  • 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.
  • Does 6PPD ozonation pose environmental risks?
  • 6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation.
  • Which PPD-Q compounds are found in tire rubber granules?
  • Among the various PPD-Q compounds identified in tire rubber granules (12 μg/g), rubber crumbles (0.3–25 μg/g), and recycled rubber door mats (11–26 μg/g), 6PPD-Q stands out as the most prevalent (Zhao et al., 2023b). Research indicates that sunlight not only catalyzes the formation of 6PPD-Q in TRWPs but also accelerates its breakdown.
  • Is 6PPD a common compound in tire tread particles leachate?
  • The study revealed that 6PPD was among the most prevalent compounds in the leachate of micron-sized tire tread particles, while its presence was less pronounced in centimeter-sized tire tread particles leachate.
