessing the real-world risks of nanoplastic pollution.
Repulsive interactions of eco-corona covered microplastic particles quantitatively follow modelling of polymer brushes
Researchers studied how the 'eco-corona' — a layer of natural organic molecules that coats microplastics in the environment — affects how plastic particles interact with each other and with surfaces. The eco-corona increased repulsion between particles, following patterns predicted by polymer brush physics models. Understanding the eco-corona is important for predicting how microplastics behave and accumulate in real-world environments.
Toxicity of micro/nanoplastics in the environment: Roles of plastisphere and eco-corona
This review examines how microplastics and nanoplastics gain biological coatings in the environment: larger microplastics develop a "plastisphere" of microorganisms on their surface, while smaller nanoplastics get wrapped in proteins and organic matter forming an "eco-corona." Both coatings change how toxic the particles are to living organisms and humans. The review highlights that studying plastic particles without these coatings, as most lab experiments do, may underestimate or mischaracterize their real-world health risks.
Soil Solution Promotes Nanoplastic Aggregation via Eco-corona Formation and Hetero-aggregation
Scientists found that tiny plastic particles in soil clump together into bigger chunks when they interact with natural soil chemicals and microbes. This clumping could affect how these plastic particles move through soil and potentially into our food and water supply. Understanding how plastic pollution behaves in soil helps us better predict human exposure to these particles.
Coronas of micro/nano plastics: a key determinant in their risk assessments
This review examines how micro- and nanoplastics develop surface coatings called coronas when they interact with biological and environmental substances.

The study suggests that understanding these surface coatings is essential for accurately assessing the real-world risks of plastic particle exposure.
The interaction of micro/nano plastics and the environment: Effects of ecological corona on the toxicity to aquatic organisms.
This review examines how the ecological corona — the layer of organic matter, proteins, and microbes that form on micro- and nanoplastic surfaces in water — affects their toxicity to aquatic organisms. The ecological corona can either increase or decrease toxicity depending on its composition, making real-world plastic hazard assessment more complex than laboratory tests with clean particles suggest.

A Review of Eco-Corona Formation on Micro/Nanoplastics and Its Effects on Stability, Bioavailability, and Toxicity
When microplastics and nanoplastics enter water, natural substances like humic acid coat their surfaces, forming what scientists call an "eco-corona." This coating changes how the plastic particles behave, including how they clump together and how easily organisms absorb them. Importantly, the eco-corona can actually reduce some of the toxic effects of these plastic particles, such as growth problems and oxidative stress.
Environmental dimensions of the protein corona
Researchers reviewed how nanomaterials entering natural environments acquire an "eco-corona" — a coating of proteins and other biomolecules that alters how organisms recognize and interact with the particles — and called for targeted research into how this coating changes during food chain transfer and affects ecotoxicity.
Aggregation of Nanoplastics via Eco-corona Formation and Hetero-Aggregation in Soil Solution
This laboratory study found that soil solution dramatically accelerates the clumping (aggregation) of nanoplastics made from both conventional polyethylene and the biodegradable plastic PBAT, primarily due to the formation of an 'eco-corona' of organic matter and colloids on particle surfaces. Increased aggregation reduces nanoplastic mobility in soil but may also concentrate associated pollutants. Understanding how nanoplastics behave in real soil conditions is essential for predicting their environmental fate and potential uptake by soil organisms and plant roots.
