  • Are p phenylenediamine (PPD) antioxidants in recycled tire rubber products toxic?
  • Recently, roadway releases of N, N ′-substituted p -phenylenediamine (PPD) antioxidants and their transformation products (TPs) received significant attention due to the highly toxic 6PPD-quinone. However, the occurrence of PPDs and TPs in recycled tire rubber products remains uncharacterized.
  • Are rubber antioxidants toxic?
  • Recent advances in the toxicity issue of rubber antioxidant With the increasing popularity of automobiles, tire wear particles, generated from tire material during use on roads, would ultimately enter the eco-system, such as soil, aquatic environment, etc .
  • 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).
