ClearProgress on the Effects of Microplastics on Aquatic Crustaceans: A Review
This review examined the effects of microplastics on aquatic crustaceans, finding that microplastics negatively affect life history, behavior, and physiological functions including oxidative stress, immune responses, and reproductive output across multiple species.
Plastics in scene: A review of the effect of plastics in aquatic crustaceans
Researchers synthesized 10 years of literature on plastic pollution effects across nearly 100 crustacean species, finding that ingestion, bioaccumulation, and trophic transfer are the most studied endpoints, and that crustaceans — spanning marine, freshwater, and estuarine habitats — represent both highly vulnerable organisms and valuable bioindicators for assessing plastic contamination in aquatic food webs.
Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates
This review examined how a wide range of anthropogenic contaminants — including microplastics, pharmaceuticals, and pesticides — cause sub-lethal effects on aquatic invertebrates such as reduced growth, reproduction, and altered behavior. The study emphasizes that mixture exposures, common in real environments, can be more harmful than individual contaminants alone.
Microplastics, chlorpyrifos and their mixtures modulate immune processes in the terrestrial crustacean Porcellio scaber
Researchers investigated how polyester fiber and crumb rubber microplastics affect the immune system of the crustacean Porcellio scaber, alone and in combination with the pesticide chlorpyrifos. The study found that while microplastics at environmentally relevant concentrations caused only slight immune changes, mixtures of microplastics and chlorpyrifos produced different effects than either pollutant alone, suggesting microplastics may alter the bioavailability of co-occurring pesticides.
Do Waterborne Nanoplastics Affect the Shore Crab Carcinus maenas? A Case Study with Poly(methyl)methacrylate Particles
Researchers exposed shore crabs (Carcinus maenas) to waterborne nanoplastics and assessed multiple physiological endpoints, finding that nanoplastic exposure altered immune function, oxidative stress markers, and gene expression in ways that indicate significant sublethal harm to this ecologically important species.
Ecotoxicological effects of microplastics and adsorbed contaminants on aquatic organisms
This review summarizes ecotoxicological studies on microplastics and their adsorbed contaminants in microalgae, crustaceans, mollusks, and fish. Across all tested organisms, microplastics caused growth inhibition, reduced reproduction, and physiological stress — particularly when carrying additional chemical contaminants.
A review of current approaches for the study of microplastic contamination in crustaceans
This review assessed current methodological approaches for studying microplastic contamination in crustaceans, evaluating techniques for extraction, identification, and quantification while highlighting gaps in standardization that limit cross-study comparisons and risk assessment for these ecologically important invertebrates.
Sublethal Effects of Organophosphate Chlorpyrifos on Hemato-Immunological Parameters of the Gercacinid Crab, Cardiosoma armatum (Herklots, 1851)
Researchers exposed the land crab Cardiosoma armatum to low concentrations of the pesticide chlorpyrifos for 28 days, finding significant suppression of immune function and alterations in blood chemistry at sublethal levels. While focused on pesticide toxicity, the study demonstrates how chemical pollutants—including those that adsorb onto microplastics—can harm crustaceans even at low concentrations.
Ecological Exposure and Effects of Microplastics in Crabs Along the Pacific Coast
This study investigated how microplastic ingestion affects Pacific mole crabs — a common indicator species — finding that exposed crabs showed reduced predator avoidance ability, impaired reproductive output, and higher parasite loads. The results suggest that ecologically relevant levels of microplastic pollution can have cascading effects on both individual health and population dynamics in coastal crustaceans.
Ostracoda (Crustacea) as indicators of anthropogenic impacts – A review
This review examines how ostracods, tiny crustaceans found in lakes, rivers, and oceans, can serve as living indicators of water pollution from human activities including heavy metals, pesticides, and nutrient runoff. The authors note that ostracods have barely been studied in relation to microplastic contamination, presenting an opportunity for future research. Since these organisms are sensitive to water quality changes, they could become useful biological tools for monitoring microplastic pollution in aquatic environments.
Exposure and toxicokinetics of microplastics in arthropods: Mechanisms and consequences
This review synthesizes current knowledge on microplastic exposure routes and toxicokinetics in arthropods across diverse habitats, examining how MPs accumulate in insect, crustacean, and arachnid tissues and the mechanisms by which they cause physiological harm.
Microplastic pollution in wild populations of decapod crustaceans: A review
Researchers reviewed the occurrence and characteristics of microplastics found in wild populations of decapod crustaceans including crabs and shrimps. They found that fibrous microplastics smaller than 1 mm were the most commonly detected type, and that edible portions generally contained fewer microplastics than non-edible parts. The review highlights the importance of understanding microplastic contamination in commercially valuable crustaceans for both ecological and food safety assessments.
