Identification of polymer types and additives in marine microplastic particles using pyrolysis-GC/MS and scanning electron microscopy
Researchers used pyrolysis and thermal analysis to identify polymer types and plastic additives in marine microplastic particles, finding a diverse range of polymers and additive chemicals in samples from multiple ocean environments.
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.
Plastic additives in the ocean: Use of a comprehensive dataset for meta-analysis and method development
Researchers compiled the first comprehensive database of studies measuring the more than 13,000 chemical additives — including plasticizers, flame retardants, and antioxidants — that are mixed into plastics and can leach into ocean water, sediment, and marine life. Their meta-analysis revealed major gaps in what's being monitored, with only a small fraction of known additives currently being tested for in marine environments.
Oceanic Long-Range Transport of Organic Additives Present in Plastic Products – An overview
This review examined the oceanic long-range transport of chemical additives leaching from marine plastic debris, finding that persistent synthetic polymer matrices release significant quantities of additives — including plasticizers, flame retardants, and antioxidants — that can travel globally via ocean currents.
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.
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.
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.
Development of a dispersive liquid–liquid microextraction method for the determination of plastic additives in seawater
Researchers developed a sensitive liquid-liquid microextraction method to detect seven plastic additive chemicals — including phthalates, triclosan, and antioxidants — in seawater, achieving good recovery and detection limits in the parts-per-billion range. These additives leach from microplastics into surrounding water and carry their own toxicity, meaning the chemical contamination from plastic pollution extends well beyond the physical particles themselves.
Screening and Quantification of Micro(Nano)Plastics and Plastic Additives in the Seawater of Mar Menor Lagoon
Researchers analyzed seawater from Mar Menor lagoon in Spain for micro- and nanoplastics, detecting a wide range of polymer types along with plastic additives including phthalates, UV stabilizers, and flame retardants. Both the plastic particles and the chemical additives they carried were present in the lagoon water. This study demonstrates that plastic pollution in coastal lagoons includes not just physical plastic particles but a complex cocktail of toxic chemical contaminants.
Release of chemical additives and potentially toxic elements from plastics under ambient outdoor environmental conditions
Researchers placed large pieces of seven commercial plastic polymers outdoors under natural conditions for extended periods and measured the release of phthalates, phenolic compounds, and polybrominated diphenyl ethers, finding that realistic environmental conditions cause significant leaching of toxic chemical additives.
Occurrence and effects of plastic additives on marine environments and organisms: A review
This review examines chemical additives found in plastics, such as flame retardants, phthalates, and bisphenol A, and how they leach into the marine environment as plastics accumulate and fragment. Researchers summarize evidence showing that these additives have been detected in marine water, sediment, and organisms, and can transfer from ingested plastic into animal tissues. The findings highlight that the chemical risk from plastic additives deserves as much attention as the physical impacts of microplastic particles themselves.
Effects of aging on environmental behavior of plastic additives: Migration, leaching, and ecotoxicity
This review examines how the aging and weathering of microplastics in the environment causes chemical additives like plasticizers, flame retardants, and antioxidants to leach out. As microplastics age through UV exposure, heat, and biological activity, they release these additives more readily, increasing the toxic risk to organisms. The findings are important because they show that older, weathered microplastics found in the real world may be more chemically hazardous than fresh plastics used in most lab studies.
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.
Environmental behaviors of microplastics in aquatic systems: A systematic review on degradation, adsorption, toxicity and biofilm under aging conditions
Aging processes like UV irradiation and physical abrasion alter microplastic surface properties, increasing their capacity to adsorb environmental pollutants while also enhancing leaching of toxic additives like phthalates, collectively amplifying the environmental toxicity of weathered microplastics.
Oceanic long-range transport of organic additives present in plastic products: an overview
Researchers analyzed how chemical additives — such as flame retardants and plasticizers — leach slowly from floating plastic debris and can be carried by ocean currents to remote regions like the Arctic, estimating that roughly 8,100 to 18,900 tonnes of these chemicals travel globally via plastic each year. The study highlights plastic debris as a long-range transport vehicle for toxic chemicals that would otherwise break down before reaching polar ecosystems.
Recent advances on microplastic aging: Identification, mechanism, influence factors, and additives release
This review found that environmental aging transforms microplastic surface properties through abrasion, chemical oxidation, UV irradiation, and biodegradation, altering their environmental behavior and ecological risk. Aging also triggers the release of toxic plastic additives, but significant gaps remain between laboratory aging simulations and real-world conditions.
