Health Hazards of Engineering Composite Materials Used in Marine Transportation: Exposure Pathways, Toxicological Risks, and Mitigation Strategies
AI summary Read the abstract
This research review found that the plastic composite materials commonly used in boats and ships can release harmful chemicals and tiny plastic particles that may damage human health. Workers and the public can be exposed to these toxins through breathing, skin contact, or accidentally consuming contaminated water, potentially causing skin reactions, breathing problems, and nerve damage. The study highlights an overlooked health risk from marine plastics and calls for better safety measures to protect both shipyard workers and coastal communities.
Fiber‑reinforced polymer (FRP) composites—primarily GFRP and CFRP—deliver corrosion resistance and weight savings in ships and marine systems, yet their lifecyle health hazards across manufacturing, operation, maintenance, fire events, and end‑of‑life are underexamined. This paper synthesizes occupational and public‑health risks associated with resins (epoxy, vinylester/polyester), hardeners (amines), styrene monomer, fibrous dust (glass and carbon fibers), and smoke/toxic gases from composite fires, alongside microplastics released from coatings and FRP degradation. Drawing on experimental evidence of seawater aging in CFRP/GFRP single‑lap joints (moisture uptake, mechanical changes), it is exposured pathways (inhalation, dermal, ingestion), health outcomes (neurotoxicity, dermatitis/sensitization, respiratory irritation, potential carcinogenicity for certain vitreous fibers), and practical controls (engineering, administrative, PPE) aligned with IMO/SOLAS fire‑safety equivalence principles. It is proposed a risk‑mitigation checklist for shipyards and operators and outline research gaps in dermal uptake biomarkers for epoxy systems and quantitative microplastic health risk from marine sources.

Health Hazards of Engineering Composite Materials Used in Marine Transportation: Exposure Pathways, Toxicological Risks, and Mitigation Strategies
AI summary Read the abstract
This review study examined the health risks from fiber-reinforced plastic materials commonly used in boats and ships, which can release toxic chemicals and tiny plastic particles throughout their lifetime. The researchers found that workers and the public can be exposed to harmful substances through breathing contaminated air, skin contact, or consuming contaminated seafood, potentially causing breathing problems, skin reactions, and nerve damage. The study highlights the need for better safety measures in shipyards and more research on how microplastics from marine sources might affect human health.
Evolution, Prospects, and Predicaments of Polymers in Marine Applications: A Potential Successor to Traditional Materials
AI summary Read the abstract
This review examines the growing use of polymer materials in marine applications such as boat hulls, offshore structures, and underwater equipment, where their light weight and corrosion resistance offer advantages over traditional metals. Researchers also discuss the environmental downsides, including the potential release of microplastics and chemicals as these materials degrade in seawater. The study calls for developing more sustainable polymer formulations that balance performance with reduced environmental impact.
A Review of Microplastics Research in the Shipbuilding and Maritime Transport Industry
AI summary Read the abstract
This review examined microplastic research specifically focused on the shipbuilding and maritime transport industry, an underexplored source of plastic contamination in marine environments. The authors found that ship maintenance, antifouling paint degradation, and fiber rope wear generate significant quantities of microplastics that largely escape current monitoring frameworks.
Composite engineering structures in seawater − Review of durability and environmental performance
AI summary Read the abstract
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.
Microplastics and human health: Exposure pathways, toxicological impacts, and sustainable risk management
AI summary Read the abstract
Tiny plastic particles called microplastics are getting into our bodies through the food we eat (especially seafood), the air we breathe, and even our skin, and once inside, they may cause cell damage, inflammation, and can carry other harmful chemicals along with them. This review paper pulls together what scientists currently know about these risks and points out that we still don't fully understand the long-term health effects of repeated exposure over time. The takeaway: cutting back on plastic use and pushing for better food packaging and policies now could help protect our health before we know the full picture.
