Abstract

Lipophilic phycotoxins were measured by tandem mass spectrometry coupled to liquid chromatography (LC-MS/MS) in size-fractionated plankton samples taken at five stations in Arica Bay, northern Chile in the southern summer 2007/2008. Pectenotoxins-2 (PTX-2), -11 (PTX-11), -2 seco acid (PTX-2sa) and yessotoxin (YTX) were identified by comparison of retention times and collision-induced mass spectra of certified standards and field sample extracts. This is the first report of PTXs and YTX from planktonic samples in Chilean coastal waters. © 2009 Elsevier Ltd. All rights reserved.
