Computational studies of rubber ozonation explain the effectiveness of 6PPD as an antidegradant and the mechanism of its quinone formation [PDF]
, 2022 The discovery that the commercial rubber antidegradant 6PPD reacts with ozone (\ce{O3}) to produce a highly toxic quinone (6PPDQ) spurred a significant research effort into non-toxic alternatives.

Environmental Toxicology and Chemistry, Volume 43, Issue 6, Page 1332-1338, June 2024.Abstract N‐(1,3‐dimethylbutyl)‐N′‐phenyl‐p‐phenylenediamine‐quinone (6PPD‐quinone) is a widespread contaminant of emerging concern resulting from oxidation of 6PPD, which is an antidegradant substance added to tires. The recent identification of 6PPD‐quinone as the cause of acute mortality in coho salmon has quickly motivated studies on 6PPD‐quinone ...

Mixture toxicity of 6PPD-quinone and polystyrene nanoplastics in zebrafish [PDF]
Plastic pollution, including micro- and nanoplastics, is a growing concern. Tyre-wear particles (TWPs) are the second largest source of microplastics in the ocean following abrasion of synthetic fibres.

Neurotoxicity from long-term exposure to 6-PPDQ: Recent advances
Ecotoxicology and Environmental SafetyThe recent acceleration of industrialization and urbanization has brought significant attention to N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine quinone (6-PPDQ), an emerging environmental pollutant from tire wear, due to its long-term effects on ...

Environmental Science & Technology LettersN-(1,3-Dimethylbutyl)-N’-phenyl-p-phenylenediamine quinone (6PPDQ) is an emerging tire-derived contaminant that poses a critical environmental risk to select salmonids. However, the mechanisms of 6PPDQ toxicity are currently unresolved. While species-specific metabolomic effects of 6PPDQ exposure have been explored, to our knowledge no studies have ...

Environmental Occurrence, Influencing Factors, and Toxic Effects of 6PPD-Q
ToxicsThe antioxidant N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is widely incorporated into tires to extend their service life. However, in the presence of ozone, it is readily transformed into N-(1,3-dimethylbutyl)-N′-phenyl-p-benzoquinone ...
