Carotenoid Pigments from Suspended and Sinking Particulate Matter in Prydz Bay, Antarctica
Noh, Il ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1357~1371
DOI : 10.5322/JES.2011.20.11.1357
Suspended and sinking particles were collected during ODP Leg 119 to the Indian Ocean sector of the Antarctic Ocean. Field work was carried out at four sampling sites in Prydz Bay. Two of these sites were located in the Outer Bay, and two in the Inner Bay. At the four locations, a total of ten deployments of a sediment trap array were made. The concentrations of carotenoids both in suspended and sinking particulate matter in Prydz Bay were analyzed using HPLC. Fucoxanthin was the dominant carotenoid pigments both in suspended and sinking particles. The present study also indicates that 19'-hexanoyoxyfucoxanthin-containing prymesiophytes (Phaeocystis spp.) was abundant in the study area. The flux rates of carotenoids were generally highest at 50 m, and approximately double the flux rates at deeper horizons, however, at Inner Bay sites, the mean flux rates of carotenoids were greatest at 200 m, and 3 times greater than that of 50 m. Such anomalous high fluxes at 200 m imply that grazers were locally abundant between 100 m and 200 m at these sites close to land, and this hypothesis is supported by visual evidence of lots of fecal pellets in the 200 m trap. Integrates standing stocks versus sinking pigments data support that particulate material in Prydz Bay was not recycled rapidly.

This research had been conducted from May to October 2007, studying 110 residents of G, Y, H industrial area in Jun-nam province. It is designed to understand the difference in levels of indoor, outdoor and personal exposure to VOCs(benzene, toluene, Ethylbenzene) and a health risk assessment was conducted to see if there was any fatal cause from carcinogenic or non - carcinogenic elements from a case group and a control group in all areas as well as each different area. In the case of benzene in the air, the geometric levels for the case group are indoor, outdoor and personal exposure; a higher than for the control group. As a results of the Monte - Carlo study about benzene, it shows that the case group's carcinogenicity is higher than that of the control group and it also shows that, on the CTE, RME condition and Monte - Carlo analysis, all subjects are seen to exceed the carcinogenicity tolerance
of US EPA. In the case of toluene, ethylbenzene on the CTE, RME condition and Monte - Carlo analysis, these do not exceed the non - carcinogenic standard of 1, but toluene in RME condition for both groups' personal exposure and the indoor and personal exposure of ethylbenzene in Monte - Carlo show that these seem to exceed the standard.

Yoon, Sung-Jin ; Park, Gyung-Soo ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1383~1394
DOI : 10.5322/JES.2011.20.11.1383
Environmental impacts of suspended solids (SS) released in coastal area by dredging, reclamation and construction can cause serious damages to coastal habitats and benthic organisms. Acute toxicity tests (4-7 days) were conducted to identify the relationship between SS concentration and mortality of three marine benthic species; benthic copepod (Tigriopus japonicus) adult, Pacific abalone (Haliotis discus hannai) spat, and olive flounder (Paralichthys olivaceus) fry. Benthic copepod was the most sensitive to SS followed by olive flounder fry and Pacific abalone spat, with an
(lethal concentration of 50% mortality) value of 61.0 mg/L and LOEC (lowest observed effective concentration) value of 31.3 mg/L for benthic copepod. LOEC and 7 day-
for Pacific abalone spat were 500.0 mg/L and 1887.7 mg/L, and those for olive flounder fry were 125.0 mg/L and 156.9 mg/L, respectively. The tolerance limits of the test species to SS revealed the various concentration ranges of SS, which reflects the physiology and ecology of the test species. These results are very valuable for the determination of SS concentration of effluents released into the coastal area by dredging, reclamation and construction etc. Also, sharp increase of SS can cause long-term damages to the benthic and sessile fauna by blanketing of benthic substratum. These experimental procedures for marine bioassay and acute toxicity results can be a useful guideline for practical management planning of SS discharge into coastal area.

Baek, Seung-Hyuk ; Kim, Hyung-Jin ; Kwon, Young-Shik ; Kim, Seung-Sup ; Choi, Yoon-Geun ; Chung, Chan-Kyo ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1395~1401
DOI : 10.5322/JES.2011.20.11.1395
In this study, Life Cycle Assessment(LCA) has been carried out to evaluate the environmental impacts of a metallic can. A 360 mL volume of an aluminum can bottle was used as the functional unit. The results of Life Cycle Inventory(LCI) showed that iron ore and coal were the major parts of the input materials, whereas aluminum can products, carbon dioxide, wastewater, and hazardous wastes were those of the output ones. According to LCA weighting, it was observed that the most significant impact potential was found to be global warming(49.11%) followed by abiotic resource depletion(47.72%). In the whole system, cold rolled steel coil showed the largest environmental impact potential(86%), followed by electricity(14%). Meanwhile, lubricating oil and industrial water had the minor portion of the total environmental impact potentials. It was suggested that the use of cold rolled steel and electricity should be the main source for
, resulting in the big impact on global warming.
A Study on the Transport of Anchovy Engraulis japornicus Egg-larvae in the South Sea of Korea
Kim, Dong-Sun ; Bae, Sang-Wan ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1403~1415
DOI : 10.5322/JES.2011.20.11.1403
To understand the transport of anchovy egg-larvae, an integrated model consisting of a hydrodynamic model and a three-dimensional Lagrangian diffusion model was used for the anchovy Engraulis japornicus egg-larvae trace. Fist, in order to determine the circulation characteristics of the South Sea of Korea, residual flow according to tide, density and wind effect was investigated. In offshore regions, tide-induced residual current tends to flow eastward during the spring tide and westward during the neap tide. Residual flow is irregular due to the bottom topography in the coastal area. No special tendency was apparent in the open sea. Especially, the flow in the offshore regions showed results similar to that of the Tsushima Warm Current. The transport of anchovy egg-larvae is decided the physical properties of sea water. It is estimated that anchovy eggs spawned near the Jeju Island travels offshore, rather than to coastal areas, and grow in the front area between the coastal sea and offshore regions.

