| pectenotoxin-2 seco acid, 7-epi-pectenotoxin-2 seco acid and pectenotoxin-2 in shellfish and plankton from portugal. | pectenotoxin-2 seco acid (ptx2sa) and 7-epi-pectenotoxin-2 seco acid (7-epi-ptx2sa) were found in portuguese shellfish both by fluorescence detection after adam derivatisation and, liquid chromatography coupled with mass spectrometry detection. two time-series both with blue mussel (mytilus edulis) and common cockle (cerastoderma edule) from aveiro lagoon illustrate how ptx2sa has a strong association with dinophysis acuta occurrence in the plankton, as well as dinophysis fortii. data so far exc ... | 2002 | 12076652 |
