Summary
Researchers developed and validated substrate-specific calibration curves for pyrolysis-GC/MS quantification of HDPE, PET, PP, PS, and PVC microplastics in organic-rich samples, demonstrating that matrix composition significantly affects analytical accuracy when using standard inorganic calibration matrices.
These dataset presents the results of the work entitled "Microplastic quantification in organic-rich samples: the relevance of testing substrate-specific calibration curves". Calibration curves for polymers HDPE, PET, PP, PS, and PVC were prepared within two solid inorganic matrices (silicon dioxide and glass fiber powders) and one solid organic-rich matrix (commercial peat-based substrate) for the quantification of these polymers within environmental samples. The dataset presents the values of the integrated peak areas for each selected pyrolytic marker for the selective quantification of microplastics. The integrated areas of the pyrolytic markers for the samples subjected to Fenton oxidation and for the spiked cultivation substrates are also presented.

Quantification of polystyrene microplastics in soils by pyrolysis-GC-MS: Effects of matrix and polymer molecular weight
Researchers investigated the effects of polymer molecular weight and soil matrix composition on pyrolysis-GC-MS quantification of polystyrene microplastics, finding that low molecular weight PS produced fewer pyrolysis markers than high molecular weight PS and that soil matrices caused up to 5-fold quantification errors depending on the marker selected. Addition of poly(4-fluorostyrene) as an internal standard helped minimize matrix effects, improving the reliability of this analytical method.
Pyrolysis-GC/MS Reference Data for Polymeric and Refractory Materials to Evaluate C-PVC Indicator Specificity
This paper provides a reference dataset of chemical fingerprints — generated by pyrolysis gas chromatography-mass spectrometry — to help researchers accurately identify chlorinated polyvinyl chloride (C-PVC) microplastics in environmental samples without confusing them with other materials. Environmental samples often contain complex mixtures of polymers, charcoal, soot, and natural materials that can produce overlapping signals, so having validated reference data is essential for reliable microplastic identification. Better analytical tools for distinguishing plastic types will improve the accuracy of microplastic contamination assessments.
