Recent applications of mass spectrometry in the analysis of transformation products of emerging contaminants in PM2.5

open access: yesAnalytical Science Advances, Volume 4, Issue 3-4, Page 49-59, May 2023., 2023
Abstract Ambient pollution correlated to fine particulate matter (PM2.5) is a worldwide environmental issue as it is highly associated with human health and eco‐environmental safety. A significant part regarding the toxicity of PM2.5 is attributed to its bonded contaminants. Appreciable efforts have been performed to study the occurrence, exposure, and

Enzyme electrode for glucose oxidation using low‐solubility 4‐aminodiphenylamine derivatives as electron mediator

open access: yesElectrochemical Science Advances, Volume 2, Issue 4, August 2022., 2022
Enzyme electrode can be prepared using 4‐aminodiphenylamine derivatives (N,N’‐diphenyl‐p‐phenylenediamine; DPPD) as mediator molecules without covalent immobilization on the electrode. The proposed system was applied to carbon fabric to produce a glucose oxidation current of 7 mA/cm2, while the electrode catalytic activity was maintained at ...

Exposure to the Tire Rubber-Derived Contaminant 6PPD-Quinone Causes Mitochondrial Dysfunction In Vitro

open access: yes, 2022
N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone (6PPD-quinone), a rubber tire oxidation product found in road runoff, is highly and acutely toxic to selected salmonids including coho salmon, brook trout, and rainbow trout but not other fish ...

Environmental concentrations of tire rubber-derived 6PPD-quinone alter CNS function in zebrafish larvae [PDF]

open access: yes, 2023
N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine quinone (6PPD-quinone) is a degradation product of 6PPD, an antioxidant widely used in rubber tires. 6PPD-quinone enters aquatic ecosystems through urban stormwater runoff and has been identified as the ...

Review of 6PPD-quinone environmental occurrence, fate, and toxicity in stormwater

open access: yesEcocycles, 2023
The antioxidant N-(1,3-dimethylbutyl)-N?-phenyl-p-phenylenediamine (6PPD) is widely used to improve the durability of rubber. However, one of its transformation products, 6PPD-quinone (6PPD-Q), was recently found to be toxic. Herein, we aim to provide a comprehensive understanding of 6PPD-Q ecological and human-linked toxicity to facilitate the ...

Acute Toxicity of a Tire Rubber-Derived Chemical, 6PPD Quinone, to Freshwater Fish and Crustacean Species

open access: yes, 2021
N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone, also known as 6PPD quinone, was recently identified as a toxic chemical that causes acute mortality in coho salmon following exposure to urban runoff.

Enantioselectivity in Metabolism and Toxicity of 6PPD-Quinone in Salmonids

open access: yesEnvironmental Science & Technology
The toxicity of N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine quinone (6PPD-Q) in salmonids has been found to be sensitive to even minor structural changes on its alkyl side chain. Inspired by this, we herein isolated the enantiomers of 6PPD-Q and tested their in vitro metabolism and toxicity in rainbow trout (O.

6PPD-quinone disrupts the MARCHF2-EXOC7 ubiquitin axis to drive ferroptosis and redox imbalance in podocytes

open access: yesEcotoxicology and Environmental Safety
N-(1,3-dimethylbutyl)-N-phenyl-p-phenylenediamine quinone (6PPD-Q), a quinone derivative of the tire antioxidant 6-PPD, has exhibited toxic effects across a wide range of organisms.

Mixture toxicity of 6PPD-quinone and polystyrene nanoplastics in zebrafish

open access: yesEnvironmental Pollution
Plastic pollution, including micro- and nanoplastics, is a growing concern. Tyre-wear particles (TWPs) are the second largest source of microplastics in the ocean following abrasion of synthetic fibres. In addition to the particles themselves, TWPs contain many harmful chemicals, including 6PPD. This chemical reacts with atmospheric ozone and forms the
