The hidden chemicals in our Tyres - Are they cause for Concern?

From Tyres to Our Bodies: Are These Hidden Chemicals a Cause for Concern?

Two chemicals used in tyre manufacturing, 2-mercaptobenzothiazole (MBT) and 1,3-diphenylguanidine (DPG), are increasingly attracting attention as environmental pollutants. These tyre rubber accelerators can enter road runoff and aquatic environments through tyre wear, raising questions about potential human exposure and health effects. This article by Master of Research (MRes) student at Cardiff University’s School of Biosciences, […]

Tyre Wear Paricles in Stormwater Road Run Off - MBT and DPG

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 […]
