ClearThe adverse health effects of increasing microplastic pollution on aquatic mammals
Researchers reviewed the current evidence on microplastic contamination in aquatic ecosystems and its adverse health effects on aquatic mammals, which are particularly vulnerable as top predators. The study highlights that microplastics accumulate through the food chain and may cause physical harm, chemical toxicity, and serve as carriers for other pollutants, posing serious concerns for marine mammal populations.
How plastic debris and associated chemicals impact the marine food web: A review.
This review examined how plastic debris and associated chemicals disrupt marine food webs at all trophic levels, from physical entanglement and false satiation in megafauna to microplastic ingestion and chemical transfer through trophic magnification, concluding that plastic contamination poses systemic threats to marine ecosystem function.
Impacts of microplastics on immunity
This review examines the growing evidence that microplastics and nanoplastics can affect the immune system, covering studies in marine organisms, mammals, and human cell lines. Researchers found that these particles can trigger inflammation, alter immune cell function, and disrupt immune signaling pathways. The study underscores the need for more immunological research to fully understand how plastic particle exposure may compromise immune health in humans.
The Impact of Microplastic Bioaccumulation on Marine Ecosystems
This review examined the bioaccumulation of microplastics in marine ecosystems, tracing MP uptake from zooplankton to fish to marine mammals and discussing the ecological disruptions caused by plastic accumulation across food webs. It called for integrated solutions addressing MP pollution at both the source and ecosystem levels.
Microplastic pollution as a grand challenge in marine research: A closer look at their adverse impacts on the immune and reproductive systems
This review summarizes the effects of microplastic pollution on the immune and reproductive systems of marine species, covering studies on invertebrates and vertebrates exposed to various plastic types. Researchers found that immune responses varied by species, with changes in defense mechanisms observed in fish and cellular damage in mollusk immune cells. The study highlights that while reproductive and immune impacts of microplastics are increasingly documented, significant knowledge gaps remain, particularly for vertebrate marine species.
Micro- and nanoplastics as immunomodulatory vectors: synergistic interactions with pollutants and pathogens across aquatic food webs
This review examines how micro- and nanoplastics act as immunomodulatory vectors by adsorbing persistent organic pollutants, heavy metals, and pathogenic microorganisms onto their surfaces, transporting these hazardous agents through aquatic food webs and enhancing combined immune disruption in exposed organisms.
Ecological impact of microplastic pollution on marine food webs
This review examines how microplastic pollution disrupts marine food webs, tracing the transfer of plastic particles and associated chemicals from plankton through fish to top predators and analyzing the ecological consequences for marine biodiversity and ecosystem functioning.
Micro Plastics in The Marine Environment: A Review of Their Effects on Marine Organisms and Ecosystems
This review examines the effects of microplastics on marine organisms and ecosystems, summarizing evidence for MP ingestion across trophic levels, physical and chemical harm to marine life, and the pathways through which marine MP pollution threatens biodiversity and fisheries.
Ecotoxicological Impacts of Micro and Nanoplastics on Marine Fauna
This review examines the ecotoxicological impacts of micro- and nanoplastics on marine fauna, detailing how these particles enter food chains through ingestion, accumulate across trophic levels, and cause physical and chemical harm including oxidative stress, inflammation, reproductive disruption, and mortality. The authors highlight the compounding threat when plastics act as vectors for adsorbed pollutants.
Los mamíferos marinos y la contaminación por plásticos
This review examines the growing evidence of plastic pollution impacts on marine mammals, describing how entanglement, ingestion, and chemical exposure from plastic debris affect some of the most exposed megafauna groups in the world's oceans.
Marine litter: trends and impacts in marine fauna
This review synthesizes evidence on marine litter sources, distribution, and ecological impacts, with particular focus on microplastics as a pervasive contaminant across all marine habitats. It finds that microplastics threaten marine life through ingestion, entanglement, and chemical transport, with impacts spanning trophic levels from plankton to large marine mammals.
Physiological Effects of Microplastic on Marine Organisms
This review examines the physiological effects of microplastics on marine organisms, covering how plastic particles—from fragmentation of larger debris or manufactured microbeads—are ingested, accumulate in tissues, and disrupt metabolic and immune functions. It concludes that the ever-increasing concentration of MPs in marine environments represents a growing threat to marine biodiversity and ultimately to human health through the food chain.
Cellular and Systemic Effects of Micro- and Nanoplastics in Mammals—What We Know So Far
This review summarized known cellular and systemic effects of micro- and nanoplastics in mammals, finding that while ingestion is common, knowledge of health impacts remains limited, with oxidative stress and inflammation as the most reported biological responses.
Unveiling the effects of microplastics pollution on marine fauna
This review examines how microplastic pollution harms marine animals at every level of the food chain, from tiny plankton to large predators. Through ingestion, entanglement, and building up in tissues over time, microplastics disrupt feeding, reproduction, and growth in marine life, which also raises concerns about human exposure through seafood consumption.
Sorption, uptake, trophic transfer and immunotoxicity of microplastics and nanoplastics in the aquatic environment
This review examines how microplastics and nanoplastics are sorbed, taken up by organisms, transferred through food webs, and how they affect immune function in aquatic species. Researchers synthesize evidence showing these particles can accumulate across trophic levels and trigger immunotoxic effects, with implications for both wildlife and human health.
Immune Disruption and Disease Development by Microplastic Exposure
This review synthesized growing evidence that microplastic and nanoplastic exposure disrupts the human immune system, covering how particles ingested, inhaled, or absorbed through skin can trigger inflammation, impair immune cell function, and potentially contribute to autoimmune and allergic conditions.
Microplastic in tissue of marine organisms
This review summarizes microplastic detection across various marine organism tissues, cataloging accumulation in fish, invertebrates, and marine mammals and highlighting that ingestion and trophic transfer are widespread across marine food webs.
Effect of micro- and nanoplastics as food contaminants on the immune system
This review synthesized research on how microplastic and nanoplastic exposure affects immune system function, finding evidence across multiple studies that these particles can modulate immune responses and trigger inflammatory pathways in exposed organisms. The authors highlight immune disruption as an emerging health concern from micro- and nanoplastic contamination.
Impacts of microplastic accumulation in aquatic environment: Physiological, eco-toxicological, immunological, and neurotoxic effects
This review summarizes how microplastics build up in fish and other aquatic life, causing damage to their immune systems, nervous systems, and overall health. When fish eat microplastics, the particles move up the food chain and can eventually reach humans through seafood consumption. The authors also discuss strategies for removing microplastics from water and reducing plastic pollution.
A comprehensive review of the impact of microplastics on aquatic organisms: From ingestion to ecological consequences
This comprehensive review assessed the impacts of microplastics on diverse aquatic organisms—including fish, marine mammals, mollusks, crustaceans, and microorganisms—from ingestion through ecological-level consequences. The authors found that microplastics cause physical injury, oxidative stress, endocrine disruption, and behavioral changes across taxa, with downstream effects on food web structure and ecosystem function.
