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.
Contribution of chemical toxicity to the overall toxicity of microplastic particles: A review
This review examines how the chemical toxicity of microplastics, from leached additives and absorbed pollutants, contributes to their overall harmful effects beyond just physical damage. Over 16,000 chemicals are used in plastic manufacturing, many of which can leach out and cause harm to living organisms at environmentally realistic concentrations. The findings suggest that the chemical cocktail carried by microplastics may be just as important as their physical presence when assessing health risks.
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.
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.
Emerging and legacy plasticisers in coastal and estuarine environments: A review
This review examined the occurrence and fate of legacy and emerging plasticizers in coastal and estuarine environments, highlighting the chemical risks posed by these plastic additives beyond the physical effects of microplastics themselves.
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.
Risk assessment of harmful types of plastics in the marine environment
This risk assessment evaluated the chemical hazards posed by residual additives and degradation products in seven types of microplastic particles found in the marine environment. The report identifies specific polymer types that pose the greatest risk to marine organisms through chemical leaching.
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.
Methods of analysing chemicals associated with microplastics: a review
This review surveys analytical methods used to identify and quantify chemicals associated with marine microplastics, covering extraction techniques, spectroscopic approaches, and the challenges of characterizing the complex mixture of polymer additives and adsorbed contaminants.
Understanding Interface Exchanges for Assessing Environmental Sorption of Additives from Microplastics: Current Knowledge and Perspectives
This review examines how chemical additives move between microplastics and the surrounding environment, including water, soil, and living organisms. The study highlights the complexity of these interactions and emphasizes that understanding how microplastics absorb and release chemicals is essential for properly assessing their environmental and health risks.
Additives and polymer composition influence the interaction of microplastics with xenobiotics
This study examined how chemical additives and structural composition of microplastics affect how they absorb environmental contaminants. Polymer additives significantly influence which toxic chemicals stick to microplastic surfaces, affecting how contaminants move through ecosystems.
Ecological and toxicological manifestations of microplastics: current scenario, research gaps, and possible alleviation measures
This review examines the ecological and toxicological effects of microplastics and their associated contaminants across aquatic and terrestrial environments, identifying key knowledge gaps and potential mitigation strategies. The authors emphasize that both physical particle effects and co-transported chemical pollutants pose compounding risks to wildlife and ecosystems.
Residual additives in marine microplastics and their risk assessment – A critical review
This review examines the chemical additives found in marine microplastics, including flame retardants, plasticizers, and UV stabilizers, and assesses the risks they may pose to ocean ecosystems. Researchers found that while the transfer of some chemicals from ingested plastics to organisms has been demonstrated, results on actual bioaccumulation are inconclusive. The study suggests that current risk assessment approaches may be inadequate given the sheer number of chemicals associated with marine plastic particles.
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.
A Review of Microplastics Risk Assessment in the Coastal Environment
This review examines the risk of microplastic pollution in coastal and marine environments, covering how microplastics transfer from land to sea, enter food chains, and pose combined toxic risks to marine life and human health. Chemical degradation processes like tire abrasion are identified as major sources of microplastics in coastal ecosystems.

Microplastics in the environment: Recent developments in characteristic, occurrence, identification and ecological risk
This review provides a comprehensive overview of microplastic pollution across oceans, freshwater, soil, and the atmosphere, examining their sources, movement patterns, and ecological risks. Researchers found that while coastal environments have been well studied, much less is known about microplastic contamination in terrestrial ecosystems. The study synthesizes data on microplastic toxicity, bioaccumulation in organisms, and environmental fate to support better risk assessment.
Ecotoxic effects of microplastics and contaminated microplastics – Emerging evidence and perspective
This review examined the ecotoxic effects of microplastics alone and when contaminated with other environmental pollutants. Researchers analyzed how microplastics' small size, surface properties, and hydrophobicity contribute to their environmental persistence and tendency to bind other contaminants. The study suggests that contaminated microplastics may pose greater ecological risks than pristine particles due to combined toxic effects.
Release of additives and non-intentionally added substances from microplastics under environmentally relevant conditions
Researchers measured how chemical additives leach out of different types of microplastics under realistic environmental conditions and found wildly different release rates — spanning five orders of magnitude over 64 days — highlighting that the type of plastic matters greatly when assessing the chemical risks microplastics pose to ecosystems.
