Determination of chlorophenols in sediment using ultrasonic solvent extraction followed by solid-phase extraction, derivatization, and GC-MS analysis
A method for determination of chlorophenols (CPs) in sediments was developed using ultrasonic solvent extraction followed by solid-phase extraction, derivatization, and gas chromatography–mass spectrometry (GC-MS) analysis. Some effective operational details and parameters on mixing of samples and extraction solvent, adsorption loss, and extraction cycles of the derivatives were studied and ...

Environmental fate of three novel brominated flame retardants in aquatic mesocosms
Currently, little is known about the environmental fate and persistence of novel brominated flame retardants (NBFRs). The recent detection of NBFRs in sediment cores and air samples provides insight into their persistence and potential for transport. Limited numbers of laboratory studies have examined the fate and behavior of these compounds, but field‐based fate studies have been especially ...

Determination of PBDEs in Sediment Samples using the SpeedExtractor E-914
Polybrominated diphenyl ethers (PBDEs) are flame retardants used in a myriad of applications and are monitored worldwide because of health concerns. In this application, PBDE congeners were extracted from two sediment samples (certified sample and sediment core from Lake Maggiore) according to EPA method 3545A using the SpeedExtractor E-914 and determined by GC-MS/GC-ECD. The results were ...
