ClearRehashing Our Insight of Seaweeds as a Potential Source of Foods, Nutraceuticals, and Pharmaceuticals
This review summarizes research on seaweed as a source of beneficial compounds including antioxidants, anti-inflammatory agents, and other health-promoting substances. While not directly about microplastics, the research is relevant because seaweeds grow in marine environments increasingly contaminated with microplastics. Understanding the health benefits of seaweed also requires considering the potential risks of microplastic contamination in these marine food sources.
Contribution of seaweed farming to the mitigation of greenhouse gas emissions and microplastics pollution
Researchers reviewed how seaweed farming can help fight two major environmental problems: seaweed absorbs CO2 from the atmosphere without competing for agricultural land, and seaweed-derived polymers can be used to make biodegradable plastics that break down without generating persistent microplastics. Scaling up seaweed-based bioplastics remains limited by production costs, but the potential environmental benefits make further research worthwhile.
Seaweed as a sink for microplastic contamination: Uptake, identifications and food safety implications
This review examines how seaweed, a widely consumed food, absorbs and accumulates microplastics from ocean water. Research shows seaweed can account for up to 45.5% of total dietary microplastic intake in some regions, with particularly high levels in South Asia. The findings are concerning for human health because seaweed is eaten directly and is also increasingly used in health supplements and food additives.
The seaweed Chaetomorpha linum cultivated in an integrated multitrophic aquaculture system: A new tool for microplastic bioremediation?
Researchers tested whether the seaweed Chaetomorpha linum, grown in an aquaculture system, could trap microplastics from surrounding water. The seaweed effectively captured microplastic particles in its tangled filaments, and a simple washing procedure could remove most of the trapped plastics from the harvested biomass. This suggests that growing certain seaweeds could serve as a natural, low-cost way to filter microplastics from marine environments.
Microplastics Content of Seaweeds in the Mariculture Potential Zone at The Southwest of Coastal Bawean Island
Researchers investigated microplastic contamination in seaweeds from Bawean Island, Indonesia, finding that even sheltered coastal waters contained microplastics in red, green, and brown seaweed species collected from mariculture potential zones.
Ecosystem Services Provided by Seaweeds
This review summarizes the many ecosystem services that seaweeds provide, including food production, carbon storage, water filtration, and habitat for marine life. Seaweeds can also help combat pollution by absorbing heavy metals and other contaminants from the water. The review is relevant to microplastics research because healthy seaweed ecosystems may play a role in filtering microplastics from ocean water, and damage to these ecosystems could worsen marine plastic pollution.
Microplastics contamination in seaweed: impacts on human health and mitigation approaches
This review found that microplastics contaminate many types of edible seaweed, with fibers and fragments being the most common forms. Since seaweed is consumed worldwide, these microplastics can enter the human body and potentially cause oxidative damage, cell toxicity, and neurotoxicity. More research is needed to fully understand the health risks of eating microplastic-contaminated seaweed.
Microplastic evidence and removal from the seaweed bioremediator Chaetomorpha linum
Researchers evaluated microplastic presence and removal from the seaweed Chaetomorpha linum collected in the Mar Piccolo of Taranto and transplanted into an integrated multi-trophic aquaculture system, using density-based extraction and spectroscopic identification to characterize trapped particles. The study demonstrated that macroalgae bioremediators can accumulate microplastics from their growth environment, raising considerations for their use in aquaculture-based pollution mitigation.
Exploring the Potential of Algae in the Mitigation of Plastic Pollution in Aquatic Environments
This review examined how algae can help mitigate plastic pollution in aquatic environments, finding that certain algal species can adsorb, degrade, or entrap microplastics, suggesting potential bioremediation applications though large-scale effectiveness remains to be demonstrated.
Algae for plastic biodegradation
This review examines how algae interact with microplastics in marine environments, both as organisms harmed by plastic pollution and as potential agents for plastic biodegradation. Microplastics reduce algal photosynthesis and growth, while algal extracellular polymeric substances can trap and sink microplastic particles. Algae-driven biodegradation represents a promising avenue for reducing the persistence of microplastic contamination in the ocean.
The Prevalence of Microplastics in Farmed Seaweed Kappaphycus Alvarezii in Panguil Bay, Philippines
Researchers investigated microplastic contamination in farmed seaweed from Panguil Bay, Philippines, and confirmed 1,298 microplastic particles across two farming sites. Fibers and filaments were the most common shapes, with rayon and polyester as the dominant polymer types, and washing seaweed before consumption reduced but did not eliminate microplastic content.
Study of microplastic accumulation in halophyte plants and macroalgae: A critical review
This critical review examines how halophyte plants and marine macroalgae accumulate microplastics and nano-plastics from coastal environments, acting as natural traps for marine debris. The authors assess both the ecological implications of plastic accumulation in these organisms and their potential utility as bioindicators or phytoremediation tools for coastal microplastic pollution.
Spatio-temporal features of microplastics pollution in macroalgae growing in an important mariculture area, China
Researchers investigated microplastic contamination in cultivated macroalgae from Haizhou Bay, a major mariculture area in China. They found that seaweed harvested during the culture period contained higher microplastic levels than during non-culture periods, with fibers making up over 90% of particles. The study suggests that aquaculture gear is a significant source of microplastic pollution, releasing an estimated 1,037 tons of plastic into the environment annually.
A review of microplastic impacts on seagrasses, epiphytes, and associated sediment communities
This review synthesizes research on microplastic accumulation in seagrass ecosystems, examining effects on seagrass plants, epiphytic communities, and associated sediment biota. The authors identify seagrass meadows as both sinks for microplastics and potentially sensitive ecosystems where plastic contamination may disrupt complex ecological relationships.
Microplastics in the commercial seaweed nori
Researchers quantified microplastic contamination in commercial nori (edible seaweed) at different stages of processing, finding that microplastics were present in both raw and processed products. The results suggest that nori can accumulate microplastics from its marine growing environment and retain them through processing into consumer products.

This review examined the interactions between micro- and nanoplastics and microalgae, covering how microalgae are affected by plastic particles and how they can in turn be used to remove plastics from aquatic environments. The authors identify microalgae-based systems as promising tools for combined plastic removal and biomass production.
Biomonitoring of microplastics, anthropogenic microfibres and glass retroreflective beads by marine macroalgae
Researchers explored the potential of marine macroalgae as biomonitors for microplastics, anthropogenic microfibers, and glass retroreflective beads in coastal environments. The study suggests that seaweed species could offer a more standardized and reliable method for tracking microscopic debris compared to conventional water and sediment sampling approaches.
