  • 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 countries import products from Ethiopia?
  • Other leading sources of imports are India ($2.7bn, 15% of total) followed by UAE, Saudi Arabia, Kuwait, Turkey, and the US—all of whom each sold close to $1bn worth of products in the Ethiopian market last fiscal year.
  • Can antioxidant protection be used to detect PPDS and TPS?
  • An efficient and stable method for the detection of PPDs and their TPs was developed. Oxidative degradation is the main cause of low extraction efficiency of PPDs and some TPs. Combined strong antioxidant protection for stable extraction PPDs and their TPs was first proposed.
  • Can acetonitrile salt-out assisted extraction be used to extract PPDS?
  • Therefore, an acetonitrile salt-out assisted extraction method was identified for extracting PPDs and their TPs in aquatic products. However, recoveries for 6PPD, IPPD, 4-ADPA, and 4-HDPA are still less than 50% (Table S6), and further development of methods is needed.
