ClearFloating photovoltaic systems: photovoltaic cable submersion testing and potential impacts.
This study examines whether submerged photovoltaic cables in floating solar installations degrade over time and release contaminants or plastic particles into aquatic ecosystems. The research addresses a gap in understanding the environmental impacts of floating solar technology as it expands globally.
Experimental data of photovoltaic cable submersion tests
This dataset contains results from submersion tests of photovoltaic (solar panel) cables in freshwater and artificial seawater under realistic conditions. The tests tracked electrical insulation degradation and changes in water chemistry over time. The data is relevant to understanding how plastic-insulated cables used in floating solar installations contribute to microplastic pollution in water bodies.
Experimental data of photovoltaic cable submersion tests
This is a duplicate dataset entry for the photovoltaic cable submersion tests (same as 45414).

It supports assessment of microplastic release from infrastructure-related plastic materials in aquatic environments.
Discussion on the development of offshore floating photovoltaic plants, emphasizing marine environmental protection
Researchers examined the feasibility of building floating solar power plants on the ocean surface and assessed their potential impacts on the marine environment throughout their lifecycle. The study found that while offshore solar energy holds enormous potential, concerns remain about marine ecosystem disturbance including the possible release of microplastics from degrading equipment. The review calls for more research into the environmental interactions of these installations before large-scale deployment.
Aging processes and microplastic release behavior of aquaculture implements
Researchers studied how four types of plastic aquaculture equipment age and release microplastics under simulated marine conditions over 16 weeks. They found that PVC buoys released the most microplastic particles, followed by polypropylene cables, polyethylene nets, and PET buoys, with all materials developing increasingly rough surfaces, cracks, and oxygen-containing chemical groups during aging. The study provides guidance for selecting aquaculture materials that minimize microplastic pollution in marine environments.
Aquatic toxicity of leachates from crystalline silicon photovoltaic components
Researchers evaluated the aquatic toxicity of components from crystalline silicon solar panels by exposing water fleas (Daphnia magna) to leachates from separated module parts. The study found that metals like aluminum and silver from the active cell layer were the primary toxicity concern, while junction boxes and cables showed evidence of hydrocarbon polymer leaching, suggesting that microplastic contamination from solar panel waste should not be overlooked.
The Impact of Chlorinated Water and Sun Exposure on the Durability and Performance of Swimwear Materials
Researchers studied how chlorinated pool water and sun exposure degrade swimwear materials made from blends of polyamide, polyester, and elastane. They found that these aging conditions caused significant deterioration of the fabrics' mechanical properties and durability over time. The findings are relevant to microplastic pollution because degrading swimwear releases synthetic fibers into pool and natural water environments.
From macroplastics to microplastics: Role of water in the fragmentation of polyethylene
Laboratory photodegradation experiments compared how polyethylene plastic films fragment in water versus air under UV light, finding that the aquatic environment significantly influences the physical and chemical breakdown of plastic into microplastics. The study improves understanding of how water immersion changes the photodegradation pathways of floating and submerged plastic debris.

Characterisation of microplastic fibres and their degradation under environmental conditions
This study investigated how UV radiation and mechanical stress degrade common synthetic microfibers including polyester, nylon, and acrylic, which represent the largest fraction of microplastic pollution in aquatic environments. Understanding how fibers degrade helps predict their persistence and how their physical properties change as they age in the environment.
Linking UV aging of polymers and microplastics formation: An assessment employing various characterization techniques
Researchers examined the link between UV aging of plastic polymers and the generation of microplastics in marine environments, using environmental assessment tools to model the process.

Researchers exposed glass fiber reinforced plastic (GFRP) laminates to UV radiation for 1,000 hours both in air and submerged in water, finding that while the outer surface degraded, the deeper layers paradoxically gained strength due to additional chemical cross-linking reactions. These findings are relevant to understanding how plastic composite materials used in marine environments physically break down over time, potentially contributing to microplastic release.
Aging simulation of thin-film plastics in different environments to examine the formation of microplastic
