ClearA 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.
Fate of microplastics and emerging contaminants: Mechanisms of interactions, bioaccumulation and combined toxicity to aquatic organisms
This review summarizes how microplastics interact with other emerging contaminants in water, finding that microplastics can absorb pollutants at concentrations up to a million times higher than surrounding water and carry them into living organisms. The combined toxicity of microplastics plus these hitchhiking chemicals is often greater than either alone, and these pollutants can reach humans through the food chain.
Interaction of Environmental Pollutants with Microplastics: A Critical Review of Sorption Factors, Bioaccumulation and Ecotoxicological Effects
This critical review examines how microplastics interact with and enhance the toxicity of co-occurring environmental pollutants including heavy metals, persistent organic compounds, and pharmaceuticals, synthesizing evidence on sorption mechanisms and combined ecotoxicological effects.
A critical review of the adsorption-desorption characteristics of antibiotics on microplastics and their combined toxic effects
This systematic review examines how microplastics absorb and release antibiotics in the environment, and the combined toxic effects of this interaction. When microplastics carrying antibiotics are ingested by living organisms, they may promote antibiotic resistance and cause greater harm than either pollutant alone, which is a growing concern for human health.
Synergistic Pollution: Interactions Among Polyethylene, Surfactants, and Antibiotics in an Aquatic Environment
Researchers investigated synergistic pollution effects among polyethylene microplastics, surfactants, and antibiotics in aquatic systems, finding that co-presence enhanced the environmental persistence and bioavailability of antibiotics beyond what microplastics or surfactants caused individually.
Source, transport, and toxicity of emerging contaminants in aquatic environments: A review on recent studies
This review examines emerging contaminants in water, with a focus on how microplastics act as carriers for other pollutants due to their strong ability to absorb chemicals. When microplastics carry these hitchhiking pollutants, the combined effect on aquatic organisms can be amplified thousands of times as they move up the food chain. The findings highlight how microplastic pollution does not just add plastic to the environment but also concentrates and transports other harmful chemicals toward humans.
Co-occurence of antibiotics and micro(nano)plastics: a systematic review between 2016-2021
This systematic review examines how microplastics and antibiotics interact in the environment. It finds that microplastics can absorb and carry antibiotics, potentially spreading antibiotic resistance and creating combined health risks that are greater than either pollutant alone.
Ecotoxicological Effects of Microplastics Combined With Antibiotics in the Aquatic Environment: Recent Developments and Prospects
This review examines how microplastics and antibiotics interact in water environments, finding that microplastics can absorb antibiotics onto their surfaces and carry them over long distances. When aquatic organisms encounter these antibiotic-laden microplastics, the combined toxicity can be worse than either pollutant alone. Microplastics also promote the spread of antibiotic resistance genes, which is a growing public health concern.
Toxic effects of triclosan in aquatic organisms: A review focusing on single and combined exposure of environmental conditions and pollutants
This review examines how triclosan, an antibacterial chemical found in many personal care products, harms aquatic organisms both on its own and in combination with other pollutants including microplastics. When triclosan and microplastics are present together in water, they can produce combined toxic effects that are worse than either alone. Since triclosan is widely used and microplastics are everywhere, their interaction in the environment is an important consideration for both ecosystem and human health.
Does triclosan adsorption on polystyrene nanoplastics modify the toxicity of single contaminants?
Researchers investigated whether triclosan adsorption onto polystyrene nanoplastics modifies the toxicity of each contaminant individually, using a multi-tiered approach to assess how nanoplastic carrier effects alter the combined hazard of this common antimicrobial agent in aquatic environments.
Effect of microplastics on the environmental behavior of emerging contaminants in aquatic matrices
This study examines how microplastics affect the environmental behavior of emerging contaminants in aquatic systems. Microplastics can adsorb other pollutants and alter their bioavailability, potentially increasing or decreasing toxic effects depending on the chemicals and environmental conditions.
Microplastics and environmental pollutants: Key interaction and toxicology in aquatic and soil environments
This review tracks how microplastics move through soil, water, and air ecosystems, acting as carriers for other pollutants like pesticides and heavy metals. When microplastics absorb these toxins, the combined effect on organisms can be worse than either pollutant alone. The paper highlights the need for better understanding of how these pollutant combinations affect ecosystems and ultimately human health through contaminated food and water.
Insight into combined pollution of antibiotics and microplastics in aquatic and soil environment: Environmental behavior, interaction mechanism and associated impact of resistant genes
This review examines the combined pollution created when microplastics absorb antibiotics in water and soil environments. Researchers found that microplastics can concentrate antibiotics on their surfaces, and this combination promotes the spread of antibiotic-resistant genes in microbial communities. The study highlights that the interaction between these two emerging pollutants may pose greater environmental and health risks than either one alone.
Interactions of microplastics and organic compounds in aquatic environments: A case study of augmented joint toxicity
Researchers investigated how polystyrene microplastics interact with the antimicrobial compound triclosan in simulated environmental and cellular conditions. They found that surface-functionalized microplastics adsorbed significantly more triclosan and released it under cellular conditions, with the combination producing greater toxicity to human intestinal cells than either contaminant alone. The study suggests that microplastics can amplify the harmful effects of co-occurring organic pollutants.
A tale of two emerging contaminants: Interfacial interactions, co-transport behaviors and ecotoxicological implications between per-and polyfluoroalkyl substances and micro(nano)plastics.
This review examined how PFAS and micro/nanoplastics co-occur in the environment, form interfacial adsorption complexes, and interact synergistically within organisms. The authors found that the two contaminant classes amplify each other's toxicity in co-exposure scenarios and that their shared transport pathways complicate standard risk assessment.
Microplastics as vectors for environmental contaminants in the food chain: Assessing the combined toxicological effects and bioavailability
This review examines how microplastics and nanoplastics act as carriers for environmental pollutants including heavy metals, organic chemicals, and microbial agents as they move through food chains. Researchers detail how polymer type, particle size, and environmental conditions influence the binding and release of these contaminants. The study highlights that the combined toxicity of microplastics together with the pollutants they carry may be greater than either would cause alone.
From co-occurrence to co-existence and co-exposure: Associations between per- and polyfluoroalkyl substances and microplastics in the environment
This review examines the growing recognition that PFAS chemicals and microplastics frequently co-occur in the environment and may interact in ways that affect both ecological and human health. Researchers identified four major sources that emit both pollutants simultaneously and found strong evidence that PFAS can adsorb onto microplastic surfaces and be co-transported through the environment. The study calls for standardized methods and long-term studies to better understand the combined exposure risks of these two widespread contaminant classes.
