摘要

A method is proposed for the simultaneous determination of amnesic shellfish poisoning (ASP) toxin, diarrhetic shellfish poisoning (DSP) toxins, spirolides, azaspiracids (AZP), pectenotoxins (PTX), brevetoxins (PbTx), and gymnodimine. After extraction of all these toxins with one solvent only the crude extract is subjected directly to reversed-phase LC-MS with atmospheric-pressure ionization. The method was applied to bulk plankton samples obtained during a research cruise off the east coast of Scotland in May, 2000. Contamination of plankton samples from one spot with different toxins from a variety of groups was determined. [References: 34]
