S133 | MPLEACH | Chemicals Leaching from Microplastics
AI summary Read the abstract
This entry is a curated compound database (not a primary research paper) listing non-intentionally added substances and other contaminants that leach from four types of microplastics (PS, PA, PVC, PP) under standardized conditions, including after UV aging, compiled as part of the NORMAN NIAS trial.
A compound list of non-intentionally added substances (NIAS) and related leachate-derived contaminants identified using NTS workflows in the NORMAN NIAS trial. The list includes plastic additives, degradation products, polymer-specific NIAS, and emerging contaminants released from microplastics. Four polymer types (PS, PA, PVC, PP) were leached under standardized conditions in water and 1-propanol, with additional UV-aged PP and PVC samples exposed for 1000 hours. List provided by Nikiforos Alygizakis (EI), Jorg Roosma (TNO), Andrea Brunner (TNO) and Jaroslav Slobodnik (EI). Dataset DOI: 10.5281/zenodo.18157911. Note: Row 49 updated to CID 23274327 and respective information before release, since CID 136728566 was non-live.

pH-Responsive leaching profiles from photodegradation of microplastics
AI summary Read the abstract
Researchers systematically investigated the pH-dependent leaching of chemical additives and non-intentionally added substances (NIAS) from microplastics during photodegradation, examining how degradation products, residual monomers, and processing aids are released under varying environmental conditions. The study found that pH strongly governs the leaching profiles of hazardous chemicals from plastic particles, revealing a largely unregulated risk pathway in aquatic environments.
pH-Responsive leaching profiles from photodegradation of microplastics
AI summary Read the abstract
Researchers systematically examined how UV photodegradation of microplastics triggers pH-dependent release of chemical additives, non-intentionally added substances, and oligomers under controlled degradation conditions, characterising leaching profiles across a range of plastic polymer types. The study identified that pH strongly governs which hazardous compounds leach from degrading plastics and at what concentrations, revealing a mechanism by which environmental conditions modulate chemical risk from microplastic pollution.
Leaching behavior and toxic effect of plastic additives as influenced by aging process of microplastics
AI summary Read the abstract
This review examined how environmental aging processes affect the leaching behavior and toxicity of plastic additives from microplastics. Researchers found that UV exposure, weathering, and biological degradation alter the physicochemical properties of microplastics, increasing the release of harmful chemical additives and potentially amplifying their toxic effects on organisms in the environment.
Effects of chemical and natural ageing on the release of potentially toxic metal additives in commercial PVC microplastics
AI summary Read the abstract
Researchers aged commercial PVC microplastics under chemical and natural weathering conditions and measured release of potentially toxic trace metals added as stabilizers, finding that weathering significantly increased metal leaching rates, with cadmium and lead among the metals released.