Ju, Jin-Hee ; Kim, Hya-Ran ; Yoon, Yong-Han ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1417~1423
DOI : 10.5322/JES.2011.20.11.1417
For evaluating the effect of various organic fertilizer ratios on the Spiraea
bumalda 'Gold Mound' growth, a container green wall system experiment was conducted in a greenhouse at Konkuk university. The experimental planting grounds were prepared with different organic fertilizer ratios (
) and with drought tolerance and an ornamental value Spiraea
bumalda 'Gold Mound' was planted. The change in soil moisture contents, plant height, number of branches, number of dead leafs, number of leaf, number of shoots, length of node, length of leaf, width of leaf, root-collar caliper, chlorophyll contents and survival rate were investigated from April to Jun 2010. 1. The result of soil moisture contents was analyzed with weight unit in the container green wall system during the dry summer season. The soil moisture contents were significantly enhanced in the container green wall system in increasing order as the amount of fertilizer level increased
. 2. Compared to the control treatment (amended soil with 100% + organic fertilizer 0%) application, the highest plant growth was observed in the treatment of
(amended soil with 67% + organic fertilizer 13%) application. However, the differences between the organic fertilizer ratio treatments of
, and the
organic fertilizer application were mostly not significant. 3. The survival rate increased with the increasing application of organic fertilizer, but in the control treatment (amended soil with 100% + organic fertilizer 0%) application all the plants died. Experimental results from the presented study clearly demonstrated that the organic fertilizer improved the survival rate more than the Spiraea
bumalda 'Gold Mound' growth at different levels of organic fertilizers. This strain can be utilized as a plant growth application in living wall systems during the dry summer season. Therefore, Spiraea
bumalda 'Gold Mound' is expected to be a highly valuable shrub for the green wall system if it should be considered in integration with stormwater retention or as a soil conditioner for increasing soil water contents in planting ground.

Lee, Chung-Il ; Han, Moon-Hee ; Jung, Hae-Kun ; Kim, Sang-Woo ; Kwon, Ki-Young ; Jeong, Hee-Dong ; Kim, Dong-Sun ; Park, Sung-Eun ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1425~1435
DOI : 10.5322/JES.2011.20.11.1425
Time-series change in Gyeongpo beach shoreline was illustrated using DGPS(Differential Global Positioning System, resolution < 0.6m) observation from April, 2009 to April, 2010. The shoreline was subdivided into 12 areas, and westward and eastward movement of shoreline position at each area was calculated. In general, the shoreline moved toward sea during summer, and it moved toward land during winter. The southern and northern part of the shoreline had different pattern in time-series. The shoreline in the southern part moved toward sea during summer and moved toward land during winter, but time-series pattern of the shoreline in the northern part was more complicated than that in the southern part. Pattern of time-series change in the northern part was made up of three different types; the first is that the shoreline moves continuously toward land, and the second thing is that the shoreline's movement is the opposite to the southern part, and the third thing is that the shoreline maintains a state of equilibrium without any great fluctuation. The total length of the shoreline was the largest during winter and the smallest during summer. In general, time-series change in the shoreline had positive(+) relationship with sea surface pressure and wind speed.

Kam, Sang-Kyu ; Hyun, Sung-Su ; Lee, Min-Gyu ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1437~1445
DOI : 10.5322/JES.2011.20.11.1437
The adsorption performance of lead ion was studied using five zeolites (Na-P1, sodalite (SOD), analcime (ANA), nepheline hydrate (JBW), cancrinite (CAN)) synthesized from Jeju scoria. The adsorption performances of lead ion decreased in the order of Na-P1 > SOD > ANA > JBW > CAN. These results showed that the synthetic zeolite with a higher cationic exchange capacity showed a higher adsorption performance. The uptake of lead ion by synthetic zeolites were described by Freundlich model better than Langmuir model. The adsorption kinetics of lead ion by synthetic zeolites fitted the pseudo 2nd order kinetics better than pseudo 1st order kinetics. The effective diffusion coefficients of lead ion by synthetic zeolites were ten times higher than the zeolite A synthesized from coal fly ash.

