Tyre Wear Particles in Stormwater: Why MBT and DPG Chemical Contamination Matters
Tyre wear particles (TWPs) are now recognised as a significant and largely unmanaged source of chemical contamination in urban stormwater. Among the most important tyre-derived chemicals are the vulcanisation accelerators mercaptobenzothiazole (MBT) and diphenylguanidine (DPG), which are used globally to produce durable, heat-resistant rubber. While essential to tyre performance, increasing evidence shows these additives pose […]
