Independent VOC analysis of European and American market tire particles

In 2022 we presented the results of our initial research following analysis of 200 European tires. In 2023 we will be sharing findings from approximately 800 tires from both European and American sources. Each tire wear sample is then analyzed utilizing gas chromatography and mass spectrometry (GCxGC-TOF-MS) following pyrolysis to identify the presence of hundreds of organic chemicals and their concentrations in the sample. The pyrolysis degradation process is useful for understanding the structure of the polymer but also for determining what smaller molecules could possibly leach into the environment (Ladak, 2021) (Greta Biale, 2021).
