  • Are there alternatives to 6PPD as a rubber antioxidant?
  • Nevertheless, conclusive studies identifying superior alternatives to 6PPD as a rubber antioxidant remain scarce in the current literature. Urbanization has resulted in an increase in surface runoff, a phenomenon that plays a pivotal role in the transportation of chemicals originating from tire wear into aquatic environments.
  • Which industrial rubber additives have higher chemical concentrations?
  • Furthermore, we quantified 15 other industrial rubber additives (including bonding agents, vulcanization accelerators, benzotriazole and benzothiazole derivatives, and diphenylamine antioxidants), observing that PPD-derived chemical concentrations were 0.5–6 times higher than these often-studied additives.
  • Are PPD antioxidants present in all samples dominated by 6PPD and dtpd?
  • PPD antioxidants, PPDQs, and other TPs were present in all samples with chemical profiles dominated by 6PPD, DTPD, DPPD, and their corresponding PPDQs.
  • 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).
