Does Calibration with Pristine PET Allow the Identification and Quantification of Aged PET Microplastic Particles by DSC?
AI summary Read the abstract
This study investigated whether differential scanning calorimetry calibrated with pristine PET can reliably identify and quantify aged, environmentally weathered PET microplastic particles. Because environmental microplastics undergo physical and chemical changes over time, developing analytical methods that accurately characterize aged particles is critical for realistic exposure assessments and pollution monitoring.
The microplastic (MP) pollution is recognised as one of the most challenging problems of the twenty-first century (Born and Brüll in The Science of the total environment 811, 2022). Due to inadequate waste management, plastic waste enters the natural...

Analytical Methods for Plastic (Microplastic) Determination in Environmental Samples
AI summary Read the abstract
Significant gaps remain in understanding how microplastics distribute and move through the environment, largely because reliable, fast analytical methods for monitoring them are still lacking. Developing standardized detection techniques is essential for generating the consistent data needed to assess true exposure levels and health risks across different ecosystems.
Micro and Nano Plastics: Identification and Quantification Methods
AI summary Read the abstract
Researchers reviewed the primary identification and quantification methods for micro and nanoplastics (MNPs), covering spectroscopic, microscopic, and chemical analytical techniques used to detect particles across environmental and biological matrices. Standardized, reliable detection methods are essential for accurately tracking MNP contamination levels and informing regulatory and public health responses.
Replicating real-world microplastics with accelerated physicochemical ageing
AI summary Read the abstract
Researchers developed methods to artificially age microplastics in the lab so they accurately replicate the physicochemical properties of microplastics found in real-world environments. Environmentally realistic aged microplastics are essential for generating reliable toxicology data, since fresh plastic particles behave differently than weathered ones that organisms actually encounter.
A Review on the Fate of Microplastics: Their Degradation and Advanced Analytical Characterization
AI summary Read the abstract
This review covers current methods for extracting, degrading, and analytically characterizing microplastics from environmental and biological samples, highlighting major gaps in photo-oxidation, biodegradation, and photo-thermal degradation approaches. Establishing effective microplastic degradation methodologies is essential for reducing their prolonged environmental persistence and preventing ongoing bioaccumulation of plastic fragments and associated toxic chemicals in food chains.
Methodologies for Microplastics Recovery and Identification in Heterogeneous Solid Matrices: A Review
AI summary Read the abstract
Researchers reviewed existing methods for extracting and identifying microplastics from solid environmental matrices such as soil, compost, sediment, and sludge, highlighting the lack of a standardized protocol as a key barrier to progress. Without consistent methodology, it is difficult to compare findings across studies or to set informed regulatory limits for microplastics in agricultural soils.
