Trace analysis of environmental matrices by large-volume injection and liquid chromatography-mass spectrometry

Creator:

Busetti, Francesco, Backe, Will J., Bendixen, Nina, Maier, Urs, Place, Benjamin, Giger, Walter, and Field, Jennifer A.

Abstract:

The time-honored convention of concentrating aqueous samples by solid-phase extraction (SPE) is being challenged by the increasingly wide spread use of large-volume injection (LVI) liquid chromatography-mass spectrometry (LC-MS) for the determination of traces of polar organic contaminants in environmental samples. Although different LVI approaches have been proposed over the last...

Accumulation and effects of 4-nonylphenol in chinook salmon fry and their estuarine amphipod prey

Creator:

Hecht, Scott A.

Abstract:

4-nonylphenol (NP), a surfactant degradation product, is an unregulated, ubiquitous aquatic contaminant and endocrine disruptor, for which aquatic life criteria are currently under development by U.S. EPA. The effects of NP on estuarine amphipods and chinook salmon fry were investigated, and this dissertation reports research into the impacts of NP...
