Mutagenicity testing of diethylene glycol monobutyl ether.
The mutagenic potential of diethylene glycol monobutyl ether (diEGBE) was examined with a Tier I battery of in vitro assays followed by a Tier II in vivo Drosophila sex-linked recessive lethal assay. The in vitro battery consisted of: the Salmonella mutagenicity test, the L5178Y mouse lymphoma test, a cytogenetics assay using Chinese hamster ovary cells and the unscheduled DNA synthesis (UDS) a...
متن کاملSELECTIVE TRANSPORT AND EXTRACTION OF ALKALI METAL CATIONS (Na & K ) THROUGH CHLOROFORM LIQUID MEMBRANE BY DIETHYLENE GLYCOL MONOBUTYL ETHER AND DIETHYLENE GLYCOL DIBUTYL ETHER
A liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for K ion in transport while diethylene glycol dibutyl ether (1) was selective for Na over K . As an extractant, ligand 2 exhibited pronounced extraction selectivity for K over Na in comparison with ligand 1
متن کاملAn electrostatic autoresonant ion trap mass spectrometer.
A new method for ion extraction from an anharmonic electrostatic trap is introduced. Anharmonicity is a common feature of electrostatic traps which can be used for small scale spatial confinement of ions, and this feature is also necessary for autoresonant ion extraction. With the aid of ion trajectory simulations, novel autoresonant trap mass spectrometers (ART-MSs) have been designed based on...

Carbon emissions from tropical deforestation are expected to increase atmos...
متن کاملReproductive toxicology. Diethylene glycol monoethyl ether.
Background: In contrast to DNA-mediated transposable elements (TEs), retrotransposons, particularly non-long terminal repeat retrotransposons (non-LTRs), are generally considered to have a much lower propensity towards horizontal transfer. Detailed studies on site-specific nonLTR families have demonstrated strict vertical transmission. More studies are needed with nonsite-specific non-LTR famil...
