  • Abstract The purpose of study is to identify the relationship between stable isotope composition of reed stems in coastal and understand the structure of the fish community in 10 lagoons along the East Sea. The fish species composition (particularly, anadromous fish species) and relative abundance of trophic guilds was influenced by difference of geomorphic characteristics among lagoons. Reed stems ${\delta}^{13}C$ and ${\delta}^{15}N$ values ranged from $-28.40{\pm}0.11$‰ to $-26.87{\pm}0.25$‰ and $-1.09{\pm}1.45$‰ to $12.08{\pm}0.53$‰, respectively. The differences in reed stem ${\delta}^{15}N$ values might be associated with anthropogenic landuse and the geomorphic characteristics among lagoons. These results provide useful information to improve the conservation of fish habitats (biodiversity), preserve lagoon habitats and contribute to watershed management effect against anthropogenic pollution from watershed in these lagoon ecosystems.

  • This study examined the halophyte community and soil analysis according to habitat in representative 18 salt marshes of southern and western coasts of Korea from July 2006 to April 2008 and suggested basic materials for vegetational restoration of these aras. First, the survey area was classified into coastal and estuarine marshes. Then, the coastal marshes were classified into clay marsh, sand gravel marsh, and sand marsh, and the esturarine marshes, into salt swamp and estuary marsh. Major plant communities according to habitat pattern were Phragmites communis, Carex scabrifolia, and Suaeda japonica community in the clay marsh; Phragmites communis, Zoysia sinica, Carex scabrifolia, Salicornia herbacea, Artemisia fukudo, Suaeda martima community in the sand gravel marsh; Elymus mollis, Carex kobomugi, and Vitex rotundifolia community in the sand mars; Phragmites communis, Zoysia sinica, Suaeda martima, and Carex scabrifolia community in the salt swamp, and Suaeda japonica, Phragmites communis, Carex scabrifolia, and Suaeda asparagoides community in the estuary marsh. The soil environment of halophyte community area showed a difference to soil and halophyte community according to habitat characteristics of halophyte. Thus, to restore salt mashes in the coast area, it is advantageous for the stable settlement, germination, and growth of halophyte to grasp physical and physicochemical characteristics of habitat soil in the salt marshes, to select halophyte suitable to these habitat conditions, and to expand gradually in the natural vegetation area after transplantation.

  • A sewage was treated using serially combined vertical and horizontal flow zeolite-filled reed bed. The sewage from the student dormitory of Changwon National University was fed into the reed bed for 10 minutes every 6 hours at the hydraulic load of 314 $L/m^2{\cdot}day$. The reed bed depth was 100cm and the zeolite mixture was filled in the reed bed. The mixture consisted of the same volume of two types of zeolite ; 0.5~1mm and 1~3mm in diameter. pH value decreased in vertical bed, while it increased in horizontal bed. But DO concentration in the effluent of both beds was higher than that in the influent. Average removal efficiencies of the entire treatment system were 99.22% SS, 95.56% BOD, 91.02% $COD_{Cr}$, 87.78% $COD_{Mn}$, 45.87% T-N, 99.88% $NH{_4}^+-N$ and 71.17% T-P. Most of T-N in the effluent was $NO{_3}^--N$. However, the concentration of $NO{_2}^--N$ in the effluent was lower than 0.04 mg/L. All removal efficiencies did not show a remarkable seasonal change.

  • Leaf litter breakdown rates of the Phragmites australis, Zizania latifolia and Typha angustifolia were determined at the lower Nakdong River from Nov. 1998 to Sept. 1999. The relationship between leaf litter breakdown of three and abundance of aquatic invertebrates was investigated. Aquatic invertebrates collected in the litterbags were 11 family, 11 species (mean density: $222\;ind./m^2$ , n = 792), and Chironomidae was dominant. Mean density of Chironomidae in the litterbags were different according to the aquatic plant species: Z. latifolia ($180\;ind./m^2$, n = 264) T. angustifolia ($187\;ind./m^2$, n = 264) P. australis ($95\;ind./m^2$, n = 264). The breakdown of Z. latifolia was the shortest, and that of T. angustifolia was shorter than P. australis. Overall, the breakdown rate at floating layer was faster than that of submerged layer in all of three species and differences of the breakdown rate between open bags and closed three species and differences of the breakdown rate between open bags and closed bags were not found.

  • This study evaluated the ecotoxicological properties of livestock waste water treated by a LID (Low Impact Development) system, using a mixture of bio-reeds and bio-ceramics as suitable bed media for a subsequent treatment process of a livestock wastewater treatment plant. The relationship between the pollutant reduction rate and the ecotoxicity was analyzed with the effluents from the inlet pilot plant, with vegetated swale and wetlands and the batch type of an infiltration trench. Each pilot plant consisted of a bio process using bio-reeds and bio-ceramics as bed media, as well as a general process using general reeds and a bed as a control group. The results indicated that, after applying the HRT 24 hour LID method, the ecotoxicity was considerably lowered and the batch type pilot plant was shown to be effective for toxicity reduction. The LID method is expected to be effective for water quality management, considering ecotoxicity by not only as a nonpoint source pollution abatement facility but also, as a subsequent treatment process linked with a livestock manure purification facility. It is necessary to take the LID technic optimization study further to apply it as a subsequent process for livestock wastewater treatment.

  • This survey was conducted from May 2017 to August 2018 as part of the National Marine Ecosystem Surveys sponsored by MOF (Ministry of Oceans and Fisheries) and KOEM (Korea Marine Environment Management Corporation). The survey was conducted at 157 stations including intertidal zones, coastal sand dunes and beaches. A total of 72 species of halophytes were identified and the total vegetated area was $1,813,546m^2$ in coastal waters of Korea. In the west coast region, Suaeda japonica was the dominant species, Phragmites communis in the southern coast, and Carex kobomugi in the east coast. Phragmites communis was the most dominant with $1,136,643m^2$ (62.7%) in the whole surveyed area. The top 11 dominant plants are Phragmites communis, Suaeda japonica, Suaeda maritima, Zoysia sinica, Carex kobomugi, Elymus mollis, Suaeda malacosperma, Phacelurus latifolius, Triglochin maritimum, Carex pumila and Carex scabrifolia, and Phragmites communis and Suaeda japonica accounted for 75.9% of the total vegetated area. The distribution of halophyte on the coast of Korea was determined by the habitat types rather than the climate ranges, and there was a difference in the species diversity and habitat range of the halophyte depending on the habitat diversities within the same area.

  • 홍조류의 일종인 우뭇가사리에서 채쥐한 섬유소로 제작된 종이(펄프)가 최근 서영범 충남대학교 임산공학과 교수에 의해 공개됐다. 지금까지 목재 펄프가 아닌 비목재 펄프에 대한 도전은 많았다. 볏짚, 사탕수수, 갈대, 대나무 등 주로 지상에서 채취되는 원료를 사용했는데, 해조류를 활용한 것은 지극히 예외적인 경우로 더욱 큰 관심을 불러일으키고 있다.
