tire-derived contaminants 6ppd and 6ppd-q: analysis, sample,one such chemical is 6ppd-quinone (6ppd-q), a transformation product of the tire antioxidant 6ppd. in urban stormwater runoff 6ppd-q can exceed acute toxicity thresholds for several salmonid species and is being implicated in significant coho salmon losses in the pacific northwest.
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
environmental fate of tire-rubber related pollutants 6ppd
recent findings indicate the detection of 6ppd-q in 95% of samples from the pearl river estuary (pre), with a 100% detection frequency observed in surficial sediment samples collected from urban rivers in the prd and the south china sea (scs) coast (zeng et al., 2023).
big discount rubber antioxidant 6ppd for tyre,this study reports occurrences of five compounds derived from tire rubber, including the recently discovered transformation product 6ppd-quinone, in stormwater and snowmelt runoff in the semiarid, cold-climate city of saskatoon, saskatchewan, canada.

6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase...
tire-rubber related pollutant 6-ppd quinone: a review of its,exposure to 6-ppdq at environmentally relevant concentrations could induce several types of toxicity, including neurotoxicity, intestinal toxicity, and reproductive toxicity. this review also identifies and discusses knowledge gaps and research needs for the study of 6-ppdq.
environmental profiles, hazard identification, and- pubmed
recent findings of 6ppd-q in human samples, such as blood, urine, and cerebrospinal fluid, underscore the importance of further research on the public health and toxicological implications of these compounds.
transformation products of tire rubber antioxidant 6ppd for sale,abstract: 6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
environmental fate of tire-rubber related pollutants 6ppd
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 …
new evidence of rubber-derived quinones in water, air for sale,by investigating this phenomenon, we identified a highly toxic quinone transformation product of n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd), a globally ubiquitous tire rubber antioxidant.
