Enhanced photodegradation of 6PPD and formation of 6PPD-quinone in ice

Water Research
The widespread occurrence of 6PPD-quinone (6PPD-Q), a highly toxic transformation product of the tire-derived antioxidant 6PPD, poses serious threat to salmon fisheries. Here, we provide the first quantitative evaluation of 6PPD phototransformation in ice under UV irradiation, a condition directly relevant to salmon habitats.

A mini review on 6PPD quinone: A new threat to aquaculture and fisheries

Environmental Pollution
Numerous toxic substances are directly and indirectly discharged by humans into water bodies, causing distress to the organisms living on it. 6PPD, an amino antioxidant from tires reacts with ozone to form 6PPD-Q, which has garnered global attention due to its lethal nature to various organisms.

The Xenometabolome of Early-Life Stage Salmonids Exposed to 6PPD-Quinone

Environmental Science & Technology
N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q) is a ubiquitous transformation product (TP) derived from the rubber tire antioxidant N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and is acutely toxic to certain species of Salmonidae. Not all salmonids are sensitive to acute lethality caused by 6PPD-Q, with 6PPD-Q potency

Uptake, Metabolism, and Transcriptome Responses to 6PPD-Quinone in Germinating Ipomoea aquatica

Environmental Pollution
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), a transformation product of the widely used tire antioxidant 6PPD, has emerged as a ubiquitous environmental contaminant with potential risks to agroecosystems and food safety.

Earthworm intestine orchestrates dual host-microbiome detoxification of 6PPD-quinone

Journal of Hazardous Materials
The highly toxic tire-derived compound N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q) poses emerging environmental risks, yet its fate within soil invertebrates remains unclear. Here, we investigate the tissue distribution, elimination kinetics, biotransformation, and detoxification of 6PPD-Q in earthworms.

Evidence for the formation of 6PPD-quinone from antioxidant 6PPD by cytochrome P450

Journal of Hazardous Materials
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) as a rubber antioxidant has attracted global concern, since its ozone-oxidation product 6PPD-quinone (6PPDQ) was found to be the primary toxicant responsible for urban runoff mortality syndrome in coho salmon.

Mass Spectrometry Imaging Unveils the Metabolic Effect of 6PPD-Quinone in Exposed Mice

Environmental Science & Technology
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine quinone (6PPD-Q) has gained widespread attention as an emerging significant environmental contaminant, but its biochemical toxicity in mammals remains inadequately explored. In this study, the systemic toxicological effects of 6PPD-Q in mouse models exposed to both high and low doses were investigated.

Efficient catalytic degradation and detoxification of 6PPD-quinone by the multifunctional enzyme system of phanerochaete chrysosporium

Journal of Hazardous Materials
The widespread environmental presence and toxicity of N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-quinone, 6PPD-q), a rubber-derived pollutant, necessitates effective degradation strategies. This study demonstrates for the first time that Phanerochaete chrysosporium (P.

Acute toxicity testing of 6PPD‐quinone on the estuarine-dependent sport fish, Sciaenops ocellatus

Ecotoxicology
Recently, large-scale fish kills in the Pacific Northwest were linked to tire wear particles (TWPs) left on roadways, with the lethality attributed to 6PPD-quinone. which has a median lethal concentration of
