Abstract

Sixty nine chemicals that have high probability of chemical accidents are designated as the substances requiring preparedness for accidents and managed for public health protection under the Toxic Chemicals Control Act. When a chemical accident or chemical terror is occurred, the exact detection and analysis of the chemicals is rapidly required for acquiring the qualitative information. In this study, the substances requiring preparation for accidents were detected and analyzed to establish stage of detection and analytical method using portable GC/MS (Gas Chromatograph-Mass Spectrometer), portable FT-IR (Fourier Transform Infrared spectrometer) and portable XRD (X-Ray Diffractometer). Volatile organic chemicals and organic gases were analyzed by GC/MS and solids having crystal structure were analyzed by XRD. Organic, inorganic liquids and solids were analyzed by portable FT-IR. Therefore, twenty four chemicals were be analyzed by portable GC/MS and forty eight chemicals were be analyzed by portable FT-IR. Also eleven chemicals were be analyzed by portable XRD. Sixty nine chemicals were classified according to their physicochemical properties. As a result, an on-site library containing the spectra generated by the above mentioned portable analysis equipments was constructed for early detection and characterization of chemical agents.
