Photodecomposition and Bioconcentration of a Bisphenol A Metabolite in Medaka, Oryzias latipes [PDF]

, 2004
Exposure experiments in medaka and photodecomposition tests were performed using a metabolite of bisphenol A [4-methyl-2,4-bis(p-hydroxyphenyl)-pent-1-ene; MBP], the solubility limit of which is 42 mg/l of water.

Atomically Dispersed Fe‐Modified SnS for Sn‐Centered Peroxymonosulfate Activation Toward Acetaminophen Degradation

Advanced Science, EarlyView.
Atomically dispersed Fe regulates the local electronic environment and surface properties of SnS, while PMS preferentially coordinates to Sn through Sn–O interaction. Fe incorporation further enhances the Sn–OPMS interfacial interaction, facilitating Sn‐centered PMS activation and the generation of SO4•−/•OH for APAP degradation, thereby clarifying the
