environmental occurrence and toxicity of 6ppd quinone, an emerging tire,n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is a chemical added to tires to prevent their oxidative degradation. 6ppd is highly reactive with ozone and oxygen, leading to the formation of transformation products such as 6ppd quinone (6ppdq) on the tire surfaces and, subsequently, in tire and road wear particles. 6ppdq is a toxicant that has been found in roadway runoff and.
environmental chemical rubber antioxidants
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.

recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
- Is 6PPD a toxic oxidant?
- To enhance tire durability, the antioxidant N- (1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone (6PPD-Q) when exposed to oxidants like ozone (O 3), causing ecological concerns.
- What causes 6ppd-q in soil and tire rubber wear particles (TRWPS)?
- There is a linkage between 6PPD-Q in soil and tire rubber wear particles (TRWPs), indicating its origin from sources associated with vehicular activities (Klockner et al., 2019). Approximately 50% of TRWPs can infiltrate the soil, releasing bound chemicals like 6PPD (Klockner et al., 2019).
- Can P-phenylenediamines be used in tires as anti-ozonants?
- There has been some research conducted on alternative anti-ozonants that can be used in tires as anti-degradants besides 6PPD. Other p-phenylenediamines (PPDs) have historically been used for this purpose, including IPPD, 7PPD, and 77PD. Many of these potential alternatives showed similar or superior performance in the lab as an anti-ozonant.
- Should policymakers and environmental regulatory agencies consider tire-related pollutants?
- We suggest that policymakers and environmental regulatory agencies take into consideration these measures. Implementing regulations to control tire-related pollutants, such as 6PPD and its transformation products, is crucial for mitigating their impact on the environment and human health.
