Aggregation of original and UV-aged polypropylene microplastics under the intervention of glomalin-related soil protein

AI summary Read the abstract

Researchers investigated how glomalin-related soil protein (GRSP) interacts with original and UV-aged polypropylene microplastics, finding that GRSP binds to both particle types and promotes aggregation. Aged particles showed 24.5% higher GRSP adsorption than virgin ones, with aggregation altering particle surface properties and potentially affecting microplastic migration in soil.

Aggregation of positively charged polystyrene nanoplastics in soil–root systems

AI summary Read the abstract

Researchers showed that positively charged polystyrene nanoplastics aggregate in the presence of plant root exudates and soil leachate while negatively charged nanoplastics remain stable and mobile, driven by organic acid adsorption onto nanoparticle surfaces. Understanding nanoplastic charge-dependent behavior in soil-root systems is crucial for assessing how nanoplastics are taken up by crops and may enter the human food supply.

Microplastics and Their Effects on Soil Function as a Life-Supporting System

AI summary Read the abstract

Microplastics alter essential soil functions by changing soil structure, water retention, microbial communities, and nutrient cycling in ways that threaten the life-supporting capacity of agricultural and natural soils. As terrestrial microplastic contamination continues to grow — exceeding ocean concentrations in many regions — the long-term health of soil ecosystems and food production is at risk.

The impact of large microplastics on the physical behavior of soils: implications to marine sediments

AI summary Read the abstract

Researchers tested how PVC microplastic chips alter the physical properties of marine sediment analogues, finding that as little as 1% plastic content by volume irreversibly changed compressibility, strength, stiffness, and hydraulic conductivity — with coarser sediments showing greater sensitivity — raising concerns about long-term seafloor stability as plastic accumulation continues.

Aggregation and Aggregate Strength of Microscale Plastic Particles in the Presence of Natural Organic Matter: Effects of Ionic Valence

AI summary Read the abstract

Calcium ions promote stronger aggregation of polyethylene microplastic particles in the presence of natural organic matter through divalent bridging, producing more cohesive aggregates than monovalent potassium ions. Understanding how microplastics aggregate under different water chemistry conditions is important for predicting their transport, sedimentation, and bioavailability in natural aquatic environments.
