  • 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.
  • Does 6PPD survive pyrolysis?
  • The liquid pyrolysis oil product distribution and solid carbon black powder from the 1.3 mm and 0.6 mm particles are independent of the starting particle size (Fig. 1d); however, gas chromatography–mass spectrometry (GC–MS) of the oil product shows that 6PPD survives appreciably after pyrolysis (Supplementary Fig. 10).
  • Are phenylenediamine and 6PPD a pervasive pollutants in human urine?
  • Du, B. et al. First report on the occurrence of N - (1,3-dimethylbutyl)- N ′-phenyl- p -phenylenediamine (6PPD) and 6PPD-quinone as pervasive pollutants in human urine from south China. Environ. Sci. Technol. Lett.9, 1056–1062 (2022).
