ClearUnderstanding and Mitigating the Toxic Impacts of Microplastic Pollution on Environmental Health
This review covers the sources, types, and ecological impacts of microplastics as environmental contaminants, examining how polymer-specific properties such as chemical additives affect toxicity across ecosystems and discussing mitigation approaches including physical and chemical remediation.
Microplastic Pollution
This review explains how microplastics carry two types of chemical threats: additives built into the plastic during manufacturing and pollutants like heavy metals that stick to plastic surfaces in the environment. With up to 16,000 chemicals potentially added to plastics during production, many of known toxicity, microplastics act as tiny vehicles delivering harmful substances to organisms that ingest them.
Les additifs issus des microplastiques : caractérisation, lixiviation et impacts
This review characterizes plastic additives leaching from microplastics into the environment, examining their physicochemical properties, leaching behavior, and biological impacts, and surveying the growing evidence that many plastic additives are toxic to organisms including marine wildlife and humans.
Chemical and ecotoxicological assessment of microplastics and emerging risks in the coastal environments
This review examines the chemical composition of microplastics found in coastal environments and assesses their ecotoxicological risks, including the leaching of plastic additives and adsorption of environmental pollutants. It emphasizes the need for better risk assessment frameworks that account for both the particles and their associated chemical contaminants.
Estimating the Mass of Chemicals Associated with Ocean Plastic Pollution to Inform Mitigation Efforts
Researchers estimated the mass of chemicals associated with ocean plastic pollution—including plastic additives that leach out and pollutants that adsorb onto plastic surfaces. The total chemical burden from ocean plastics is substantial, adding a chemical pollution dimension to the physical microplastic problem.
Plastic additives and microplastics as emerging contaminants: Mechanisms and analytical assessment
Researchers reviewed how chemical additives mixed into plastics during manufacturing — including stabilizers, flame retardants, and plasticizers — can leach out throughout a plastic's lifecycle and pose risks to ecosystems and human health, with microplastics acting as carriers that concentrate and transport these hazardous chemicals.
Toxic Chemicals and Persistent Organic Pollutants Associated with Micro-and Nanoplastics Pollution
Researchers reviewed how micro- and nanoplastics act as carriers for toxic chemical additives and persistent organic pollutants — like flame retardants and pesticides — making these contaminants more available and harmful once they enter food chains and human bodies. The review identifies major gaps in understanding how these chemicals detach from plastic particles inside living organisms and what health effects they cause.
Aquatic toxicity of chemically defined microplastics can be explained by functional additives
Researchers manufactured microplastics from four polymer types with precisely defined chemical compositions, including different additive formulations, and tested their toxicity to aquatic organisms. They found that the toxic effects of microplastics could largely be explained by the functional additives they contained rather than the base polymer itself. The study suggests that the chemical additives in plastics, not just the plastic material, are a primary driver of microplastic toxicity in aquatic environments.
Microplastic in marine organism: Environmental and toxicological effects
This review examined microplastics as a complex mixture of polymers, additives, and adsorbed environmental contaminants, and assessed their toxicological effects on marine organisms from ingestion and internal distribution. The authors emphasize that microplastic harm comes not only from the plastic itself but from the chemical cocktail it carries, and review the growing evidence for food web transfer.
Toxicity of plastic consumer products: a biological, chemical and social-ecological analysis
This study analyzed the toxic chemicals found in consumer plastic products, including additives, monomers, and processing by-products that can leach into food or the environment. The findings highlight that plastic toxicity extends beyond microplastic particles themselves — the chemicals embedded in plastics pose significant health risks through food packaging and environmental contamination.
(Micro)Plastics Are Toxic Pollutants
This review argues that microplastics should be considered toxic pollutants rather than merely physical hazards, citing evidence that they contain toxic chemicals within their structure and adsorb additional contaminants like PCBs, pesticides, and heavy metals from the environment. The study highlights research showing these chemicals can leach into the tissues of organisms that ingest microplastics, potentially causing harmful biological effects.
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.
Ecological Impacts of Microplastics and Their Additives
This comprehensive review examines how microplastics and their chemical additives cause ecological harm, covering exposure risks, toxicity pathways, and the transport of persistent toxic substances through ecosystems. Microplastics act as carriers for harmful chemicals that can accumulate in organisms and travel up the food chain toward humans. The review emphasizes that understanding the full life cycle of microplastics, from production to environmental breakdown, is essential for assessing risks to both ecosystems and human health.
A Detailed Review Study on Potential Effects of Microplastics and Additives of Concern on Human Health
This detailed review examines the potential health effects of microplastics and the chemical additives they contain, which can include plasticizers, flame retardants, and stabilizers. Researchers describe how humans are exposed to these hazardous chemicals through ingestion, inhalation, and skin contact as microplastics break down in the environment. The study emphasizes that the combination of physical particle effects and chemical toxicity makes microplastics a uniquely complex health concern.
Interaction of toxic chemicals with microplastics: A critical review
This critical review examined how toxic chemicals interact with microplastics in the environment, synthesizing evidence on adsorption, desorption, and the conditions under which microplastics either increase or decrease the bioavailability of co-occurring pollutants.
Is plastic debris toxic ?
This work examines the toxicity of plastic debris, reviewing evidence on the chemical and physical harm posed by plastic particles and their associated contaminants to biological systems. The publication is part of the international scientific literature assessing whether plastic pollution constitutes a direct toxic hazard.
New insights in to the environmental behavior and ecological toxicity of microplastics
This review provides new insights into how microplastics behave in the environment and their toxic effects on living organisms. Microplastics can absorb and carry other pollutants, making them more dangerous than the plastic alone, and their effects vary based on size, shape, and chemical composition. The review highlights that smaller particles, especially nanoplastics, pose the greatest risk because they can cross biological barriers and enter cells.
The polymers and their additives in particulate plastics: What makes them hazardous to the fauna?
This review argues that microplastics should not be treated as a single category because different plastic types have very different chemical properties and health risks. Each polymer carries its own set of chemical additives like flame retardants, plasticizers, and stabilizers, which can leach out and cause additional harm to organisms. Understanding the specific dangers of each plastic type and its additives is essential for accurately assessing the true health risks of microplastic exposure.
The toxicity of microplastics and its impact on marine organisms
This review essay summarizes the known toxic effects of microplastics on marine organisms, covering physical damage to the gastrointestinal tract, endocrine disruption from leached additives, and chemical harm from sorbed contaminants. The exact effects vary greatly depending on the organism, plastic type, associated chemicals, and environmental conditions.
Microplastics as a Vector of Hazardous Contaminants: Plastic Chemicals, Digestive Physiology and the Need for Chemical Simplification
This review explored how microplastics serve as vectors for hazardous chemicals, distinguishing between plastic-associated chemicals added during manufacturing and environmental pollutants adsorbed onto particle surfaces. The authors argue that the chemical burden of ingested microplastics warrants much more rigorous toxicological assessment.
