  • Are PPD antioxidants effective in reducing tire wear?
  • It is reported that PPD antioxidants have been largely applied in commercial vehicle tire formulations (1–4% by mass). (11,35) Fomba et al. found a larger contribution of tire wear to the atmosphere particulates at a traffic-dominated site (2.0–2.9%) compared to an urban background (1.7–2.1%).
  • Are PPD antioxidants toxic?
  • An increasing number of studies have focused on the toxicity of these PPD antioxidants. (8−10,15,33) According to the European Chemical Agency, several of them were labeled as very toxic to aquatic life with long-lasting effects and harmful if swallowed and may cause an allergic skin reaction.
