DOI: 10.1016/j.chemosphere.2018.07.146

Abstract: While flame retardant Dechlorane Plus (DP) and its dechlorinated analogs have been frequently detected in wildlife, knowledge is limited on their bioaccumulation and maternal transfer in amphibians. In the present study, the occurrence of syn-… read more here.

DOI: 10.1016/j.ijms.2019.05.014

Abstract: Abstract Metabolomics strongly relies on liquid chromatography hyphenated to tandem mass spectrometry (LC-MS/MS) for the separation and identification of metabolites. Retention times and fragmentation mass spectra are used as identification parameters. A complementary approach is… read more here.

DOI: 10.1021/acs.est.2c01287

Abstract: Sodium p-perfluorous nonenoxybenzenesulfonate (OBS), a novel alternative to perfluorooctane sulfonic acid (PFOS), has been widely used in various fields in China and has certain toxic effects similar to PFOS. This study monitored OBS and 15… read more here.

DOI: 10.1021/acs.est.2c04501

Abstract: Electrochemical fluorination manufacture of perfluorooctane sulfonic acid (PFOS), one of the most studied per- and polyfluoroalkyl substances, produces mixtures of linear and branched isomers, but little is known about human exposure to linear or branched… read more here.

DOI: 10.1039/d2cc05548a

Abstract: We report bistable indole-containing hemithioindigos (HTIs) with one-way quantitative photoswitching properties. Supported by state-averaged CASPT2/CASSCF calculations, we propose a mechanism for the observed one-way photoswitching that involves an isomer-specific excited state intramolecular proton transfer (ESIPT).… read more here.
