This study has intended to analyze the impact of odor perception of residents, who currently live in Ochang industrial complex, on their subjective odor sensitiveness. In addition to the relationship between the perception and the sensitiveness, odor acceptance was considered as moderating variable in a research model. Korean governments has experienced even great and small civil complaints regarding bad smells throughout the country especially around the industrial complex. The residential areas are getting much closer to industrial complex due to major cities’ expansion. The closer cities are to industrial areas, the bigger the conflicts are growing due to the odor. According to the research results, it was proven that residents’ concerns on an bad image due to odor, their perception on an administrative agency’s responsibilities and economical values of their living places have a significant effect on the odor sensitiveness. Moreover, odor acceptance perceived by them has a negative moderating effect between odor perception and odor sensitiveness. Based on such results, implications and suggestions are included in the research to support the research objectives.

This study attempts to investigate the impact of pollution by VOCs at schools located around Shihwa national industrial complex. Schools around the Shihwa national industrial complex were divided into two categories based on location, with five schools located near the industrial complex and five schools located near housing development. Samples of the indoor air and the outdoor air were collected from each classified school and analyzed to evaluate the impact of the industrial complex on each school through a comparison and to find the correlation between them. In combination with this, this study attempted to conduct comparative evaluations of the schools in which there might be relatively higher indoor air pollution since new construction and extension or remodelling had recently been carried out with other schools. The samples collected from 10 places in total were analyzed, using GC/MS. TVOCs, and individual component of VOCs, were detected in the schools near shihwa national industrial complex at higher levels than in the schools nearby housing development. TVOCs were detected at the schools in the industrial complex st levels of 166.5 μg/m3, that is, about 1.5 times higher than the level detected at the schools outside the industrial complex. TVOCs were found in the indoor air of the schools that had been extended or remodelled less than 3 years ago at levels of 188.8 μg/m3, while in schools where more than 3 years had passed since extention or remodelling they were found at levels of 97.5 μg/m3, meaning they were about 1.9 times higher in schools in the first 3 years.

The purpose of this study was to investigate the odor arising from the Cheong-ju industrial complex area for odor materials confirmation, and to predict the impact of the odor in the residential area using the CALPUFF Model. Among the odor causing substances in the area with a rising number of collective complaints due to odor, methyl sulfide, acetaldehyde, propionaldehyde, n-buthylaldehyde, n-valeraldehyde and styrene were detected. Odor causing substances detected in the area surrounding the industrial complex include ammonia, hydrogen sulfide, n-buthylaldehyde, toluene, xylene, benzene and styrene. Using the CALPUFF Model, it was predicted that 1hr average was 3.981~7.553 OU/m3 and 24hr average was 1.753~2.359 OU/m3. In terms of odor intensity, the predicted 1hr average was 0.6~0.9 and the 24hr average was 0.2~0.4.

The objectives of this study were to characterize the factors affecting exposure to the VOCs and NO2 in the vicinity of Gwangyang industrial complex. The VOCs and NO2 levels were measured for residents of an exposure group (industrial area within 5 km) and a control group (15 km farther), respectively using the VOCs and NO2 filter badge as a passive sampler from August to September 2006. The means of indoor, outdoor, workplace and personal exposure levels of benzene were 1.10 ppb, 0.94 ppb, 1.85 ppb and 2.35 ppb respectively in the exposure group. The means regarding toluene for the exposure group were 9.29 ppb indoor, 8.09 ppb outdoor, 14.5 ppb workplace, 14.2 ppb personal exposure. The means regarding ethylbenzene were 4.96 ppb(indoor), 4.45 ppb(outdoor), 6.84 ppb (workplace), 6.10 ppb(personal exposure), and the means regarding xylene were 0.10 ppb(indoor, outdoor), 0.18 ppb(workplace) 0.17 ppb(personal exposure). The means for the indoor, outdoor, workplace and personal exposure level of NO2 were 18.40 ppb, 18.51 ppb, 18.59 ppb, 18.80 ppb respectively in the exposure group. Correlations between personal exposures and workplace concentrations of individual VOCs and NO2 exposures, and each of the microenvironment was statistically significant.

