ClearEnvironmental Pollutants and Oxidative Stress in Terrestrial and Aquatic Organisms: Examination of the Total Picture and Implications for Human Health
This comprehensive review examines how various environmental pollutants, including microplastics, toxic metals, and pesticides, induce oxidative stress in both terrestrial and aquatic organisms. The study highlights the interconnected pathways through which pollution-driven oxidative damage in wildlife may carry implications for understanding broader environmental health risks.
Emerging environmental stressors and oxidative pathways in marine organisms: Current knowledge on regulation mechanisms and functional effects
This review summarized current knowledge on how emerging environmental pollutants including microplastics, heavy metals, and other stressors trigger oxidative stress in marine organisms, examining regulatory mechanisms from pre-transcriptional to catalytic levels.
The Impact of Micro- and Nanoplastics on Aquatic Organisms: Mechanisms of Oxidative Stress and Implications for Human Health—A Review
This review examines how microplastics and nanoplastics cause oxidative stress, a harmful chemical imbalance, in aquatic organisms from plankton to fish. These tiny plastics accumulate in the food chain and may reach humans through seafood consumption. While the evidence of harm in aquatic species is growing, more research is needed to fully understand the implications for human health.
Exploring the impact of high salinity and parasite infection on antioxidant and immune systems in Coris julis in the Pityusic Islands (Spain)
Researchers examined how high salinity from desalination plant discharge and parasite infection affect the antioxidant and immune systems of a Mediterranean fish species. They found that elevated salinity combined with parasitic infection caused significant oxidative stress and immune suppression in the fish. The study suggests that coastal pollution from desalination may compound the effects of natural stressors on marine wildlife.
Do microplastics induce oxidative stress in marine invertebrates?
This review examined whether marine invertebrates exposed to microplastics show evidence of oxidative stress — a common cellular response to toxic injury — finding support for this effect across multiple species and polymer types. Oxidative stress is a key mechanism by which microplastics may harm marine organisms.
Anthropogenic modifications and their impacts on shellfish physiology
This thesis reviews how human activities — including aquaculture, coastal development, and pollution — have altered marine habitats over centuries, with consequences for shellfish physiology and ecosystem function. Shellfish are important sentinels for monitoring microplastic exposure and accumulation in coastal ecosystems.
Marine mussel metabolism under stress: Dual effects of nanoplastics and coastal hypoxia
This study examined how nanoplastics and low oxygen levels together affect marine mussels, finding that both stressors disrupted the animals' internal balance and energy metabolism. The combination of nanoplastics and oxygen-depleted water was more harmful than either stressor alone, damaging cellular defenses against oxidative stress. Since mussels are widely consumed as seafood, these findings raise questions about the safety of shellfish harvested from polluted, oxygen-poor coastal waters.
Does microplastic induce oxidative stress in marine invertebrates
This review examined whether microplastic ingestion induces oxidative stress in marine invertebrates, finding evidence that microplastics can elevate reactive oxygen species and disrupt antioxidant defenses in species including mussels, sea urchins, and copepods. Oxidative stress is a key mechanism through which microplastics may cause cellular damage in marine animals.
Editorial: The adaptation and response of aquatic animals in the context of global climate change
This editorial introduces a research topic collection exploring how aquatic animals adapt and respond to multiple stressors associated with global climate change, including ocean warming, acidification, and hypoxia. It synthesizes cross-cutting themes from contributed studies on synergistic, additive, and antagonistic interactions among environmental stressors affecting marine organism survival.
Economic and Ecological Impacts of Climate Change on Coastal Fisheries: A Global Analysis of Vulnerability and Adaptive Management Strategies
Researchers conducted a global analysis of how climate change compounds existing threats to coastal fisheries, including pollution from microplastics and other anthropogenic stressors. The study evaluated vulnerability across regions and assessed adaptive management strategies. The findings suggest that integrated approaches addressing both climate and pollution pressures are needed to sustain coastal fisheries.
Toxicity Induced by Micro-and Nanoplastics through Oxidative Stress: The Role of Co-Exposure to Other Chemical Pollutants
This review examined how micro- and nanoplastics cause oxidative stress — a form of cellular damage — in living organisms, particularly when combined with other chemical pollutants in the environment. Co-exposure to microplastics and chemicals like pesticides or heavy metals tends to be more damaging than either pollutant alone.
Consequences of Anthropogenic Changes in the Sensory Landscape of Marine Animals
This review examines how anthropogenic activities such as noise, light, chemical, and climate change are altering sensory cues in marine environments, impairing the ability of marine animals to navigate, find food, avoid predators, and reproduce.
The effect of climate change and microplastics on the physiology of marine invertebrates of economic interest
This thesis examines how climate change and microplastic pollution interact to affect the physiology of marine invertebrates important for aquaculture. Combined stressors were found to have compounding effects on organisms like mussels and oysters, threatening both ecosystems and food security.
Impacts of climate change on reactive oxygen species in seawater
This paper analyzed how climate change-driven reductions in ocean oxygen levels and declining pH affect hydrogen peroxide and superoxide concentrations, the most abundant reactive oxygen species in the ocean. Increased greenhouse gas emissions are projected to alter ROS dynamics with cascading effects on marine organisms experiencing oxidative stress.
Invertebrate responses to microplastic ingestion: Reviewing the role of the antioxidant system
Microplastic ingestion poses an oxidative challenge to invertebrates requiring upregulation of antioxidant defenses, but studies are limited to only seven taxa, dominated by polystyrene spheres <10 µm, and the lack of systematic experiments prevents identifying which specific microplastic characteristics drive the oxidative stress response.
Conflicts in the coastal zone: human impacts on commercially important fish species utilizing coastal habitat
This review looked at how human activities — including pollution, coastal development, and climate change — affect fish species that depend on coastal habitats in the Northeast Atlantic. The authors found that multiple overlapping stressors threaten commercially important fish populations, complicating fisheries management.
Assessment of oxidative stress, neurotoxicity, genotoxicity and prey-predator interactions in freshwater snails exposed to microplastics
This conference abstract investigates oxidative stress, nerve damage, DNA damage, and changes in predator-prey behavior in freshwater snails exposed to microplastics, pointing to a broad range of harmful biological effects. Understanding these impacts in aquatic invertebrates matters because they occupy important ecological roles and their exposure to microplastics can have cascading effects through food webs.
Mechanisms of Pollution Tolerance in Aquatic Organisms
This review examined how aquatic organisms tolerate pollution from heavy metals, organic compounds, and emerging contaminants such as microplastics, focusing on molecular, biochemical, and physiological adaptation strategies. Detoxification pathways including antioxidant responses and metallothionein induction were identified as central mechanisms.
Distribution and Uptake of Microplastics in Key Species of the Bulgarian Black Sea Ecosystem and Their Effects from a Stress Ecology Viewpoint

Redox Stress Burden of Trace Metals on Environmentally Dependent Ecosystem
This paper is not relevant to microplastics research — it is a broad review of how trace metals (heavy metals) accumulate in ecosystems and cause oxidative stress and health problems in living organisms.
Impact of micro- and nano-plastics on marine organisms under environmentally relevant conditions
This review summarized the impacts of micro- and nanoplastics on marine organisms including microalgae, crustaceans, snails, and fish at environmentally realistic concentrations. Researchers found that while some species showed tolerance at low concentrations, chronic exposure to nanoplastics in particular caused oxidative stress and behavioral changes. The study emphasizes that more research using real-world concentration levels is needed to accurately assess the risks microplastics pose to ocean life.
