2024 SETAC Europe Poster: The Fate of 6PPD-quinone in Soil and Water-Sediment Systems using a 14C Radiotracer

6PPD-quinone (6PPD-Q), a transformation product of the antiozonant and antioxidant 6PPD (N-(1,3-Dimethylbutyl)-N′-phenyl-phenylenediamine), is believed to be carried from tire and road wear particles (TRWP) 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 potential mobility of 6PPD-Q in soils and sediments has been investigated using the OECD 106 test guideline (Adsorption - Desorption Using a Batch Equilibrium Method) and 14C-radiolabelled 6PPD-Q. This study is used to indicate how likely a compound is to move through soils.
Additionally, the transformation of 6PPD-Q has been investigated according to OECD test guidelines 307 (Aerobic and Anaerobic Transformation in Soil), OECD 308 (Aerobic and Anaerobic Transformation in Aquatic Sediment Systems) and OECD 309 (Aerobic Mineralisation in Surface Water – Simulation Biodegradation Test). These studies were selected to allow us to gain an understanding of the transformation and partitioning of 6PPD-Q in the key environmental compartments.
Initial results were presented at SETAC North America (Louisville, November 2023). This presentation summarises the findings, including identification and quantification of transformation products generated during these aforementioned studies.
Rory Mumford will present this research at the SETAC Europe 34th Annual Meeting, 5-9 May 2024, in Seville, Spain. (Wednesday, 8 May, Location: 3.21.P-We219)