This study tried to survey air quality inside and outside the schools where are located in about 5km of industrial complex targeting aldehyde, PM10, PM2.5. Also, the aim was also to examine both a change in indoor air after 3 years and within 3 years of addition and improvement, and a change according to season. It collected specimens at totally 20 places. Aldehyde was analyzed through HPLC. PM10 and PM2.5 were measured by using Met One 831. Formaldehyde and Acetaldehyde were detected with 42.1 μg/m3 and 5.7 μg/m3 at the school where is located inside 5km of the industrial complex, and were detected with 55.0 μg/m3 and 6.8 μg/m3 at the school where is located outside 5 km. This could be confirmed to have been detected more highly in the indoor air than the outdoor air regardless of the distance from the industrial complex. Most substances were indicated to be higher by about 150% in the indoor air within 3 years than the indoor air following 3 years of addition and improvement. However, PM10 and PM2.5 were measured with 32.6 μg/m3 and 14.9 μg/m3 after 3 years and were gauged with 22.4 μg/m3 and 14.2 μg/m3 within 3 years. Seeing a seasonal change, Formaldehyde and Propionaldehyde were detected with 5.5 μg/m3 and 1.0 μg/m3 in spring, 7.7 μg/m3 and 1.6 μg/m3 in summer, and 8.3 μg/m3 and 1.9 μg/m3 in autumn. This could be confirmed the tendency of growing according to season.

This study was conducted to find an odor reducible solution in Hwayang agricultural industrial complex. Civilcomplaints have lasted because of odor caused by recycled plastic producers. In order to understand the emissioncharacteristic and concentration of key odor components, we investigated the complex odor and 17 odorcompounds at 3 sites of five chemical facilities from march to october 2013. The results of complex odor showed8~12 at a boundary of 5 facilities. The results of complex odor showed 6694, 3000, 1442 at an emission (stack)of 3 facilities, which exceeded the emission standard. The highest compound and its concentration of each sitewas different because each facility has different processes and use different raw materials. We suggested thesuitable prevention facility for each company to reduce odor. We analyzed the odor contribution with the emission(stack) point of S, I, B and the inside point of W, J. S plant was Acetaldehyde (45%), I plant was Trimethylamine(32%), B plant was Styrene (35%), W plant was Hydrogen sulfide (42%), J plant was Hydrogen sulfide(41%).An objective of study is odor management area and will apply odor strict emission standards. A suitable preventionfacility should be operated efficiently based on survey data to reduce odor.

The purpose of this research is to clarify the valuable industrial heritages of rice mill industry complex remained in Incheon. In order to clarify the formation of integrated historical setting of rice mill industry of Incheon, we analyzed the old map of Incheon’s old Jemulpo area and data on address, locations and happenings surrounding rice mill factories and relevant facilities. From here, we could find out the 4 representative rice mill industry area of integrated historical setting and 2 other supporting service area for rice mill industry in old city center of Incheon. Specifically, we could figure out the incremental stages to establish the rice mill industry in Incheon. In the first stage, the rice mill factories were established near foreign settlement area where trading offices and warehouses were equipped. And the second stage reflect the needs of expanding area for Japanese capitalism with the new landfill area. In the final stage, Korean rice mill owners established the korean laborers community near Korean residential area. This formation of integrated historical setting reflecting Incheon’s rice mill industry is the identical industrial heritages and urban structures to show the tension and conflict between Japanese and Korean laborers’ life in the Japanese Colonial Period.

In this study, odors in N industrial complex in Incheon city were measured by using air dilution olfactory method, odor sensor and instrumental analysis method. Three industry categories which are plating industry, equipment manufacturing industry and petrochemical manufacturing industry were classified and the correlation of data was evaluated based on the measurement result. The correlation coefficient between the air dilution olfactory method and the odor sensor device utilizing method in 69 points was 0.562. The correlation coefficients in the classified industry categories were observed 0.889 in the plating industry, 0.723 in the equipment manufacturing industry and 0.832 in the petrochemicals manufacturing industry. It shows that when the correlation coefficient is over 0.75, they have a strong correlation. In this result, we could identify the ease of availability of the correlation using industry classification.

This study investigated impact of odors from industrial areas using the FIDOL concept. The studied region was the Seobu industrial complex in Korea. The USEPA dispersion model, AERMOD, was used to calculate odor concentration. The results show that the size of the impact areas of lower regulation compliance frequency is smaller than that of the areas of higher regulation compliance frequency. The results also showed that increasing the concentration of odor unit (OU) decreased the size of the impact area and the maximum impact distance. Calculated odor impact area, using Massachusetts (USA) regulations, had the smallest impact area among selected locations such as Massachusetts (USA), New Zealand, Denmark, and the Netherlands. Denmark’s regulations had the largest impact area.

