  • What are the TPS of rubber antioxidants?
  • The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
  • Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
  • Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
  • Are 6PPD and IPPD a contaminant?
  • 6PPD and IPPD were detected in white shrimp samples collected from aquafarms. Given the high toxicity of N- (1,3-dimethylbutyl)-N’-phenyl- p -phenylenediamine (6PPD) derivatives, such as 6PPD quinone (6PPDQ) to salmon, as well as their ubiquitous presence in the environment, the contaminant of aquatic food products has drawn significant attention.
  • What are unidentified chemicals and related transformation products (TPS)?
  • Many unidentified chemicals and related transformation products (TPs) are released into the environment during the life-cycle of commercial products. Efforts in evaluating their adverse impacts were usually not taken until these chemicals become globally ubiquitous.
