In this study, we measured volatile organic compounds in Gimhae city, South Korea. We selected twenty site and measured volatile organic compounds in ambient air by passive sampler when at sampling intervals of two month from April to December 2005. Passive sampler was exposed for fifteen day in ambient air. And samples were analyzed by GC/FID for volatile organic compounds. The results of each measured functional zone, mean concentration of each compound measured were generally higher the industrial complex area and traffic pollution area than residental area. Each area showed similar pattern for the observation period. concentration of measured each compound were the following order: winter > fall > spring > summer.
