Evolution of carbon mass fraction in remnants of granules and in microplastics as a function of post-aging carbonyl index.
AI summary Read the abstract
This study examines how the carbon mass fraction in remnants of polypropylene granules and in microplastics changes as a function of the carbonyl index following aging. The data provide a quantitative basis for tracking polymer degradation and carbon transformation during environmental weathering of plastic materials.
The carbon fractions presented are normalized using the stoichiometric proportion of carbon in PP.

Evolution of the proportion of initial Carbon retrieved in Microplastics as a function of post-aging carbonyl index.
AI summary Read the abstract
This study tracks the evolution of the proportion of initial carbon retrieved in microplastics as a function of the post-aging carbonyl index, providing a quantitative measure of carbon loss during environmental degradation of plastic particles. The findings contribute to understanding how polymer aging affects carbon accounting in microplastic degradation studies.
Relationship between the Carbonyl Index (CI) and Fragmentation of Polyolefin Plastics during Aging
AI summary Read the abstract
Researchers studied how polyethylene and polypropylene plastic films break down in simulated marine and coastal environments over 12 months, tracking the relationship between surface oxidation and the generation of microplastic fragments. They found a strong correlation between the carbonyl index, a measure of chemical degradation, and the number of secondary particles produced. The study identifies specific degradation thresholds beyond which plastic films begin to fragment into microplastics at accelerated rates.
Inter-Compartment Comparison of Weathering Extent of Microplastics Using Carbonyl Index and Its Application in Source Identification
AI summary Read the abstract
Researchers used carbonyl index measurements to quantify the weathering extent of microplastics collected from different environmental compartments—beach sand, river water, atmospheric deposition—and evaluated whether weathering extent can be used to identify plastic sources. Results showed that carbonyl index successfully distinguished microplastics from different exposure environments and could serve as a weathering fingerprint for source attribution.
Comparative evaluation of the carbonyl index of microplastics around the Japan coast
AI summary Read the abstract
Researchers evaluated the carbonyl index of nearly 3,000 polyethylene and polypropylene microplastic particles collected from coastal waters around Japan. The study found that the degree of weathering, as measured by the carbonyl index, varied by geographic location but showed no significant differences based on particle color or shape, providing insight into how microplastics degrade in marine environments.
Accessing the intrinsic factors of carbonyl index of microplastics: Physical and spectral properties, baseline correction, calculation methods, and their interdependence
AI summary Read the abstract
Researchers examined the intrinsic factors that influence the carbonyl index, a measure of microplastic degradation, including physical properties, spectral characteristics, and calculation methods. They found that baseline correction methods can significantly alter carbonyl index values, and that different calculation approaches yield inconsistent results. The study recommends standardized measurement protocols to improve the reliability of microplastic degradation assessments.
