Are there alternatives to 6PPD as a rubber antioxidant?

Nevertheless, conclusive studies identifying superior alternatives to 6PPD as a rubber antioxidant remain scarce in the current literature. Urbanization has resulted in an increase in surface runoff, a phenomenon that plays a pivotal role in the transportation of chemicals originating from tire wear into aquatic environments.

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.

Why is 6ppd-q important?

6PPD-Q in human samples highlight the need for further research on public health. N- (1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) is commonly used in rubber compounds as antioxidants to protect against degradation from heat, oxygen, and ozone exposure.

Do uncoated rubber infill materials exhibit high levels of 6PPD?

Recent studies have revealed that uncoated rubber infill materials exhibit high levels of 6PPD.

What causes 6ppd-q in soil & 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).

How can we address environmental implications of 6PPD & 6ppd-q effectively?

By promoting the utilization of advanced analytical methods and comprehensive research approaches, we can enhance our ability to assess and address the environmental implications of 6PPD and 6PPD-Q effectively. 6.12. Environmental management and policy framework
