본 연구에서는 스모그 챔버의 구성 및 국내외 연구 동향, 국내에 설치된 스모그 챔버의 특성을 살펴보았다. 스모그 챔버는 온도, 습도, 풍속 등이 시시각각으로 변화하는 열린 시스템에서 확인하기 어려운 초미세먼지의 생성 및 변화 과정을 연구하기 위한 목적으로 제작된 구조물이다. 스모그 챔버는 닫힌 시스템으로 구성되어 있으며, 챔버를 구성하는 반응벽, 하우징, 광원 등의 조건에 따라 다양한 연구를 수행할 수 있다. 선행연구에서는 주로 SOA의 생성 및 변화에 중점을 두고 수행되었음을 확인하였다. 이를 바탕으로, 국내에서 제작 설치된 스모그 챔버는 크기를 제외한 반응벽, 하우징, 광원 등이 선행연구를 통해 도출된 최적의 구성으로 이루어진 것을 확인하였다. 또한 국내 스모그 챔버는 선행연구에서 주로 수행한 초미세먼지의 생성 및 변환 뿐만 아니라 대기오염물질의 저감시설에 대한 평가를 위한 목적 등이 추가되어 제작되었다. 향후 국내 스모그 챔버를 이용하여 대기오염물질을 저감할 수 있는 다양한 연구가 수행될 수 있기를 기대한다.


This study reviewed the current research trends using smog chambers based on a pilot experiment on the formation of fine particulate matter through photochemical reactions. Among the recent major related studies, major issues on (1) gas phase reactions, (2) secondary organic matter formation, and (3) liquid phase reactions have been discussed. At last, design of Large-Scale Smog Chamber was suggested for the domestic construction to perform the secondary formation and reduction of precursor gases such as NO by titanium dioxide (TiO2), which is a relatively inexpensive, nontoxic, and easy to handle material for the further study. This study has shown that large-scale environment chambers can simulate the atmospheric photochemical reaction like-real-world for the reduction of fine particulate matter and the formation of the aerosol pathway.

The purpose of this study is to investigate the growth of fancy carp and plants and variation of water quality using recirculating aquaculture system for application of aquaponic system. The concentrations of DIN and T-N at FCP(Fancy carp + Plant) condition were lower than that of FCO(Fancy carp only), because the nutrients was absorbed to the plants. However the other items of water quality were almost same regardless of plants because of water exchanging of 20 %. In this study we conclude that the exchanging of water is very important to maintain water quality for keeping ornamental fish. The length of fancy carp was grown to 7.9 % and 6.7 % at FCO and FCP condition and the weight was increased to 25.3 % and 21.7 % at each conditions. However there was not the significant differences between the existence and nonexistence the plants. The leaf height, root length, leaf number and weight of Scindapsus were grown to 3.3 cm, 11.9 cm, 2.2 pieces and 7.9 g. On the other hand, the lettuce was grown to two times as 13.7 cm, 16.1 cm, 10.2 pieces and 8.6 g Therefore, this study provide emotional stability by rearing fancy carp, breath clean air by keeping air purification plant such as Scindapsus and eat fresh vegetable such as lettuce by application of plants to recirculating aquaculture system.

In this study, the sensitivity of spatial and temporal resolutions in sunshine modeling was numerically analyzed for the blocking effects of buildings on sunshine duration. Three-dimensional topography and buildings in the target area were numerically constructed with the spatial resolutions of 10 m, 5 m, and 1 m, based on the geographic information system(GIS) data. The solar position(azimuth and altitude angles) for the target area was calculated with the temporal resolutions of 60 min, 30 min, and 10 min on the winter solstice in 2020. The solar azimuth and altitude angles were reasonably well calculated in this study, compared with the data provided by Korea Astronomy and Space Science Institute [RMSE = below 0.3° and R2 = 0.999 for the solar azimuth angles, RMSE = about 0.3° ~ 0.4° and R2 = 0.999 for the solar altitude angles]. The sensitivity of spatial and temporal resolutions in sunshine modeling was 3.28 % ~ 11.37 % and 2.07 % ~ 6.84 % for the gross shadow area in the study domain, respectively. It is also suggested that the surface boundary condition with high resolution should be necessary for sunshine modeling.

In Korea, half of the annual rainfall is concentrated in summer season and there is a limit to apply watershed management plan focused on point sources only. As for the land use characteristics, 70 % of the total area is forest area and 20 % is agricultural area. Due to land use properties, the main water quality problems of river and lakes comes from non-point sources which are tend to be annually increased. Most non-point pollutants enter river or lakes through rainfall runoff. These are affected by the characteristics of land use and the season, and it is difficult to quantify and predict. These non-point sources are not only affecting the water quality of river or lakes, but also the surrounding landscape and water body ecosystem. Therefore, management of non-point sources is becoming more important. Effective watershed management plan need to the control and countermeasures of non-point sources containing various pollutants. This study attempts to understand the runoff characteristics of non-point sources using BASINS/WinHSPF model in the upper Anseong stream basin. The control and management plan of non-point sources can be effectively set up from this study.

