2023 SETAC Poster: The Fate of 6PPD-quinone in Soil and Water-Sediment Systems using a 14C Radiotracer
The antiozonant and antioxidant 6PPD (N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine) and its transformation product 6PPD-quinone (6PPD-Q) are believed to be carried from tire and road wear particles (TRWP) and washed into watercourses. Some publications have identified 6PPD-Q as a contributor to Urban Runoff Mortality Syndrome (URMS) of a single specific fish species, Coho salmon.
The environmental fate in soils, water-sediment systems and surface- waters has been investigated using 14C-6PPD-Q to track the partitioning and transformation products.
This presentation focuses on the initial results, including identification and quantification of transformation products generated during these studies.
Rory Mumford presented this research at the SETAC North America 44th Annual Meeting in Louisville, Kentucky.
