ClearA baseline studies programme for sustainable and resilient seaweed cultivation in Faroese fjords
Researchers developed a baseline environmental studies programme for seaweed cultivation in Faroese fjords, scoping potential impacts on the marine environment and recommending a monitoring programme to support sustainable and resilient aquaculture development in the Faroe Islands.
Food safety in the seaweed food supply chain : Inventory of production, consumption and chemical and physical hazards
This Dutch food safety report inventories the chemical and physical hazards — including microplastics — present in seaweed cultivated for human consumption. As the seaweed food market grows, understanding contamination risks including plastic particles is important for protecting consumer health.
Learning to discuss safety within the European seaweed aquaculture sector
This paper is not about microplastics. It introduces a generic safety assessment protocol for the European seaweed aquaculture sector, covering food safety, environmental safety, and occupational health. While seaweed farming occurs in marine environments where microplastics are present, the study focuses on developing safety frameworks for the aquaculture industry rather than addressing microplastic contamination.
Exploring Seaweed Cultivation in the Marine Environment and Its Interaction with Microplastic
This review examines interactions between seaweed cultivation in marine environments and microplastic pollution, exploring how seaweed can both accumulate microplastics and potentially be used in bioremediation strategies to reduce plastic contamination in coastal waters.
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.
A review of remote sensing in coastal aquaculture: data, geographic hotspots, methods, and challenges
A review of remote sensing applications in coastal aquaculture examined available data sources, geographic coverage, and analytical methods for monitoring aquaculture zones. This is relevant to microplastic research because aquaculture operations are both exposed to and potential sources of microplastic contamination in coastal waters.
Microplastic contaminations in edible seaweed Caulerpa racemosa across Indonesian tropical seawaters related to land uses: Implication on human health
This study measured microplastic contamination in the edible seaweed Caulerpa racemosa harvested from both inland and island environments in Indonesia, finding higher contamination in inland coastal areas with greater urbanization. The results suggest land use and proximity to human activity are key drivers of MP contamination in edible seaweeds.
A comparative environmental life cycle assessment of hatchery, cultivation, and preservation of the kelpSaccharina latissima
Researchers conducted a comparative environmental life cycle assessment of hatchery, cultivation, and preservation stages for the brown seaweed Saccharina latissima at a pilot facility in Sweden, accounting for nutrient bioremediation and carbon capture benefits. The study evaluated the environmental sustainability profile of seaweed cultivation as part of potential contributions to the circular bioeconomy.
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.
The distribution and ecological effects of microplastics in an estuarine ecosystem
Researchers surveyed 22 intertidal sites and found that microplastic abundance, size, and diversity correlated with benthic microalgal communities and sediment biostabilization properties in an estuarine ecosystem.
Development of Optimal Digesting Conditions for Microplastic Analysis in Dried Seaweed Gracilaria fisheri
Researchers compared enzymatic, oxidative, and combined digestion methods for extracting microplastics from dried seaweed, optimizing conditions for reliable identification and quantification. The combined method produced the best plastic recovery with the least damage to particles. Validated extraction methods for edible seaweeds are important because seaweed is increasingly consumed as food and could be a pathway for microplastic ingestion.
A global spatial analysis reveals where marine aquaculture can benefit nature and people
A global spatial analysis identified marine ecoregions with the greatest potential for shellfish and seaweed aquaculture to simultaneously restore coastal ecosystems and provide food benefits to humanity, with highest opportunity regions in Oceania, North America, and parts of Asia. The study proposes a strategic framework for expanding sustainable marine aquaculture in alignment with ecosystem recovery goals.
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.
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.
Coastal ecosystem inventory with characterization and identification of plastic contamination and additives from aquaculture materials
Researchers conducted a pilot study of an Atlantic French coastal area used for oyster aquaculture and found that 70% of beached plastics originated from aquaculture materials, while sediment samples contained microplastics carrying plastic-associated chemical additives, documenting a distinct aquaculture-driven contamination signature.
A review of remote sensing in coastal aquaculture: data, geographic hotspots, methods, and challenges
This review examines remote sensing applications in coastal aquaculture, synthesising data sources, geographic hotspots, and methodological advances that allow satellite and aerial imagery to monitor aquaculture facility extent, water quality, and environmental impacts including plastic debris from aquaculture infrastructure.
Testing indicators for biological impacts of microplastics .
Researchers reviewed indicators that could be used to detect biological harm from microplastics in marine organisms, noting that the EU has not yet achieved healthy seas partly due to marine litter. The study examines how different marine organisms—from filter feeders to planktivores—are exposed to microplastics and what measures of biological impact would be most informative.
The empirical evidence for the social-ecological impacts of seaweed farming
This systematic review assessed empirical evidence for social and ecological impacts of seaweed farming globally, finding that while benefits like improved water quality and coastal livelihoods are well-documented, many other claimed benefits lack strong empirical support.
Assessing the Impact of Microplastic Pollution on Coastal Ecosystems: a Multidimensional Environmental Approach
This review presents a comprehensive multidimensional analysis of microplastic pollution in coastal ecosystems, examining how microplastics alter sediment dynamics, disrupt marine food webs, and interact synergistically with heavy metals and persistent organic pollutants to create a complex environmental crisis requiring integrative management solutions.
Progress on microplastics pollution and its ecological effects in the coastal environment
This review systematically summarizes a decade of research on microplastic pollution and its ecological effects in coastal environments worldwide, identifying persistent technical challenges in sampling standardization, particle identification, and ecological impact assessment. Researchers highlight the need for unified methodologies to better understand the sources, fate, and biological consequences of coastal microplastic contamination.
