  • 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 GC GC is used to identify 6PPD and fatty acid products?
  • An Agilent 8890 GC connected to a 5977B GC MSD with a DB-5 column was used to identify and quantify 6PPD and fatty acid products. The COSMO-RS method was used to perform solid–liquid solubility calculations. The Amsterdam Modeling Suite COSMO-RS was used.
  • Are Tire-Rubber pollutants harmful to human health?
  • 2. Future research will prioritize assessing the ecological and human health risks associated with tire-rubber related pollutants since it has been detected in human urine (Du et al., 2022). This includes going into the ecological repercussions on soil ecosystems, plant health, and terrestrial as well as aquatic food webs.
  • Does acetone remove 6PPD from waste rubber?
  • A parity plot of the measured extraction efficiency versus the calculated 6PPD solubility (Fig. 2e) corroborates that solubility is a crucial determinant of the solvent’s ability to remove 6PPD from waste rubber and confirms that acetone is one of the best solvents while being inexpensive and non-toxic.
