  • Is 6PPD a toxic oxidant?
  • 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 (6PPD-Q) when exposed to oxidants like ozone (O 3), causing ecological concerns.
  • What causes 6ppd-q in soil and tire rubber wear particles (TRWPS)?
  • There is a linkage between 6PPD-Q in soil and tire rubber wear particles (TRWPs), indicating its origin from sources associated with vehicular activities (Klockner et al., 2019). Approximately 50% of TRWPs can infiltrate the soil, releasing bound chemicals like 6PPD (Klockner et al., 2019).
  • Which GC GC is used to identify 6PPD and fatty acid products?
  • An Agilent 8890 GC connected to a 5977B GC MSD with a DB-5 column was used to identify and quantify 6PPD and fatty acid products. The COSMO-RS method was used to perform solid–liquid solubility calculations. The Amsterdam Modeling Suite COSMO-RS was used.
  • How does microbial Fe (III) reduction affect the formation of 6ppd-q?
  • In the initial aging stage, microbial Fe (III) reduction transforms 6-PPD into 6PPD-Q (Xu et al., 2023b). Subsequently, the formation of 6PPD-Q is facilitated by environmentally persistent free radicals (EPFRs), resulting in the generation of O 2 •-, indicating the potential formation of 6PPD-Q without ozone presence (Xu et al., 2023b).