Effects of environmentally relevant concentrations of microplastics on amphipods
Researchers exposed two amphipod species to environmentally relevant polyethylene microplastic concentrations and found increased mortality and oxidative stress, with species-specific sensitivity suggesting ecological impacts even at low exposure levels.
Dissolved organic carbon and microplastics decrease the biodiversity effect on resource use efficiency of crustacean zooplankton
Researchers investigated how dissolved organic carbon and microplastics affect the relationship between biodiversity and ecosystem functioning in crustacean zooplankton communities. The study found that both pollutants diminish the positive effects that species and functional diversity normally have on resource use efficiency, suggesting that environmental contamination can undermine ecosystem resilience.
Microplastics in decapod crustaceans: Accumulation, toxicity and impacts, a review
This review summarizes research on microplastic contamination in decapod crustaceans like shrimp, crabs, and lobsters, which are widely consumed as seafood. Studies have found microplastics accumulating in their gills, digestive organs, and gut, with experimental evidence showing oxidative stress, immune damage, and reproductive toxicity. The findings raise concerns about potential human exposure to microplastics through seafood consumption.
Infochemicals Recognized by Crustaceans
This review examines the chemical communication systems of crustaceans, detailing how infochemicals mediate foraging, predator detection, mating, and social hierarchy, and discusses how anthropogenic pollution -- including heavy metals and microplastics -- threatens chemosensory function and thus crustacean ecological fitness.
Heavy metals and metalloid in aquatic invertebrates: A review of single/mixed forms, combination with other pollutants, and environmental factors
This review examines how heavy metals affect aquatic invertebrates, both alone and in combination with other pollutants like microplastics. When heavy metals attach to microplastics, the combined effect on organisms can be greater than either pollutant alone. Since these contaminants accumulate up the food chain, they ultimately pose risks to human health through seafood consumption.
The single and combined effects of mercury and polystyrene plastic beads on antioxidant-related systems in the brackish water flea: toxicological interaction depending on mercury species and plastic bead size.
Exposure of small crustaceans to mixtures of mercury and polystyrene plastic beads showed complex toxicological interactions — the effects depended on both the size of the plastic beads and the chemical form of mercury. The findings highlight that the real-world health risks of plastic pollution cannot be understood in isolation from the other chemicals that co-occur with plastics in aquatic environments.
Parasites of invasive crustacea: risks and opportunities for control
This review examined parasites of invasive crustacean species and their potential as biological control agents, discussing both risks and opportunities for managing invasive populations. While focused on crustacean parasitology rather than microplastics, the work is relevant to understanding the health of commercially important shellfish species.
Impacts of microplastics and pesticides on Daphnia
Researchers investigated the combined and individual impacts of microplastics and pesticides on Daphnia magna, a model crustacean widely used in freshwater ecotoxicology, to assess how these co-occurring pollutants affect aquatic ecosystem health. The study examined survival, reproduction, and physiological responses in D. magna exposed to varying concentrations of both stressors under controlled conditions.
Exploring the combined interplays: Effects of cypermethrin and microplastic exposure on the survival and antioxidant physiology of Astacus leptodactylus
Crayfish exposed to both microplastics and the pesticide cypermethrin for 60 days showed significant biochemical stress including reduced antioxidant defenses, altered blood chemistry, and liver tissue damage. The combination of these two common environmental contaminants appeared to be more harmful than either alone. This matters because aquatic organisms are often exposed to multiple pollutants simultaneously, and the combined effects could affect the safety of freshwater species consumed by humans.
Microplastics as contaminants in commercially important seafood species
This review summarizes evidence that microplastic ingestion is widespread in commercially important seafood species including mollusks, crustaceans, and fish. Evidence indicates that microplastics can affect physiology, reproductive success, and survival in marine organisms, and may also act as vectors for chemical pollutants. The study highlights the potential for human exposure to microplastics through seafood consumption, though the full health implications remain to be determined.
The ecotoxicological impact of microplastics on freshwater invertebrates
This review summarizes the ecotoxicological effects of microplastics on freshwater invertebrates, finding evidence of harm including reduced feeding, growth, and reproduction across multiple species. Because invertebrates are key links in food webs, these effects could have broader consequences for freshwater ecosystems.
Effects of micro‐ and nanoplastics on the physiology and metabolism of Portunus trituberculatus
Researchers exposed the swimming crab Portunus trituberculatus to micro- and nanoplastics (MNPs) and assessed physiological and metabolic responses across different tissues, finding that while lethal effects were minimal, MNPs triggered significant stress responses. Nanoplastics produced more severe effects than microplastics, with tissue-specific differences in enzyme reactions suggesting differential organ-level sensitivity to MNP contamination.
