Abstract N-(1, 3-dimethylbutyl)-N′-phenyl-p-phenylenediamine quinone (6PPDQ) has
attracted significant attention due to its highly acute lethality to sensitive salmonids …

The rubber antioxidant 6PPD has gained significant attention due to its highly toxic
transformation product, 6PPD-quinone (6PPDQ). Despite their detection in urines of …

Abstract A recently identified chemical, 2-((4-Methylpentan-2-yl) amino)-5-(phenylamino)
cyclohexa-2, 5-diene-1, 4-dione (6PPD-quinone; 6PPD-Q), is a transformation product of an …

The tire wear transformation product 6PPD-quinone (6PPDQ) has been implicated as the
causative factor for broad scale mortality events for coho salmon in the Pacific Northwest …

Recent identification of 6PPD‐quinone as the chemical causing acute toxicity in coho
salmon has led to substantial concern regarding the toxicity of this contaminant for other …

Abstract N-(1, 3-dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone (6PPDQ), one of
the oxidation products of rubber antioxidant 6PPD, has been identified as a novel toxicant to …

The huge consumption of the tire rubber antioxidant N-(1, 3-dimethylbutyl)-N′-phenyl-p-
phenylenediamine (6PPD) has resulted in pervasive contamination in aquatic environments …

N-(1, 3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone (6PPD-Q) is a recently
identified contaminant that originates from the oxidation of the tire antidegradant 6PPD …

We here report chemical characteristics relevant to the fate and transport of the recently
discovered environmental toxicant 6PPD-quinone (2-((4-methylpentan-2-yl) amino)-5 …

To enhance tire durability, the antioxidant N-(1, 3-dimethylbutyl)-N′-phenyl-p-
phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone …
