The antioxidant 6-PPD has been widely used to prevent cracking and thermal oxidative
degradation and to extend the service life of tire rubber. 6-PPD quinone (6-PPDQ) is formed …

To enhance tire durability, the antioxidant N-(1, 3-dimethylbutyl)-N′-phenyl-p-
phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone …

The huge consumption of the tire rubber antioxidant N-(1, 3-dimethylbutyl)-N′-phenyl-p-
phenylenediamine (6PPD) has resulted in pervasive contamination in aquatic environments …

The potential risk of N-(1, 3-dimethylbutyl)-N′-phenyl-p-phenylenediamine quinone (6PPD-
Q) to soil organisms remains poorly understood. Here we showed that 6PPD-Q pollution …

The aquatic ecological risks posed by the surface-active components of tire wear particles
(TWPs) are not fully understood. This study aimed to determine the acute (24 h exposure) …

Tire wear particles (TWPs) have been recognized as one of the major sources of
microplastics (MPs), however, effects of initial properties and photochemical behavior of …

Tire wear particles (TWPs) have caused increasing concerns due to their detrimental effects
on the soil ecosystem. However, the role of weathering in altering the toxicity of TWP to soil …

Abstract N-(1, 3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) and its derivative
6PPDQ have been detected in various environmental media, with harmful consequences for …

Abstract N-(1, 3-dimethylbutyl)-N′-phenyl-p-phenylenediamine quinone (6PPD-Q) is a
quinone derivative of a common tire additive 6PPD, whose occurrence has been widely …

Road tunnels play a crucial role in modern road networks, in both urban and non-urban
areas, and necessitate frequent cleaning and washing due to the harsh tunnel environment …
