摘要：

Arsenic species that do not form hydrides have been recently put in evidence in coastal seawater. This paper describes the procedures used in the first attempts to concentrate, purify and identify these forms as well as the difficulties that make this identification problematic. The rationale behind a new scheme under investigation based on solvent extraction/high-performance liquid chromatography/dynamic-flow-fast-atom-bombardment mass spectrometry is presented. Some alternatives that seem promising for the future are indicated.
