  • What is the content of 6PPD in rubber?
  • Typically, the content of 6-PPD in rubber materials ranges from 0.4% to 2% . During its production and use, 6-PPD can be transported to exposed surfaces and enter the environment. These antioxidants are highly reactive to ozone . 6-PPDQ is more stable than 6-PPD.
  • 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.
  • What are the primary sources of 6PPD & 6ppd-q?
  • The primary sources of 6PPD and 6PPD-Q in the environment are tire and road wear particles. In the atmosphere, 6PPD undergoes a reaction with ozone to form 6PPD-Q under conditions such as light and high temperature. In the pedosphere, the transformation of 6PPD-Q primarily occurs through heterogeneous iron reduction by microorganisms.
  • Where does 6ppd-q come from?
  • The generation of TWPs constitutes the primary source of 6-PPD found in dust (Wagner et al., 2022; Zhou et al., 2022). 6PPD-Q has been detected in indoor and outdoor dust samples in different locations such as parking lots and E-waste recycling workshops in southern China (Rausch et al., 2022).
