ClearBiodeterioration and Chemical Corrosion of Concrete in the Marine Environment: Too Complex for Prediction
This review examines the chemical degradation and biodeterioration of concrete in marine environments, covering reactions with chloride, sulfate, and magnesium ions as well as acid-producing microbial activity. The review highlights the difficulty of predicting degradation rates due to the complex interplay of biological and chemical factors.
The effect of time and surface type on the composition of biofilm communities on concrete exposed to seawater
Researchers examined how time and concrete surface type influence biofilm community composition on marine concrete structures, finding that both factors shape microbial succession in ways relevant to understanding concrete biodegradation in seawater.
Global Decarbonization Enabled by a Novel Strategy of Biomineralization for Concrete Corrosion Inhibition
Despite its title referencing concrete corrosion and coastal infrastructure, this paper studies a biomineralization-based method for protecting marine concrete structures from corrosion in order to extend their lifespan and reduce greenhouse gas emissions — not microplastic pollution. It examines life-cycle carbon accounting for this construction technique and is not relevant to microplastics or human health.
Composite engineering structures in seawater − Review of durability and environmental performance
This review assesses the long-term durability and environmental performance of fiber-reinforced composite structures used in seawater for shoreline protection. Researchers found that while composites offer advantages over steel and concrete for coastal infrastructure, they can release microplastics and other pollutants as they degrade over time. The study emphasizes the need for better understanding of how these materials age in marine environments to avoid trading one environmental problem for another.
Multiaxial Fatigue Life Assessment of Integral Concrete Bridge with a Real-Scale and Complicated Geometry Due to the Simultaneous Effects of Temperature Variations and Sea Waves Clash
This engineering study modeled fatigue stress in a real-scale concrete bridge with steel piles under combined loading from temperature changes and sea wave impacts, identifying steel piles as the most vulnerable structural component. While focused on structural engineering, the study demonstrates analytical approaches to predicting wear and degradation of materials in marine environments — relevant to understanding how structural materials release microplastic-like particles.
Microbially influenced corrosion and rust tubercle formation on sheet piles in freshwater systems
This paper is not relevant to microplastics; it investigates the microbial communities and electrochemical processes responsible for corrosion and rust formation on steel sheet piles in a German freshwater river.
Simulated experimental investigation of microplastic weathering in marine environment
Researchers simulated microplastic weathering under marine conditions, finding that exposure to UV light, saltwater, and mechanical abrasion progressively degraded plastic surfaces, increased surface roughness, and enhanced the adsorption capacity of contaminants onto microplastic particles.
Characterization of three plastic forms: Plasticoncrete, plastimetal and plastisessiles
Researchers identified and characterized three previously undescribed forms of plastic that have fused with other materials: plasticoncrete (plastic fibers embedded in concrete), plastimetal (plastic rusted with metal), and plastisessiles (plastic fibers anchored by oysters and worms). These hybrid plastic forms sink and stay put, showing that plastic can become permanently locked into coastal environments through both industrial and biological processes.
Weathering Processand Characteristics of Microplasticsin Coastal Wetlands: A 24-Month In Situ Study
Researchers conducted a 24-month study of microplastic weathering in coastal wetlands, characterizing how wetland-specific conditions including UV exposure, salinity, and biological activity alter plastic surface chemistry, fragmentation, and biofilm colonization over time.
Metal leaching from plastics in the marine environment: An ignored role of biofilm.
Researchers investigated how biofilms on marine plastics influence metal leaching, finding that microbial colonization significantly alters the release rates of metal additives from common polymers, representing a previously underappreciated pathway for heavy metal transfer from plastic debris into marine ecosystems.
Protective Effects of Small Molecular Inhibitors on Steel Corrosion: The Generation of a Multi-Electric Layer on Passivation Films
This paper is not about microplastics; it uses molecular dynamics simulation to study how corrosion inhibitor molecules protect steel reinforcements in concrete from chloride ion attack.
Reef‐building corals act as long‐term sink for microplastic
Coral reef structures were shown to act as long-term sinks for microplastics, with microplastics accumulating in reef framework interstices and sediments at higher concentrations than surrounding seawater, potentially contributing to the resolution of the missing plastic problem in ocean budgets.
Unveiling the duality of cement and concrete addressing microplastic pollution: a review
This review explores the dual role of cement and concrete in microplastic pollution -- they can both contribute to and potentially help filter out microplastics from the environment. The research suggests that specially designed porous concrete could be used in water filtration systems to capture microplastics before they reach drinking water supplies.
Eco-engineering: a concrete solution to increasing biodiversity and monitoring microplastics.
Researchers developed eco-engineered artificial coastal structures with surface features—tide pools, grooves, and pits—designed to increase biodiversity while incorporating microplastic monitoring capabilities. Field deployment showed eco-engineered surfaces supported higher species richness than conventional concrete and could serve as platforms for passive plastic particle collection.
The Influence of Ocean Acidification on The Surface Alteration of Microplastics
Researchers exposed virgin microplastics to normal seawater (pH 8.0) and acidified seawater (pH 7.7) for 10 days, using field emission scanning electron microscopy to show that ocean acidification accelerates surface aging and physical damage to microplastic particles, suggesting that increasing ocean acidity may enhance chemical leaching from plastics.
Comprehensive assessment of photo-oxidative degradation and biofilm colonization on microplastic pellets in simulated marine environment
Researchers exposed polyethylene, polypropylene, and nylon-6 microplastics to artificial UV aging and chemical oxidation in seawater to study photo-oxidative degradation and subsequent biofilm colonization. Aging altered surface chemistry and enabled biofilm formation, with degradation rates and biofilm composition varying by polymer type.
A Step towards Sustainable Concrete with Substitution of Plastic Waste in Concrete: Overview on Mechanical, Durability and Microstructure Analysis
This review evaluates the use of plastic waste as a substitute material in concrete, analyzing its effects on mechanical strength, durability, and microstructure to assess its viability as a sustainable construction approach.
Reducing Uncertainty and Confronting Ignorance about the Possible Impacts of Weathering Plastic in the Marine Environment
This paper argues that weathering of plastic in the ocean is poorly understood but critically important, as it generates microplastics, nanoplastics, and releases chemical additives over time. Researchers highlight that biofilms growing on ocean plastic affect how it weathers, sinks, and interacts with marine life, yet this process has been underinvestigated. The study calls for laboratory experiments, field monitoring, and modeling to reduce uncertainty about the hazards of aging plastic debris in marine environments.
Utilization of plastic waste as replacement of natural aggregates in sustainable concrete: effects on mechanical and durability properties
Researchers tested concrete made with recycled polyethylene and PET plastic aggregates substituted for natural sand and gravel, finding that while plastic additions reduced compressive strength and increased water permeability, they improved impact resistance and chloride resistance, with PET concrete showing no microplastic leaching.
