Since publishing my last paper at the end of 2024, research on the impact of 6PPD and its derivative, 6PPD-quinone (6PPD-q), on fish, mammalian, and human health has made considerable progress. As a brief overview, 6PPD is a common tyre additive and is therefore released into highway water runoff in environmentally significant concentrations. 6PPD is […]
Understanding PAHs in Stormwater Runoff Stormwater runoff is a significant pathway for pollutant transport into receiving water bodies. Among these pollutants, Polycyclic Aromatic Hydrocarbons (PAHs) are a main concern in stormwater treatment, due to their persistence and toxicity in our environments. Particle Size Distribution (PSD) aids in determining how PAHs behave- in terms of their […]
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 (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 […]
Tesni Hyett is studying BioMedical Sciences at Cardiff University. She is the daughter of 3P Technik UK’s Director Glyn Hyett. During the summer break between her 2nd academic year and 3rd-year professional training year at Sapienza University of Rome, Italy, researching Oncology, Glyn asked Tesni to research 6PPD in Stormwater. Glyn had read some articles […]
