Acute Toxicity Testing of Pink Salmon (Oncorhynchus gorbuscha) with the Tire Rubber–Derived Chemical 6PPD-Quinone [PDF]

Environmental Toxicology and Chemistry
N‐(1,3‐dimethylbutyl)‐N′‐phenyl‐p‐phenylenediamine‐quinone (6PPD‐quinone) is a widespread contaminant of emerging concern resulting from oxidation of 6PPD, which is an antidegradant substance added to tires.

Exploring the toxicity of the new emerging toxicant 6PPD-Quinone to environmental microorganisms.

, 2022
This study examines the toxicity of the newly discovered molecule 6PPD-Quinone (6PPD-Q) to selected environmental microorganisms. After decades of intense research, this molecule, derived from a very common antioxidant (6PPD) used as a car tyre protector, has recently been identified as the main cause of the death of Coho salmon in the north-western ...

6PPD-Quinone: Revised Toxicity Assessment and Quantification with a Commercial Standard

Environmental Science & Technology Letters, 2022
Stormwater exposure can cause acute mortality of coho salmon (Oncorhynchus kisutch), and 6PPD-quinone (6PPD-Q) was identified as the primary causal toxicant.

Toxicity of 6PPD-quinone to four freshwater invertebrate species

Environmental Pollution, 2023
The antioxidant N-(1,3-Dimethylbutyl)-N'-phenyl-p- phenylenediamine (6PPD) is used to protect the rubber in tires from oxidation, which extends the life of the tire. When oxidized, 6PPD is transformed into 6PPD-quinone (6PPDQ). 6PPDQ, along with other tire ingredients, can enter aquatic ecosystems through the transport of tire wear particles in runoff ...

Acute Toxicity of 6PPD-Quinone to Early Life Stage Juvenile Chinook (Oncorhynchus tshawytscha) and Coho (Oncorhynchus kisutch) Salmon

Environmental Toxicology and Chemistry, 2023
Abstract The breakdown product of the rubber tire antioxidant N‐(1,3‐dimethylbutyl)‐N'‐phenyl‐p‐phenylenediamine‐quinone (6PPD)‐6‐PPD‐quinone has been strongly implicated in toxic injury and death in coho salmon (Oncorhynchus kisutch) in urban waterways.

First Insights into 6ppd Quinone Formation from 6ppd Photodegradation in Water Environment

Journal of Hazardous Materials, 2023
p-Phenylenediamines (PPDs), an important type of rubber antioxidants, have received little study on their environmental fate, particularly for their vital photodegradation process in water environment. Accordingly, N-(1,3-dimethylbutyl)-N'-phenyl-1,4-phenylenediamine (6PPD), as a representative of PPDs, was investigated experimentally and theoretically

A nation-wide study for the occurrence of PPD antioxidants and 6PPD-quinone in road dusts of China

Science of The Total Environment, 2023
N,N'-substituted p-phenylenediamines (PPDs) are widely used antioxidants in rubber tires, which could be released and accumulated in road dusts with rubber tires wear. As ozonation product of N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD), 6PPD-quinone (6PPD-Q) exhibited higher toxicity to coho salmon. However, studies on their environmental

Chemical characteristics, leaching, and stability of the ubiquitous tire rubber-derived toxicant 6PPD-quinone

Environmental Science: Processes & Impacts, 2023
We here report chemical characteristics relevant to the fate and transport of the recently discovered environmental toxicant 6PPD-quinone (2-((4-methylpentan-2-yl)amino)-5-(phenylamino)cyclohexa-2,5-diene-1,4-dione or “6PPDQ”).
