On the planning for the systematic management and control of the air pollution display methods were used to evaluate the spatial pollutant concentration status.
This study were conducted to investigate the practical using of Geographic Information System(GIS) technology on the air pollution control and management which were computer-based systems that were used to store and manipulate geographic information in the macro city. In this study 137 samples were corrected by passive samplers and analysed by GC/MSD for 16 VOCs in Seoul (25 distincts) distributed by TM-coordinate(2㎞×2㎞), and finally displayed by Arcview program(version 3.2, ESRI Inc, U.S.A) for windows. The concentration of benzene and toluene showed high level distribution in whole area of Seoul and distribution of butylbenzen, trichroloetylene, stylene showed high level in whole area of Seoul except a few distincts and the distribution of isopropylbenzene, 1,2-dichroloethane showed higher level in core area than that of Kangnam and Kangbuk area. In conclusion, products of this study of using GIS technology apply on the spatial distribution of VOCs concentration was very effective than that of other methods(e.g., contouring concentration method, pie or column chart, graduated symbols), especially in mapping and symbolization of pollution status evaluation.
