  • 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.
  • Is 6PPD recalcitrant under harsh pyrolysis?
  • This demonstrates the recalcitrant nature of 6PPD under harsh pyrolysis conditions and suggests solvent extraction is necessary for its removal. The TGA curve (Supplementary Fig. 11) of 6PPD shows a maximum degradation at ~300 °C and suggests that some 6PPD in the tires may sublime into the liquid product before the rubber degrades.
  • Is 6ppd-q toxic?
  • 6PPD-Q pose hazards to certain aquatic and terrestrial organisms at low concentrations. Toxic effects include neurobehavioral changes, reproductive dysfunction, and others. Toxic mechanisms include mitochondrial stress, DNA adducts, and lipid metabolism. 6PPD-Q in human samples highlight the need for further research on public health.
  • 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.
