LPG를 저장하는 지하공동의 수장막 시스템은 고압의 가스가 공동 밖으로 새어나가지 못하도록 원활한 지하수의 흐름과 안정적인 지하수두 유지가 필수적이다. 본 연구에서는 전남 여수 LPG공동의 유출수 및 주변 지하수의 수질특성을 파악하기 위하여 2007년 2월, 5월, 8월, 10월에 걸쳐 시료채취, 현장측정 및 실내 수질분석을 실시하였다. 현장 측정 결과 pH는 약산성에서 중성으로 나타났고 10월로 갈수록 증가하는 경향을 나타내었다. 전기전도도는 소금적치장과 인접한 관정의 경우 $10.47{\sim}38.50\;mS/cm$로 매우 높게 나타났다. 용존산소는 $0.20{\sim}8.74\;mg/L$로 매우 넓은 범위를 보였고, 산화환원전위는 평균 159 mV로 비교적 산화환경임을 나타냈다. 또 $Fe^{2+}$, $Mn^{2+}$의 농도는 대부분 3 mg/L 미만으로 나타났다. 수질유형은 유출수의 경우 4차례 모두 Na-Cl type로 나타났으나 지하수의 경우 소금적치장 인접 관측정은 Na-Cl type으로 높은 TDS를 보였다. 다른 지하수 관측정은 전형적인 $Ca-HCO_3$ type으로 나타났다. 미생물 분석결과 호기성세균의 수가 $573{\sim}39,520\;CFU/mL$로 비교적 높게 검출되었다. 본 연구에서 수리화학 및 미생물학적 특성을 분석한 결과 지하수와 유출수는 여수 저장공동의 운영에 있어서 큰 문제를 일으키지 않을 것으로 사료된다. 그러나 미생물 증식의 제어와 수리적 안정성을 유지하기 위해서는 지속적인 모니터링이 요구된다. Water curtain of an underground LPG storage cavern is a facility to prevent leakage of high pressure gases, for which groundwater should flow freely towards the cavern and groundwater level also must be stably maintained. In this study, in order to evaluate qualities of seepage water and surrounding groundwater of an underground LPG storage cavern in Yeosu, 4 rounds of samplings, field measurements and laboratory analyses (February, May, August, October of 2007) were conducted. According to field measurements, pH was weak acidic to neutral but it gradually increased with time. Electrical conductivity (EC) of groundwater near a salt stack showed very high values between 10.47 and 38.50 mS/cm. Dissolved oxygen (DO) showed a very wide range of 0.20~8.74 mg/L and a mean of oxidation-reduction potential (ORP) was 159 mV, which indicated an oxidized condition. Levels of $Fe^{2+}$ and $Mn^{2+}$ were mostly less than 3 mg/L. All of seepage waters showed a Na-Cl type while only groundwater near the salt stack showed a Na-Cl type with a high total dissolved solid. The other groundwaters exhibited typical $Ca-HCO_3$ types. Levels of aerobic bacteria were mostly very high (573-39,520 CFU/mL). Based on the analyses of these hydrochemistry and biological characteristics, it is concluded that there are no particular problems in groundwater and seepage water, which not causing a trouble in the cavern operation. However, both for control of bio-clogging and for sustainable operation of the water curtain system, a regular hydrochemical and microbiological monitoring is required for the seepage water and surrounding groundwater.

경주 국가지하수관측소 일자료로 본 경주지진 영향

Earthquakes of M5.1, M5.8 and M4.5 occurred in September 12 and 19 respectively in Gyeongju, Gyeongbuk Province. Theses earthquakes inflated fears of people and highlighted necessity of detailed countermeasures because we have considered our country is safe to earthquakes. In the meanwhile, earthquake also impacts groundwater and thus it was recently reported that the Gyeongju Earthquakes affected groundwater there. This study evaluates daily groundwater data collected from five national groundwater monitoring stations (Geoncheon, Sannae, Oedong, Yangbuksin, Cheonbuk) in Gyeongju. The analysis revealed that only groundwater level of bedrock monitoring well hosted in andesite exhibited earthquake impact while no wells in the other four stations hosted in sedimentary rocks showed substantial responses to the earthquakes. This may be derived from the difference of seismic velocity of hosting rocks as well as epicenter distance. Special interest on groundwater monitoring is required to predict earthquakes as precursory phenomena.