In this study, the method of estimating hydrologic information (water depth, submerged period etc.) on the proper selection of construction point and scale as well as vegetation type suggested for the design of natural riparian rehabilitation structure. Long-term comprehensive watershed model SWAT-K(Korea) was applied to this purpose. Flow duration analysis was conducted to analyze the hydrologic characteristics of Pyungchang watershed at which the 'bangtul' construction method was tested. For this purpose 20 years (1989-2008) rainfall runoff analysis was carried out. Based on the simulated daily streamflow data, flow duration curve was made to analyze the flow characteristics, and the water depth hydrograph was made to analyze the water depth distribution at the cross section. Finally, the information for the selection of proper vegetation according to the submerged period is suggested.
Estimating Ozone Sensitivity Coefficients to NOx and VOC Emissions Using BFM and HDDM for A 2007 June Episode
Kim, Soon-Tae ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1465~1481
DOI : 10.5322/JES.2011.20.11.1465
The accuracy of ozone sensitivity coefficients estimated with HDDM (High-order Decoupled Direct Method) can vary depending on the
(Nitrogen Oxides) and VOC (Volatile Organic Compound) conditions. In order to evaluate the applicability of HDDM over the Seoul Metropolitan Area (SMA) during a high ozone episode in 2007 June, we compare BFM (Brute Force Method) and HDDM in terms of the
-order ozone sensitivity coefficient to explain ozone change in response to changes in NOx and VOC emissions, and the
-order ozone sensitivity coefficient to represent nonlinear response of ozone to the emission changes. BFM and HDDM estimate comparable ozone sensitivity coefficients, exhibiting similar spatial and temporal variations over the SMAduring the episode. NME (Normalized Mean Error) between BFM and HDDM for the episode average
-order ozone sensitivity coefficients to NOx and VOC emissions are less than 3% and 9%, respectively. For the daily comparison, NME for the
-order ozone sensitivity coefficients are less than 4% (
> 0.96) and 15% (
> 0.90), respectively. Under the emission conditions used in this study, two methods show negative episode average
-order ozone sensitivity coefficient to
emissions over the core SMA. The
-order ozone sensitivity coefficient to
emissions leads ozone to respond muchnonlinear to the reduction in
emissions over Seoul. Nonlinear ozone response to reduction in VOC emissions is mitigated due to the
-order ozone sensitivity coefficient which is much smaller than the
-order ozone sensitivity coefficient to the emissions in the magnitude.

Yoo, Young-Eok ;
Journal of Environmental Science International, volume 20, issue 11, 2011, Pages 1483~1497
DOI : 10.5322/JES.2011.20.11.1483
The result of comparison and analysis study of institutionalization and exchange status of environmental education in South Korea, the People's Republic of China, and Japan, Northeast Asian countries that are closely related to Korea, is summarized as the following: First, this study shows that the process of environmental education institutionalization requires an instigation. For example, a specific environmental policy is established after raising awareness to modify environmental policies, as the result of aggravation of damage due to pollution. Therefor, it is the necessary process for the establishment of an environmental policy in order to proceed environmental education institutionalization. Second, even though institutionalization processes of environmental education for the three countries are considered to be very similar, differences are apparent if one carefully examines the content of environmental education for each country. In particular, South Korea, the People's Republic of China, and Japan all agree that environmental education is necessary, but differ in their ideas of main body for advocating institutionalization, as well as maintenance level of environmental education. Third, the order of establishment of environmental education institutionalization is Japan, South Korea and China and there exists about a 10 years time gap between each country. Fourth, the environmental education exchange was formed between South Korea and the People's Republic of China and between South Korea and Japan, first. Then it was enlarged to TEMM(Tripartite Environment Ministers Meeting) and TEEN(Tripartite Environmental Education Network) among three countries.

Practical disposal of transformer insulation oil laden with PCBs (polychlorinated biphenyls) by a chemical treatment has been studied in field work. The transformer insulation oil containing PCBs was treated by the required amounts of PEG (polyethylene glycol) and KOH, along with different reaction conditions such as temperatures and times. The reaction of PEG with PCBs under basic condition produces arylpolyglycols, the products of nucleophilic aromatic substitution. Removal efficiencies of PCBs in insulation oil before and after chemical treatment were examined. The removal efficiency of PCBs was very low at lower temperatures of 25 and
. Under the reaction condition of PEG 600/KOH/
/2hr, removal efficiency of PCBs was approximately 70%, showing completely removal of PCBs containing 7~9 chlorines on biphenyl frame which appear later than PCB IUPAC Number 183 (2,2',3,4,4',5',6-heptaCB) in retention time of GC/ECD. However, when increasing the reaction temperature and time to
and 4 hours, removal efficiency of PCBs reached 99.99% without any formation of PCDDS/PCDFs during the process. Such reaction conditions were verified by several official analytical institutions. In studying the reaction of PEG with PCBs, it confirmed that the process of chemical treatment led to less chlorinated PCBs through a stepwise process with the successive elimination of chlorines.
