  • 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).
  • 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.
  • What are the effects of 6PPD & 6ppd-q in air and dust?
  • Evaluating different Impacts of 6PPD and 6PPD-Q in air and dust. The presence of 6PPD and 6PPD-Q contributes to inhalation hazards by releasing particulate matter and volatile organic compounds into the air. Inhalation of these pollutants poses risks to respiratory health and may lead to various respiratory issues upon exposure.
  • Why is 6ppd-q present in soil?
  • The presence of 6PPD-Q in soil predominantly arises from the deposition of atmospheric particles or dust that carry 6PPD-Q. Soil samples collected from Hongkong's New Territories and Kowloon roadside showed varied concentrations of 6PPD-Q like 9.50–936 ng/g (Cao et al., 2022).