입상 활성탄을 이용한 형광물질 추적자시험 적용성 연구

이진용,황현태,이명재,김용철,염병우,Lee, Jin-Yong,Hwang, Hyoun-Tae,Yi, Myeong-Jae,Kim, Yong-Cheol,Yum, Byoung-Woo 한국지하수토양환경학회 2007 지하수토양환경 Vol.12 No.4

최근에 형광물질을 이용한 추적자 시험이 빈번해지고 있다. 본 연구에서는 형광물질 추적자 시험시 농도측정 방법으로서 입상 활성탄을 이용하는 방법의 적용가능성을 실내 및 현장실험을 통해 평가하였다. 실내실험 결과 로다민 WT 및 우라닌 개별용액의 경우 활성탄 흡착 농도는 실제 표준농도와는 일부 차이가 있지만 각 표준농도와 선형성은 매우 뛰어난 것으로 나타났다. 또한 $10{\mu}g/L$ 이상의 형광물질 농도에서는 활성탄의 적용성이 뛰어났다. 한편 두 형광물질을 혼합한 경우에는 간섭의 영향으로 활성탄 적용성이 떨어졌다. 실제 현장에서 활성탄을 이용하여 추적자 시험을 한 결과, 통상적으로 수행하는 직접적인 물시료 채취분석법과 비교하였을 때 활성탄을 이용한 흡착방법도 충분히 현장 적용성이 있으며 저농도에서는 습식 그리고 고농도에서는 건식으로 분석한다면 보다 정확한 형광물질 농도측정이 되는 것으로 나타났다. 특히 오염물질 확산 평가 등이 목적이 아니라 추적자 물질의 도달확인(즉 수리적 연결성 진단)이 주요 목적이고 추적자시험의 예상 소요기간이 길다면 활성탄을 활용한 방법은 매우 비용경제적일 것으로 사료된다. In recent tests using tracer have been frequently conducted by fluorescent tracers. In this study, granular activated charcoal (GAC) as a detector for the fluorescent tracers (rhodamine WT and uranine) was investigated through laboratory and field tests. In the laboratory tests, tracer concentrations of rhodamine WT and uranine determined by the GAC were slightly different from those of standard solutions but they were excellent in linearity. Results show that GAC is excellent as tracer detector when concentration of the fluorescent tracers is greater than 10 & micro; g/L whileas no obvious differences in mixed solutions of the two tracers due to interferences. Compared to conventional methods of water sampling, field results shows a high potential of GAC as a tracer in the field. Our results also show that wet analysis is better for the lower concentrations of tracers whileas dry analysis is good for high concentrations of tracers. This study demonstrates that fluorescent tracer detection using the GAC is very useful and economical for a hydraulic connection between target areas and very longer period of the tracer test.

Objective : This experimental study was designed to determine the effects of BPT on obesity in vivo and in vitro. Methods : in vitro, BPTn extracts of various concentration(50, 100, 200 ${\mu}g/m{\ell}$) were added in 3T3-L1 cell. Adipocyte differentiation was measured by Oil Red O staining and Morphological examination. The expression of $C/EBP{\alpha}$ and $PPAR{\gamma}$ receptor was measured by western blot assay and RT-PCR in vivo, Rats were orally administered BPT daily for consecutive four weeks before poloxamer-407 induced hyperlipidemic state. The rats were sacrificed 24 hrs later for poloxamer-407 treated and then serum triglyceride, total cholesterol were measured ; Rats were orally administered BPT daily for consecutive four weeks before triton WR-1339 induced hyperlipidemic state. The rats were sacrificed 40 hrs later for triton WR-1339 treated and then serum triglyceride, total cholesterol were measured ; Rats with obesity were induced by the high fat-diet for six weeks and then serum triglyceride, total cholesterol, LDL-cholesterol, triglyceride, HDL-cholesterol, hydroxy radical, superoxide dismuatse activity were measured. Results : In vitro, The 3T3-L1 cells' differentiation was significantly decreased by BPT. The expression of $C/EBP{\alpha}$ and $C/EBP{\beta}$ was decreased by BPT. In vivo, BPT significantly reduced serum triglyceride, total cholesterol contents in poloxamer-407 treated rat. BPT significantly reduced serum triglyceride contents in Triton WR-1339 treated rat. Total cholesterol also reduced but did not show a significant change. BPT significantly reduced body weight gain of rat and adipose tissue mass of rats and serum triglyceride, LDL-cholesterol contents and significantly increased HDL-cholesterol, HTR(HDL-cholesterol/Total-cholesterol) in rats with obesity induced by the high fat-diet. BPT reduced blood lipid peroxide, hydroxy radical and increased superoxide dismuatse(SOD) activity.
