A combined thermodesorption and pyrolysis GC–MS approach reveals fragmentation and depolymerization products during plastic biodegradation

Researchers developed an analytical method combining thermodesorption and pyrolysis GC-MS to identify the full range of degradation products when bacteria break down polystyrene (PS) and polyvinyl chloride (PVC) plastics, detecting both soluble molecules and nano-scale polymer fragments. Understanding the complete spectrum of bacterial biodegradation products is essential for assessing whether microbial plastic degradation truly removes the hazard or simply converts it into different toxic forms.
