An Urban Stormwater Contaminant Signature: Defining Priority Contaminants for Urban Stormwater Research

Water Environment Research, Volume 97, Issue 7, July 2025.
We identified a core suite of frequently detected contaminants in urban stormwater ponds using three complementary sampling methods. This urban stormwater contaminant signature (USCS) highlights cumulative exposures in pond ecosystems and supports more targeted monitoring of urban runoff.

Respiratory toxicity mechanism of 6PPD and 6PPD-quinone: An integrated study based on network toxicology and molecular docking

Ecotoxicology and Environmental Safety
The widespread distribution of environmental contaminants poses a significant threat to public health. N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) and its ozone-derivative, 6PPD-quinone (6PPD-Q), are emerging pollutants that propagate ...

Solar Light Activated Periodate for Degradation and Detoxification of 2 Highly Toxic 6PPD-Quinone at Environmental Levels [PDF]

Degradation and detoxication of highly toxic 6PPD-quinone remain great challenges due to its stable structure. Herein, we establish a solar-light-driven IO4- activation system for efficient degradation of 6PPD-quinone at environmental concentration ...

Acute Toxicity of the Tire Rubber-Derived Chemical 6PPD-quinone to Four Fishes of Commercial, Cultural, and Ecological Importance

, 2022
N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone (6PPD-quinone), a transformation product of the rubber tire antioxidant 6PPD, has recently been identified as the chemical responsible for urban runoff mortality syndrome in coho salmon, with a ...

6PPD and 6PPDQ embryonic exposure induced distinct developmental neurotoxicity in zebrafish

Ecotoxicology and Environmental Safety
The ecological risks of tire antioxidant 6PPD and its transformed metabolite 6PPD-quinone (6PPDQ) have received high attention. The present study evaluated the developmental neurotoxicity and potential mechanisms under 6PPD or 6PPDQ embryonic exposures ...

Integrated machine learning and experimental validation reveal S6K2 as a key target of 6PPD-quinone in bladder cancer

Ecotoxicology and Environmental Safety
Tire and Road Wear Particles (TRWP) are pervasive environmental contaminants, yet the molecular mechanisms linking their toxic derivative, 6PPD-quinone (6PPD-Q), to bladder cancer (BLCA) progression remain obscure.

Interaction between 6PPD/6PPD-Q and natural Fe-Mn nodules: Performance and mechanism of adsorption and oxidative transformation

Environment International
The widely used rubber antioxidant N-(1,3-Dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD) and its ozonated product, 6PPD-quinone (6PPD-Q), are highly toxic to aquatic life, yet understanding on their environmental behaviors is limited.
