Infographhic: Sources of Total Suspended Solids (TSS) in road run off and contaminants that bind to them.

Total Suspended Solids in Road Runoff and Associated Contaminants

Stormwater, , , , , ,

What are Total Suspended Solids? In stormwater runoff, Total Suspended Solids (TSS) refers to undissolved solid particles larger than 0.45µm. Anything smaller is considered a dissolved substance. Pollutants can bind to or become trapped within these solid particles, making TSS a highly effective contaminant transport mechanism from surface road runoff into receiving water bodies. In […]

Tyre Wear Particles in Stormwater: Why MBT and DPG Chemical Contamination Matters

Stormwater, , , , , , , ,

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 […]