It was investigated the state information for the atmospheric conditions around Dang-jin industrial complex in Chungnam area may be polluted by the constructing steel industrial complex. It is aimed at characterization of the fine particulate matter and other air pollutants involved in it. Samples were collected two sites for monitoring point representing steel industrial complex and one site which is placed a remote and secluded from this industrial complex, and the concentration of PM10, heavy metals, and ion components were analyzed. As a results, PM10 average concentration was 64.6㎍/㎥ for the adjacent site before Hyundai Steel Company, 70.5㎍/㎥ in Bugok immigration settlement complex, and 56.5㎍/㎥ for Jeonggok-ri contrastive point. The distribution of heavy metals was detected as very low level for all sampling points. According to the result of statistical evaluation for the heavy metal analysis, variation range of Cu, Mn, Ca, Fe, and Mg were significant higher than others. Also, the seasonal concentration change trend of heavy metals was remarkable strong in spring and low in summer because of instable meteorological phenomena such as yellow dust happened in spring. Monthly changing pattern of a sulphate ion has kept unusually high level for summer period different other components. Relationship among PM10, heavy metal, and ion component were analyzed that high positive correlation coefficient for PM10 between Fe, Mn, Pb, Ca, Mg, Cd, Al in order and PM10 between NO3-, Cl- successively. Accordingly, it is suggested that a present atmospheric conditions of the surrounding area of Dang-jin steel industrial complex is considered to be good level. Although air pollutants in emissions from their complex were below the existing emission limit, it is regarded that the systematic and continuous research is needed to preserve clean air through atmospheric monitoring, source tracing research, and citizen's surveillance for the fine particulate matter.

This study presents residential indoor and outdoor exposure concentrations distributions of volatile organic compounds (VOCs, benzene, toluene, xylene) and nitrogen dioxide (NO₂) in industrial area (case) and agricultural area (control) during 5 days. Concentrations of VOCs and NO₂ were measured with passive samplers in residential indoor and outdoor. Most of benzene, toluene and NO₂ mean concentrations in case area were higher than those in control area. Considering the indoor and outdoor ratios (I/O) were higher than 1, the residence might be have the sources of indoor air pollutants such as smoking and using of gas range. Residential indoor concentrations of benzene, toluene, and NO₂ with indoor smokers were higher than those and without indoor smokers. In conclusion, it is suggested that personal exposures to air pollutants might be affected by indoor sources as well as outdoor pollutants emitted from industrial complex, and indoor air quality and outdoor air quality should be simultaneously considered to reduce the personal exposure to air pollutants.

울산공단지역과 지리산지역에서 소나무림의 강우로부터 산림내 유입되는 수간류, 수관통과우, 임외우의 이온성분을 조사하여 그 특성을 분석하였다. 울산공단지역에서는 pH가 지리산지역에 비해 수간류, 수관 통과우, 임외우 모두 낮아 대기오염의 영향으로 추측할 수 있었다. EC는 수간류, 수관통과우, 임외우 모 두 울산공단지역이 높았으며, 수간류와 수관통과우에서는 양지역이 2배 정도 차이가 있었다. 이온성분은 울산공단지역에서 대체적으로 높았으며, 수간류에서 지역차가 2배 이상 나타났으며, 특히 Ca2+, Mg2+ 이 온의 농도가 지역간 차이가 높게 나타났다. 음이온 성분은 두 지역 모두 SO4 2->NO3 ->Cl- 순으로 나타났 으며, 지역간 차이가 가장 큰 이온은 SO4 2-으로써 수간류에서 토양으로 유입되어 토양의 산성화를 초래할 뿐만 아니라 산림생태계 전반에 영향을 미칠 수 있다.

In this paper the lifetime risk assessment of exposure to airborne volatile organic compounds (VOCs) in environmental atmosphere was carried out in one of the Korean industrial city, Gumi based on their measurements of VOCs at five representative outdoor monitoring sites. According to this study toluene, trichloroethylene, and dichloromethane are three main VOCs in Gumi. The carcinogenic risks 5the carcinogenic VOC are greater than the benchmark concentration (1.0E-6) in all five designated sites. Particularly, the Lifetime Cancer Risk in industrial complex 1 and 2 reached 9.64E-5 and 1.32E-4, respectively, both of which are far higher than the benchmark risks. The components of predominant risk in industrial areas are found as chloroform, benzene and trichloroethylene, while those of other sites are benzene and chloroform. It was estimated that the contributions of those componentsto cancer risk are not less than 90%. For non carcinogenic VOCs, the total hazard indices in 5 monitored sites are less than 1. The hazard index in industry complex No. 2 recorded the highest among 5 sites up to 0.663 due to the dominant contribution of 1, 2-dichloropropane by up to 50% (0.335). Based on this analysis, effective emission reduction for chloroform, benzene, trichloroethylene, and 1,2-dichloropropane will rapidly I the cancer risks and hazard indices in Gumi.

