Development of high-resolution separatory techniques and mass spectrometric methods for the verification of saxitoxin and tetrodotoxin in water and soil / interim report prepared for Paul A. D'Agostino... : DR52-4/11-1991E-PDF

"Nature produces many compounds that are highly toxic to humans. Among the most toxic are certain metabolites produced by marine organisms; these include saxitoxin (STX), a member of a related family of compounds responsible for paralytic shellfish poisoning (PSP, the "red-tide" shellfish poisoning), and tetrodotoxin (TTX), the puffer fish toxin. These toxins have been recognized by the UN as potential chemical warfare agents. It is important therefore to have available analytical methods for verification procedures with respect to chemical warfare controls agreements. The extremely high toxicity of these marine toxins implies that such analytical methods must be capable of detecting, identifying, and if possible quantifying, the target compounds present at trace levels in complex matrices. [...] The present document thus represents an interim report on work done at IMB on instrumental techniques for trace analysis of these highly polar, thermally labile toxins"--page 1.
