transformation products of tire rubber antioxidant 6ppd in,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. to address these data gaps, gas-phase ozonation of 6ppd was.

new evidence of rubber-derived quinones in water, air, and soil,five p-phenylenediamine-derived quinones have been identified to be pervasive in roadside soil, runoff water, and air particles, while their health risks remain elusive. research findings demonstrate the coexistence of five quinones from globally ubiquitous p-phenylenediamine antioxidants in urban runoff, roadside soils, and air particles. 1.
