Title of the PhD project:
Investigating the potential of analytical pyrolysis coupled to mass spectrometry in the study of particles derived from textile fibers and tire wear in the environment.

Abstract of the PhD project:
The intensive everyday usage of plastic materials causes the release of a large amount of microplastics (MPs) in the different environmental compartments. In particular, textile fibers and tire wear are considered major sources of MPs in water basins and sediments. The project will focus on the development and optimization of analytical protocols for the quali-quantitative characterization of textile fibers and tire-wear particles, related additives, and for the study of their physical-chemical behavior during degradation processes. Pyrolysis coupled with gas chromatography and mass spectrometry (Py-GC/MS), and Evolved Gas Analysis coupled with mass spectrometry (EGA-MS) will be the main employed analytical techniques, complemented by spectroscopic approaches and other chromatographic and mass spectrometric techniques.
The research project will provide advanced analytical tools and knowledge for a better evaluation of the impact of pollution related to textile micro-fibers and tire-wearing phenomena, in view of supporting monitoring and remediation strategies.
The results and knowledge obtained on the degradation processes of the investigated polymeric materials will be highly transferable to the fields of material science, textile research and heritage conservation.
