This paper is not relevant to microplastics research — it examines the co-occurrence of the harmful algal toxin domoic acid and Vibrio bacteria in Pacific oysters in California, focusing on food safety risks from biological rather than plastic contaminants.
Single and combined effects of microplastics and lead on the freshwater algae Microcystis aeruginosa
Researchers tested the individual and combined effects of microplastics and lead (Pb) on the growth, photosynthetic pigments, and antioxidant responses of the freshwater cyanobacterium Microcystis aeruginosa. They found that microplastics alone inhibited growth while low-dose Pb promoted it, but their combination altered toxicity outcomes in complex ways depending on concentration, indicating that co-exposure risks in freshwater cannot be predicted from single-contaminant studies.
Assessment of toxic and behavioral effects of isolated and combined exposure of cladocerans (Daphnia similis and Moina micrura) to microplastics and cyanobacteria
This Brazilian study assessed the toxic and behavioral effects of cyanobacteria toxins and polymeric particles on cladocerans (Daphnia), two co-occurring contaminants in aquatic environments. Combined exposure produced distinct effects compared to individual exposures, highlighting the ecological complexity of multi-contaminant pollution.
Toxic effects and metabolic response mechanisms of amino-modified polystyrene nanoplastics and arsenic on Microcystis aeruginosa
Researchers investigated the combined effects of amine-modified polystyrene nanoplastics and arsenic on a common freshwater cyanobacterium. They found that co-exposure intensified cellular stress, disrupted metabolic processes, and promoted the release of harmful toxins beyond what either pollutant caused individually. The findings reveal previously unrecognized risks to freshwater ecosystems when nanoplastics interact with heavy metal contaminants.
Toxicological interactions of microplastics/nanoplastics and environmental contaminants: Current knowledge and future perspectives
This review examines how the combined presence of micro- and nanoplastics with other environmental contaminants like heavy metals, pesticides, and pharmaceuticals affects toxicity. Researchers found that plastic particles can alter the bioavailability and toxic effects of co-occurring pollutants, sometimes increasing harm to organisms, which complicates environmental risk assessment.
A review on the combined toxicological effects of microplastics and their attached pollutants
Researchers reviewed how microplastics act as carriers for other environmental pollutants — including heavy metals and persistent organic chemicals — and how these combinations produce toxic effects in organisms that are more severe than either contaminant alone. The findings highlight a complex, layered toxicity problem that affects microbes, invertebrates, and vertebrates across marine and terrestrial environments.
Synergistic reproductive toxicity of microcystin-LR and polystyrene micro/nano-plastics in male zebrafish.
Male zebrafish exposed to both microcystin-LR and polystyrene micro/nano-plastics showed synergistic reproductive toxicity, with co-exposure more severely impairing sperm quality, testicular structure, and reproductive hormones than either contaminant alone. The study underscored the ecological risk posed by the co-occurrence of cyanotoxins and microplastics in aquatic environments.
(Eco)Toxicology of Cyanobacteria and Cyanotoxins: From Environmental Dynamics to Adverse Effects
This review examines the ecotoxicology of cyanobacteria and cyanotoxins, covering the environmental dynamics driving harmful bloom formation under eutrophication and climate change, and the adverse effects of cyanotoxins on aquatic organisms, wildlife, and human health.
Integrative Evaluation of the Ecological Hazards by Microplastics and Heavy Metals in Wetland Ecosystem
Researchers conducted an integrative ecological hazard assessment of microplastics combined with heavy metals, evaluating their combined toxicity to aquatic organisms. The study found that co-contamination with heavy metals and microplastics poses greater ecological risk than either pollutant alone.
Mixed Contaminants: Occurrence, Interactions, Toxicity, Detection, and Remediation
This review examines how mixed environmental contaminants, including microplastics, heavy metals, pesticides, and pharmaceuticals, interact when present together in the environment. The study highlights that pollutant mixtures can produce synergistic toxic effects that are greater than the sum of individual pollutants, making combined contamination a more complex risk than single-pollutant assessments suggest.
