Substituted diphenylamine antioxidants (SDPAs) and synthetic phenolic antioxidants (SPAs), widely used in rubber and consumer products, pose growing environmental concerns. This study evaluated the occurrence and release of 43 SDPAs and 4 SPAs in raw leachate and treated effluent from 18 municipal landfills across China. Results showed 17 SDPAs and 1 SPA ...

Synthetic antioxidants (SAs), a group of emerging contaminants, have attracted great attention recently due to their widespread environmental occurrence and potential toxicity. Yet, there is a knowledge gap regarding their occurrence and associated infant exposure in baby wipes, one of the most frequently used baby products. Here, we analyzed SAs-includin ...

Organophosphate esters (OPEs) have emerged as a global environmental and health concern due to their persistent, bioaccumulative, and toxic (PBT) properties. Recently, their precursors-organophosphite antioxidants (OPAs)-and transformation products, which may exhibit greater persistence and toxicity, have gained attention as critical contributors to OPE-r ...

Transformed from p-phenylenediamines (PPDs) antioxidant, PPD-derived quinones (PPD-Qs) have recently been recognized as emerging contaminants due to their potential negative impacts on the environment and human health. While there have been measurements of airborne PPD-Qs, the size distribution of PPD-Qs and the impact of particle size on PPD transformati ...

Polyphenols have a variety of phenolic hydroxyl and carbonyl functionalities that enable them to scavenge many oxidants, thereby preserving the human redox balance and preventing a number of oxidative stress-related chronic degenerative diseases. In our ongoing investigation of polyphenol-rich plants in search of novel molecules, we resumed the investigat ...

Background: The oxidative stress (OS) theory of disease stipulates that a chronic imbalance in the ratio of oxidants to antioxidants in the cellular environment leads to a variety of debilitating conditions, including type 2 diabetes, cardiovascular and liver diseases. Metabolites in the gut microbiome have been associated with increases in reactive oxyge ...
