This review examines the balance between marine ecological health and the development of nutraceuticals and functional foods from ocean species. The study discusses how pollution including microplastics threatens marine ecosystems while also covering the bioactive compounds from marine organisms that show potential antioxidant, cardio-protective, and neuroprotective properties.
Chitosan as a sustainable alternative for fresh food packaging: Structural insights, modification strategies, and innovations for commercial viability
Researchers reviewed how chitosan — a natural biopolymer derived from crustacean shells — can serve as a biodegradable alternative to single-use plastic food packaging, detailing chemical modification strategies, nanocomposite reinforcement approaches, and recent advances in antimicrobial and antioxidant performance that improve its commercial viability.
Valorization of Seafood Processing Byproducts for Sustainable Fertilization: Opportunities and Food Safety Considerations in Agriculture 4.0
This review explores the potential of using seafood processing waste — fish offal, shellfish shells, and aquaculture effluents — as natural fertilizers in modern farming systems. While these byproducts are rich in nutrients and could reduce reliance on synthetic fertilizers, the paper also flags important food safety concerns, including the presence of microplastics in marine-derived materials that could be introduced to agricultural soils. The authors conclude that seafood-derived fertilizers are promising for circular agriculture, but careful screening for contaminants including microplastics is essential before widespread adoption.
Persian Gulf Bivalves: Bioactive Pharmaceutical Compounds and Biomedical Applications
This review covers the bioactive compounds found in bivalves from the Persian Gulf and their potential pharmaceutical and medical applications. Bivalves are relevant to microplastic research because they filter large volumes of water and accumulate microplastics and associated chemicals in their tissues. This paper focuses on medicinal compounds rather than contamination.
Compounds of Marine Origin with Possible Applications as Healing Agents
This paper is not relevant to microplastics research; it reviews bioactive compounds from marine organisms and their potential applications in wound healing and cosmetic formulations, with no focus on plastic contamination.
The Eco-Immunological Relevance of the Anti-Oxidant Response in Invasive Molluscs
Not relevant to microplastics — this review examines how antioxidant defence mechanisms in invasive mollusc species help them survive environmental stress and support immune function, with no focus on microplastic exposure.
Highly Efficient, Recyclable Microplastic Adsorption Enabled by Chitin Hydrogen Bond Network Rearrangement
Scientists developed a foam made from chitin, a natural material found in seafood shells, that can absorb over 400 milligrams of nano-sized microplastics per gram of material, even in saltwater. This recyclable, sustainable approach could help clean microplastics from ocean water, and the recovered plastic can be converted into useful products.
Neuroprotective compounds from marine invertebrates
Researchers reviewed biologically active compounds found in marine invertebrates like sponges, sea cucumbers, and coral, many of which show potential for treating neuroinflammatory diseases such as Alzheimer's and Parkinson's by targeting key proteins involved in brain inflammation and cell death. While promising, the review notes that challenges around sustainable sourcing and the need for more clinical trials remain significant hurdles before these marine compounds reach patients.
Microplastic prevalence, diversity and characteristics in commercially important edible bivalves and gastropods in relation to environmental matrices
Researchers assessed microplastic abundance and characteristics in the tissues of commercially important bivalves and gastropods from the southwest coast of India, finding MPs across all five species examined and raising concerns about seafood safety.
Effectiveness of Green Mussel Shells as a Natural Coagulant for Domestic Wastewater Treatment
Researchers found that chitosan extracted from green mussel shells acted as an effective natural coagulant for domestic wastewater, achieving up to 100% reduction in total suspended solids and 73% reduction in turbidity at an optimal dose of 0.4 g/L, offering a biodegradable alternative to chemical coagulants.
Marine Biopolymers: Applications in Food Packaging
This review examined the use of marine-derived biopolymers such as proteins and polysaccharides for food packaging applications. The study suggests that these biodegradable materials could significantly reduce reliance on conventional plastic packaging, offering environmental and economic benefits while improving the shelf life of packaged foods.
Extraction and identification of microplastics from mussels: Method development and preliminary results
Scientists developed and validated a method for extracting and identifying microplastics from mussel tissue, then applied it to measure contamination in commercially harvested mussels. The method produced reliable, reproducible results, providing a practical tool for monitoring microplastic levels in one of the world's most widely consumed shellfish.
Biopolymer from Marine Waste Biomass and Its Applications- A Review

Biomineralization biomarkers to assess microplastics toxic effects in the freshwater snail Pomacea canaliculata
Researchers investigated how polyethylene microplastic exposure at environmentally relevant concentrations affects biomineralization processes in the freshwater snail Pomacea canaliculata. The study found that microplastics altered calcium transport enzyme activity and hemolymph calcium levels within 24 hours, and interestingly, exposed snails showed an increased capacity to regenerate their shells. These findings provide novel evidence that microplastics can stimulate biomineralization responses in mollusks, potentially as a stress-related defense mechanism.
Rehashing 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.
Eco-friendly and safe alternatives for the valorization of shrimp farming waste

Bioactive Compound and Functional Properties of Sea Cucumbers as Nutraceutical Products
This review examines the nutritional and bioactive compounds found in sea cucumbers, including proteins, collagen, and omega-3 fatty acids that have anti-inflammatory and antioxidant properties. While not directly about microplastics, sea cucumbers are bottom-dwelling filter feeders that are highly exposed to microplastic contamination in ocean sediments. As sea cucumbers are increasingly used in supplements and food products, their potential to accumulate microplastics raises concerns about another route of human exposure.

Towards Risk Assessments of Microplastics in Bivalve Mollusks Globally
Researchers compiled data from 22 countries to assess the risk of microplastic contamination in bivalve mollusks such as mussels and oysters. While most countries showed relatively low pollution levels, the chemical composition of the microplastics found in bivalves varied widely, with some polymers posing greater health concerns than others. The study estimates that regular consumption of contaminated bivalves could represent a meaningful pathway for human microplastic exposure.
