 note = {application/pdf, Formic acid and acetic acid were measured in Yokohama City using the automatic analyzing system with GC/MS-SIM. The operation was continued several months without a trouble. In this period, the average concentrations of formic acid and acetic acid were 4. 38ppb and 2.21ppb, respectively higher concentrations of these acids were observed in day time and in fine weather. It was confirmed that they were generated in large amounts by photochemical reactions in the atmosphere. Concerning the variations of concentrations in a photochemical smog day, formic acid and acetic acid concentrations were found to rise to 8～11 times, compared with that of benzene which was little subject to decomposition. This showed that the acids were formed from any components, especially from aromatics. Then, this new analytical system was seemed to be effective to explore the poisonous substances in the air.},
