environmental fate of tire-rubber related pollutants 6ppd and 6ppd-q: a,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. this review synthesizes the existing data to assess the transformation, bioavailability, and.
what we know: 6ppd and 6ppd-quinone
figure 2. 6ppd in tires is converted to 6ppd-quinone (6ppd-q) when exposed to ozone. 6ppd-q is contained in tire wear particles that can be transported in the air and potentially inhaled by people. the particles can also be deposited on surfaces, soils, and
environmental rubber antioxidant 6ppd and toxicological,in terms of journal information, environmental science & technology letters, environmental science & technology, and science of the total environment rank as the top three publications for 6ppd and 6ppd-q. science of the total environment had the highest number of publications, accounting for 24.2 % of the total literature, with an average citation number of 9.
- 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.
- How does 6ppd-q interact with laboratory materials?
- In addition to interacting with suspended material and organic carbon, 6PPD-Q interacts with common laboratory materials. Because a short half-life precluded assessment of bottle, filter, and storage effects on 6PPD stability, 6PPD-Q laboratory procedures recommended herein were used for both compounds.
- 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).
- What are the effects of 6PPD & 6ppd-q in air and dust?
- Evaluating different Impacts of 6PPD and 6PPD-Q in air and dust. The presence of 6PPD and 6PPD-Q contributes to inhalation hazards by releasing particulate matter and volatile organic compounds into the air. Inhalation of these pollutants poses risks to respiratory health and may lead to various respiratory issues upon exposure.