Fate, abundance and ecological risks of microcystins in aquatic environment: The implication of microplastics
This review explores how microplastics in water can interact with microcystins, highly toxic compounds produced by harmful algal blooms, by adsorbing and transporting them through aquatic environments. The combination poses increased risks to human health because microplastics can carry these dangerous toxins into drinking water sources and through the food chain.
Synergistic effects of microplastics and cyanotoxins on the demography of the rotifer Brachionus calyciflorus Pallas
Researchers studied the combined effects of polystyrene microplastics and cyanobacterial toxins on the freshwater rotifer Brachionus calyciflorus. They found that while each contaminant alone reduced rotifer survival, reproduction, and feeding, the two together produced significantly stronger adverse effects. The study demonstrates that microplastics and cyanotoxins can act synergistically, amplifying their individual harm to aquatic zooplankton.
Understanding the Risks of Diffusion of Cyanobacteria Toxins in Rivers, Lakes, and Potable Water
This review covers the health risks of cyanobacteria (blue-green algae) toxins found in rivers, lakes, and drinking water, which can damage the liver and nervous system in humans. While not directly about microplastics, the research is relevant because microplastics in water can interact with cyanobacteria and their toxins, potentially serving as carriers that concentrate these harmful substances. The paper discusses various water treatment methods for removing cyanotoxins, many of which are also applicable to microplastic removal.
Coexistence of microplastics and heavy metals in soil: Occurrence, transport, key interactions and effect on plants
This review examines how microplastics and heavy metals like lead, cadmium, and arsenic interact in soil, often creating combined toxic effects on plants that differ from either pollutant alone. These interactions are relevant to human health because contaminated crops can transfer both microplastics and heavy metals to people through the food supply.
Complex interactions among temperature, microplastics and cyanobacteria may facilitate cyanobacteria proliferation and microplastic deposition
Researchers investigated how microplastics interact with temperature and nutrient conditions to affect cyanobacterial growth, finding that microplastics can alter cyanobacterial physiology and potentially exacerbate bloom formation under warming conditions.
Synergistic human health risks of microplastics and co-contaminants: A quantitative risk assessment in water
This study calculated the combined health risks of ingesting microplastics along with the toxic chemicals they carry, including heavy metals and plastic additives, and found that the combined hazard is far greater than from microplastics alone. Children face especially high risk, and the interaction between microplastics and co-contaminants creates synergistic effects that standard risk assessments may significantly underestimate.
Changes in population fitness and gene co-expression networks reveal the boosted impact of toxic cyanobacteria on Daphnia magna through microplastic exposure
Researchers found that exposing the water flea Daphnia magna to both toxic cyanobacteria and microplastics together produced worse health effects than either stressor alone, reducing population fitness and altering gene expression patterns. The study suggests that as plastic pollution and harmful algal blooms increasingly overlap in lakes and rivers, aquatic organisms may face compounding threats that are greater than the sum of their parts.
Higher toxicity induced by co-exposure of polystyrene microplastics and chloramphenicol to Microcystis aeruginosa: Experimental study and molecular dynamics simulation
Researchers studied what happens when the antibiotic chloramphenicol and polystyrene microplastics are present together in water containing blue-green algae. The study found that the combined exposure was more toxic to the algae than either pollutant alone, disrupting photosynthesis and gene expression. The findings suggest that microplastics and antibiotics may interact in ways that amplify their harmful effects on aquatic ecosystems.
Toxicity effects of microplastics and nanoplastics with cadmium on the alga Microcystis aeruginosa
Researchers examined the combined toxicity of microplastics, nanoplastics, and cadmium on the freshwater alga Microcystis aeruginosa. The study found that while cadmium alone was most toxic, the combination of plastics and cadmium produced synergistic harmful effects, with nanoplastics causing greater cadmium release and more severe disruption to algal cell membranes than microplastics.