Despite the government's policies to reduce fine dust in the transportation sector, such as regulations on the operation of emission-grade 5 diesel vehicles, subsidies for scraping old diesel vehicles, and Diesel particulate filter(DPF) installation, it does not contribute much to the reduction of fine dust. This study aims to contribute to the government's policy to reduce fine dust in the transportation sector by identifying the efficiency of reducing exhaust gas and fine dust of diesel vehicles through DPF Cleaning and presenting economic effects through benefit cost analysis. Comparing before and after DPF Cleaning, the reduction rate of PM10 and PM2.5 after DPF Cleaning was high, and according to the economic analysis results of the DPF Cleaning project, the current value of the cost(NPV) was KRW 40,279.6 million, indicating that the B/C(Benefit/Cost) was 2.7, As it is analyzed that it is worth 70.152 billion won in net present value, it is considered that there is a need to legislate the government's subsidy support policy for Cleaning of DPF and periodic Cleaning.

In this study, the long-term variability of air quality in eastern Jeollanam-do was evaluated by using the observed data of air pollutants(CO, SO2, NO2, O3, PM10) and heavy metals(Pb, Cd, Cr, Cu, Mn, Fe, Ni) during the year of 2000 to 2019. The annual and seasonal variability was analyzed by anomaly analysis compared to the average concentrations(normal values). As a result, the anomaly variability tended to decrease for the most of air pollutants and heavy metals. The decreasing trends of the long-term variability might be affected by the environmental policies for emission controls and clean & low-sulfur fuel use. However, the increasing trend of anomaly variability was shown in the case of O3 concentrations. Also, the insignificant decreasing trends of anomaly variability were represented for the some of the atmospheric heavy metals. Therefore, it was indicated that the continuous efforts should be required to improve air quality in eastern Jeollanam-do. In addition, the spatially sufficient observations should be necessary for the management of regional air quality by the eastern/western/central regions in Jeollanam-do.

In this study, moisture condensation rate, organic matter treatment efficiency and operating characteristics were compared when food waste with high moisture content was treated using the bio-dying method and the wet air control system. In addition, it was attempted to obtain experimental data on a system that can contribute to microbial activity by using it as the inflow circulating air. As a result, it is judged that it rises up to about 20,000 ppm and the microbial activity increases. The maximum temperature is 39 ℃, and considering the temperature decrease due to external heat dissipation loss, it is judged to be higher in reality. Organic matter showed a value of about 45 %, indicating that the pH value was repeated periodically from 4.5 to 6. Before the application of the wet air control system, the moisture content of the fermented product was distributed at a minimum of 40 % or more and showed an increasing form, whereas after the application of the wet air control system, the moisture content of the fermentation product was distributed at a maximum of 30 % or less. Condensation efficiency was 47 % and 63%, respectively, before and after the application of the wet air control system, which improved by 15% compared to before the application of the wet air control system. Before the application of the wet air control system, food consumed 6 times more calories than the input, but after the application of the wet air control system, the same amount of heat was consumed as that of the raw material. The basic operation data of the wet air control system for reuse of fermentation heat was secured so that the energy released during the condensing of the circulating air is recovered and used as energy.

The purpose of this study is to understand the current status and cause of the distribution of odor substances in the Yeosu National Industrial Complex and its surrounding areas. Samples were analyzed by collecting 90 samples at dawn, daytime and night from a total of 15 points, 9 points in the management area, 2 points in the boundary area, and 4 points in the affected area. The analysis items include 5 meteorological factors, complex odor, 22 types of the designated odors and other Volatile Organic Compounds (VOCs). At the MA3 (Fig. 1) point in the management area, the strict emission allowance standard for complex odors was exceeded three times, Ammonia, two types of sulfur compounds, two types of aldehydes, and six types of VOCs were detected, but they were within the standard. As a result of by calculating the odor contribution, the contribution of 74.9 % or more was found at the point where butyraldehyde was detected. Therefore, in order to prevent odors at the Yeosu Industrial Complex, measures to reduce aldehydes with high odor contribution should be prioritized, and it is necessary to simultaneously investigate through real-time harmful atmospheric measurement vehicles. Based on the contents presented in this study, if the system and policies reflecting the results of the odor occurrence survey of Yeosu National Industrial Complex and surrounding areas are supplemented, the odor environment of Yeosu National Industrial Complex will be sufficiently improved.

This paper estimated the amount of new agricultural waste(the waste of Tyvex and Layer thermal screen) and studied the reality of disposing Bale silage films. To study the reality of the disposal, survey was performed against farmers. In addition, the amount of agricultural waste was estimated based on the interviews against farmers and local government officers. It was found that the waste of Tyvex and Layer thermal screen were collected through a public collection site during late fall and early winter season. However, the public collection site is designated as a temporary place where only the legally-defined agricultural wastes can be collected and recycled. The waste of Tyvex and Layer thermal screen might be remained in the public collection site without being picked up. Bale silage films are also abandoned throughout a year into a public collection site. Bale silage film should be recycled from the public collection site because it is designated as EPR recycle-mandatory item. But waste haulers barely pick up the Bale silage film waste from the public collection site due to low profitability. It was analyzed the estimated amount of agricultural waste, 56.6 ton of the Tyvex waste, 283.6 ton of the Layer thermal screen waste and 175.5 ton of the Bale silage film waste per annum.
