What evidence exists on the environmental occurrence and toxic effects of the tire additive 6PPD: a systematic map protocol [PDF]

Environmental Evidence
Background The tire additive N-(1,3-dimethylbutyl)-Nʹ-phenyl-p-phenylenediamine (6PPD) is widely produced in large volumes as a rubber antidegradant. This chemical can be released into the environment throughout the lifecycle of rubber products. Recently,

Toxicological effects of 6PPD and 6PPD quinone in zebrafish larvae

Journal of Hazardous Materials, 2022
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) is the most widely used antioxidant in automobile tyres and many rubber products. We investigated the impact of 6PPD and 6PPD quinone on acute toxicity, morphology, swimming behaviour, heart rate, and oxygen consumption in zebrafish larvae. Zebrafish embryos were exposed to 6PPD and 6PPD quinone

Reactive oxygen species and chromophoric dissolved organic matter drive the aquatic photochemical pathways and photoproducts of 6PPD-Quinone under simulated high-latitude conditions [PDF]

, 2023
The photochemical degradation pathways of 6PPD-quinone (6PPDQ, 6PPD-Q), a toxic transformation product of the tire antiozonant 6PPD, were determined under simulated sunlight conditions typical of high-latitude surface waters.

Presence of 6PPD-quinone in runoff water samples from Norway using a new LC–MS/MS method

Frontiers in Environmental Chemistry, 2023
The chemical 6PPD-quinone is highly toxic to some fish species of the Oncorhynchus and Salvelinus genera and is the oxidation product of the common car tire additive 6PPD.

Chiral perspective evaluations: Enantioselective hydrolysis of 6PPD and 6PPD-quinone in water and enantioselective toxicity to Gobiocypris rarus and Oncorhynchus mykiss

Environment International, 2022
As a ubiquitous tire antidegradant, N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD) is persistently released into the environment. It is highly toxic to aquatic organisms, and its transformation product 6PPD-quinone (6PPD-Q), is “very highly ...

Recycled silica as a renewable and sustainable alternative to carbon black in natural rubber foams

Polymer International, Volume 72, Issue 12, Page 1104-1111, December 2023., 2023
Natural rubber foams were prepared by replacing petroleum‐based carbon black (CB) with recycled silica. The total filler concentration was fixed (40 phr), while the CB/silica ratio was changed. The results showed that recycled silica is a suitable alternative to CB producing superior mechanical and thermal properties compared to commercial silica ...

Computational studies of rubber ozonation explain the effectiveness of 6PPD as an antidegradant and the mechanism of its quinone formation [PDF]

, 2022
The discovery that the commercial rubber antidegradant 6PPD reacts with ozone (\ce{O3}) to produce a highly toxic quinone (6PPDQ) spurred a significant research effort into non-toxic alternatives.

A Horizon Scan to Support Chemical Pollution–Related Policymaking for Sustainable and Climate‐Resilient Economies

Environmental Toxicology and Chemistry, Volume 42, Issue 6, Page 1212-1228, June 2023., 2023
A Delphi approach to horizon scan of emerging chemical pollution issues of concern shortlisted 15 priority topics spanning the broad themes of “green” chemicals, unregulated chemicals and emissions, susceptible populations, fibers and materials, and intersections with climate and artificial intelligence.
