Present State and Future Trends of Negative Ion Mass Spectrometry in Toxicology, Forensic and Envirs ago and earlier, no papers on anion MS were presented in the international meetings organized by Dr. Frigerio and his group in Italy. Last year at Riva del Garda, there was one (1), and this year there will be 4 or 5.

,Mass Spectrometric Characterization of Sydnocarb ? and its Major Metabolites in Rat,c doses do not cause euphoria or locomotor excitation. Studies concerning the pharmacokinetics of sydnocarb in rat have been carried out using sydnocarb labelled with .C at various positions (2, 3), but no report on metabolic fate of this drug has appeared in literature.

Urinary Metabolites from (2-Ethyl-2,3-Dihydro-5-Benzofuranyl) Acetic Acid, preliminarily restricted to acidic compounds in the reasonable assumption that the acidic function originally present in . could not be destroyed. In fact from an acidified urine chloroform extract of treated rats four compounds related to . (Fig. 1) could be separated by tlc.

The Determination of Blood Cyanide and Plasma Thiocyanate by Gas Chromatography-Mass Spectrometry,ormed cyanide (4). Methods for the analysis of these two species in body fluids are necessarily extremely sensitive and the existing techniques include colourimetry (4, 5), fluorimetry (6, 7) and gas chromatography (8–10).
