Occurrence, Ecological Risk, and Human Exposure of Rubber Additives and Transformation Products in Surface Waters of Kaifeng, China

Toxics
This study investigated rubber additives and relevant transformation products (RARTPs) in surface waters of Kaifeng, a city linking the Yellow River and Huaihe River basins. Seven of fifteen target analytes were detected in >10% of samples.

Urban pavements as sources and conduits of microbial, microplastic, and emerging contaminants in water systems: A critical review of mechanisms, pathways, and mitigation

H2Open Journal
Urban pavements act as reactive environmental interfaces, generating, retaining, and mobilizing pollutants, including microbial communities, microplastics, and emerging chemical contaminants. This critical review synthesizes 107 studies (2020–March 2026),

Synergistic influence of temperature and contamination by 6PPD-Q on the development of Arctic Char larvae: differential effects between populations from Lakes Geneva and Annecy

Freshwater ecosystems are experiencing significant biodiversity loss due to multiple anthropogenic stressors, including temperature fluctuations and chemical pollutants such as 6PPD-quinone (6PPD-Q), a toxic byproduct of tire wear.

Development and application of diffusive gradients in thin-films for in-situ monitoring of 6PPD-Quinone in urban waters

The occurrence and risk of N-(1,3-dimethylbutyl)-N '-phenyl-p-phenylenediamine-quinone (6PPD-Q), derived from the oxidation of the tire antidegradant 6PPD, has raised significant concern since it was found to cause acute mortality in coho salmon when ...

Nationwide distribution, transformation, and risks of p-Phenylenediamines and their quinone transformation products in Chinese agricultural soils

Environment International
p-Phenylenediamines (PPDs) are widely used as antioxidants in tire formulations and are released to the environment via tire wear, where they can be transformed into more toxic p-phenylenediamine-derived quinones (PPD-Qs).

Non-persistent environmental chemical mixture and gestational hypertension, blood pressure, and blood pressure trajectories during pregnancy

Environment International
Background: Gestational blood pressure (BP) is susceptible to exogenous exposures, including environmental chemicals. However, epidemiological evidence is lacking, particularly for the emerging contaminants. Methods: We quantified 31 urinary chemicals in

The impact of blue-green infrastructure on trace contaminants: A catchment-wide assessment

Water Research X
Blue-green infrastructure (BGI) reduce urban combined sewer overflows (CSOs) and stormwater outlets (SWOs). However, most conventional BGI are not designed to remove trace organic contaminants.
