Abstract
|
|
|
|
Diarrhetic shellfish poisoning toxins were investigated by liquid chromatography-electrospray ionization mass spectrometry (LC-MS/MS). Okadaic acid (OA), Dinophysistoxin-1 (DTX1), Pectonotoxin2, (PTX2) and Yessotoxin (YTX) in bivalves were quantified. OA were found in four samples; mussel Mytilus edulis (0.001 μg/g), Oyster Crassostrea gigas (0.004 and 0.001 μg/g) and manila clam Ruditapes philippinarum (0.001 μg/g). DTX1, PTX2, and YTX were not detected from all of the samples examined.
