In this study was analyzed substances that high contribute to odor strength degree which emitted from the painting, the plating, the casting, the rubber manufacturing, and the used oil refining facilities in Gwangju Hanam industrial complex. In order to this, we analyzed two types of nitrogen compounds, five types of sulfur compounds, thirteen types of the aldehyde, and ten types of volatile organic compounds discharged from an outlet for antipollution facilities. The results are as following high contribution rate sustances to odor strenth was ordered butylaldehyde (73.8%) ＞ acetaldehyde (17.7%) ＞ propionaldehyde (4.9%) at painting facilities. At plating facilities, it was ordered Acetaldehyde (59.0%) ＞ ammonia (19.1) ＞ hydrogen sulfide (13.1%). At casting facilities, it was ordered Hydrogen sulfide (65.9%) ＞ acetaldehyde (17.2%) ＞ sulfur dioxide(5.2%). At rubber manufacturing facilities, it was ordered i-valeraldehyde (35.0%) ＞ butylaldehyde (32.0%) ＞ n-valeraldehyde (13.3%) and at used oil refinery facilities, it was ordered Acetaldehyde (36.8%)＞ butylaldehyde (33.6%) ＞ sulfur dioxide (14.5%).

In this study, the emission characteristics of reduced sulfur compounds (RSC) including H₂S, CH₃SH, DMS and DMDS released via cooking were investigated. Cooking smoke samples were produced by two different cooking methods (fry and steam) and analyzed for direct comparison between three types of food (cabbage, clam and coffee bean). In general, a large quantity of RSC came out from fried foods relative to steamed foods. The conversion of RSC concentration to odor intensity (OI) showed OI values in the range of 2.54∼6.41 for fried foods and 1.23∼3.68 for steamed foods. The results of this study suggest that we need to develop and establish environmentally friendly cooking methods.

Investigation of the odor source is necessary to establish of the effective counter plan for reducing the odor emitted from the industrial complexes. This study was carried out to investigate the characteristics of the odor emitted from leather manufacturing plants, using three methods which are a direct sensory technique, an air dilution sensory test and a instrumental analysis. Total 7 samples were sampled at 3 points of three factories in this study. As a results of this study, while odor intensity of 7 samples ranges from 2 degree to 4 degree, dilution ration of olfactory test shows the range from 300 to 600. It was estimated that main malodorous compounds ordered hydrogen sulfide, methyl mercaptan, i-valeraldehyde.

We carried out basic study on the major odor substances from livestock waste treatment plant to design high efficiency offensive odor treatment facility. We choose Y and G-treatment plants and measured each samples from pre-treatment facility, water treatment facility, sludge treatment facility and offensive odor treatment facility. The odor was mainly produced from pre-treatment facility from above measurements. The concentration of hydrogen sulfide was very high as 1,200 ppm from impurity treatment facility. The concentration of hydrogen sulfide was detected as 100 ppm in waste water treatment facility(aeration facility and head) and 160∼252 ppm in sludgy treatment facility (retaining facility and scum tank). The offensive odor treatment facility was composed of washing tower using NaOCl as washing material and bio-filter. Efficiency of the offensive odor treatment facility on the hydrogen sulfide was 5∼33% and the efficiency on the ammonia was low except Y-treatment facility’s vortex mixer washing tower which is 98%. Reduction efficiency of hydrogen sulfide was increased from 14.7% to 96.3% by changing washing material, NaOH, at Y-treatment facility’s vortex mixer washing tower.

In this study, A method for confirming the putrefaction point of apples by using odor variation as applied in apple storage. The samples were obtained from apple storage at Chuncheon shi Dongnae-myeon using by lung sampler. The complex odor was separated by GC/O and individual odors were then analyzed. In the apple storage, the varieties and number of apples vary based on cultivarsand sales volume of apples. Thus, using an emission chamber in the apple storage is difficult. The odor value of the emission chamber and apple storage is denoted by standardizing the sizes and number of apples. The variations in the ratios of aroma value and off-odor value were investigated. The ratio of the aroma value and off-odor value in the emission chamber increased. However, the apple storage values were applied on the number of apples, thus the values alternately increased and decreased in most cases. If the internal change of apple started, it is ratio of aroma value and off-odor value is cloese to zero. and If the External putrefaction on the apple surface is confirmed, the log value becomes larger than 0.5. Complete putrefaction in the stored apples, the log value close to 1.5. We therefore confirmed that this noninvasive method using odor variation can apply to monitoring the quality of apples in storage.

This study was conducted to induce the effective counterplan of odor management in the Sihwa industrial complex(SIC) utilizing to CALPUFF model with sensory odor. The CALPUFF model was applied to simulate a sensory odor, and was evaluated for odor applicability and the distribution status of odor in SIC was predicted. The simulated concentration showed lower than observed concentration but the prediction of odor was so excellent. The simulation result of CALPUFF model for SIC showed that annual mean odor unit was 5∼7 OU/㎥ (min. 3 OU/㎥, max. 25 OU/㎥). The annual mean odor unit in residential area was not high as 1∼3 OU/㎥ but was predicted to be affected by the weather status in the industrial complex. The odor emission sources of high concentration were distributed in the seashore. Therefore the management of the high concentration sources will be further demanded.