The objectives of this study were to analyze the characteristics of odor in the major facilities of a fishery industrial complex using the air dilution olfactory method and the instrumental analysis method. The results indicate that although the limit of dilution to threshold (D/T) ratio in the major facilities is not regulated by the Odor Emission Standard, the mean (D/T) ratio over than 3,000 which is higher than the limit in the outlet of industrial area 3 times was found at three sampling sites. In the case of the concentration of the malodorous compounds, ammonia concentration is higher than any other odor compounds. The methyl mercaptan, n-Butyric acid and hydrogen sulfide as the main pollutants are confirmed by the odor quotient (OQ). In our study, it is showed a moderately good correlation between the (D/T) ratio and the sum of OQ. By this result, we can estimate the odor characteristics and evaluate the potential impact of each odor compound. In addition, we consider that it will affect the people"s normal life and even cause for complaint around the boundary area by the diffusion of odor.

The government separated and established the industrial safety and health law from the Labor Standard law since 1981 to promote the labor's working environment and to improve the conditions of laborers. The government made a lot of effort to discharge the industrial safety and health law by continuous revision of the law thereafter. it is, however, difficult to establish clear-cut lines of authority and responsibility due to the fact that the substantial application of the industrial safety and health law is adapted by enterprise's autonomous management. There are frequent industrial disasters on the small and medium enterprises which have financial difficulty and it means this causes much more social cost. Finally, for the improvement of laborer's safety, health and working environment in the small and medium enterprises we need to raise the effectiveness of the industrial safety and health law through enhancing a government-office's administration and surveillance with the changing mind of a business proprietor. On this paper, we research on the actual condition of the administration, inspection and regulation of safety and health by means of the industrial safety and health law. Thereafter we analyze how much the Korea Occupational Safety & Health Agency and vicarious businesses of safety & health management help. we used the survey method to gather data from 380 laborers directly and analysed the data by SPSS v17.0.

To evaluate environment of farm lands using indicator insects and evaluation indices, the insect abundance of which is one of the major criteria for the evaluation of agricultural environment of farm land in urban areas and industrial complex, three sites (Ansan, Daesan, Suncheon) were designated and monitored from 2004 to 2006. The flora of agricultural land was more than urban areas and industrial complex of that in three sites. Soil, water and air pollution of urban areas and industrial complex were more serious than those of agricultural land in three sites. Overall population of insects were high from June to August in the surveyed three sites. Collected insects in agricultural land were 12 order, 106 family and 166 species, those in urban areas were 11 order, 102 family and 148 species, and in industrial complex were 11 order, 100 family and 152 species. Species and population belonging to Coleoptera was dominant in the surveyed sites. The insect diversity indices of farm land were 2.36 in agricultural land, 1.92 urban areas and industrial complex. And agricultural environment of agricultural land was good, urban areas was common and industrial complex was poor. Based on the major criteria of evaluation items, the criteria were selected as diversity index over 2.1, insect indicator Pheropsophus javanus in agricultural land, diversity index 1.5-2.0, insect indicator Nephotettix cincticeps in urban areas, diversity index below 1.5, insect indicator Pagria signata in industrial complex.

  The most of national industrial complex were developed and supplied not according to the requirements of enterprise but the needs of the government. And it leads to current serious out of balance in demand and supply of industrial complex. Buckpyoung in

The emission concentrations of VOC and various odorous compounds were measured from different indoor process units located in 19 companies at the Ban Wall industrial complex from Jun. 2004 to Jan. 2005. The purpose of this study was to investigate the indoor pollution levels of various industrial facilities with respect to bothmalodorous compounds and volatile organic compounds (VOC). We also intended to build the database under the conditions affected by various anthropogenic processes with an aid of a statistical treatment. The three samplingmethods and five analytical techniques were applied tomeasure the sum of up to 32 individual compounds. According to this study, we were able to identify the importance ofmajormalodor compounds which include carbonyl compounds, reduced sulfur compounds, ammonia and trimethylamine. On the other hand, relative contribution of VOC as sources ofmalodor was ofminor significance except such compound as toluene. The overall results of this study thus indicate that the concentration levels of VOC in themanufacturing facilities are high enough to affect indoor laboring conditions.
