The main purpose of this study is to search the water factor which influences to occurrence of the total coliforms. Occurrences rate of the total coliforms and the E. coli were 57.9%, 10.5% in 2007 and 47.4%, 23.7% in 2008 respectively. According to the result which examines the correlation analysis and a regression analysis, most the water factor which is effect was Na+(0.497, p<0.05) in appearance of the total coliforms and was Cl-(0.622, p<0.01) in appearance of the E. coli. The water factor that simultaneously influences to the total coliforms and the E. coli appearances was the Cl-. The predictable regression formula for appearance rate of the total coliforms was expressed as 0.462+0.028 [Na+]-0.644 [COD(Mn)]-8.889[PO4-P](R=0.930, R2=0.866, adjusted R2=0.839, p<0.05), and that of the E. coli was described as -0.012+0.004[Cl-](R=0.622, R2=0.387, adjusted R2=0.351, p<0.05).

This study was conducted to assess water quality of Dae stream in Busan using the periphyton. Species of the higher rank 10% in standing crops were Cymbella ventricosa, Aulacoseira granulata, Gomphonema olivaceum, Synedra ulna through the study. In addition, Fragilaria intermedia in the station 1 and 2, and Nitzschia palea in the station 3 and 4 dominated the periphyton community respectively. These species mainly appeared in the urban stream. Where input of pollutant is forecasted, standing crops of dominant species are investigated very highly. Also, standing crops of Nitzschia palea were higher in the pollution area such as polysaprobic than any other area. Water quality by the saprobic index were oligosaprobic in the station 1, β-mesosaprobic in the station 2 and 3, and α-mesosaprobic in the station 4. These results suggests that the pollution of Dae stream gradually increased with downstream due perhaps to the loading of sewage from the new residental complex.

본 연구는 낙동강 하류 20개 지점에 대하여 주위 환경 변화에 대응하기 위하여 식물플랑크톤상과 군집구조에 대한 조사를 실시하였다. 식물플랑크톤상과 군집은 2004년 1월부터 12월까지 매월 1회 조사하였다. 조사기간 동안 식물플랑크톤은 총 94속 196 분류군이 동정되었는데, 여름에 124분류군으로 가장 많은 종이 출현한 반면 겨울에 69분류군으로 가장적은 종이 출현하였다. 지점별 총 출현종수는 낙동강 하구인지점 20에서 92분류군으로 가장 많았고 지점 8에서 55분류 군으로 가장 적게 출현하였다. 분류군별 출현비율은 모든 계절에서 규조류(diatoms)가 40% 이상으로 가장 높았고 녹조류 (green algae)가 20%, 다음으로 남조류(blue-green algae)등의 순으로 조사되었다. 조사기간 동안 생태적 주요종은 60분류군이 조사되었는데, 그 중 광분포종은 46분류군, 오염지표종 25분류군, 적조원인종 21분류군, 우점종 8분류군, 출현빈번종 7분류군이었다. 지점간 유사도지수에 의한 군집분석의 결과, 20개 지점은 4개의 그룹으로 분류되어졌다. This study was focused on the investigation of the phytoplankton flora and community structure for changing of water environment at the rivers in the lower part of Nakdong river. The samples for this study were collected every month from Jan. 2004 To Dec. 2004. the 196 species belonged to 94 genera were identified during this study periods. The number of species was recorded the maximum 124 taxa in summer and the minimum 69 taxa in winter. We observed the maximum taxa (92 taxa) at the site No. 20 and the minimum taxa (55 taxa) at the site No. 8, respectively. Among the phytoplankton communities, diatoms were dominated over 40% of total phytoplankton groups. Subdominant groups were green algae (over 20% of total phytplankton groups). During this study periods, the 60 species were investigated ecologically significant species (46 cosmopolitic species, 25 pollution indicator, 21 redtide causative species, 8 dominant species, and 7 frequently occurred species). According to the cluster analysis by similarity index, the study sites could be divided into 4 groups.

식물 비생육지 토양의 깊이별 중금속 함량은 S1지점의 경우 1996년 오염토양 개선사업으로 S1지점 바로 위에다 남은 광미를 복토함으로써 광미 중금속이 강우에 의해 용탈되어 토양에 축적되기 때문에 오염되고 있는 것으로 판단되었고 S2지점은 오염토양 개선사업의 효과로서 표토에서 Zn과 Pb가 토양오염 우려기준을 초과하지 않았으며 Pb의 경우 $30\∼50cm$에서 토양오염 우려기준을 초과한 것은 광맥의 영향 때문이며 구리의 경우는 광산의 채광물로서 오염 정도가 심각하였다. 생육지 토양의 중금속 함량은 같은 표고상에 위치한 광산 위 지점(SP1, SP2, SP3)에서 볼 때 SP1지점에서는 Zn의 함량이 537.5 mg/kg로 가장 높았고, SP3지점에서는 Cu와 Pb의 함량이 가장 높았는데 이는 폐광산에 복토 사업을 했더라도 아직 토양 복원이 완전히 이루어지지 않아 강우와 풍화에 의한 광미의 영향 때문인 것으로 생각되며 SP2지점은 다른 지점보다 지대가 높아 광미의 영향을 적게 받는 것으로 생각된다. 식물체내의 중금속 함량은 차즈기>쑥>억새>살갈퀴 순으로 조사되었고 식물에 의한 연간 중금속 제거율 역시 차즈기가 가장 좋은 것으로 조사되었다. 특히 차즈기는 다량의 중금속이 축적되어 있고 중금속 오염 지역에 내성이 있는 지표종으로 생각될 수 있으며 본 식물의 중금속 축적 능력에 대한 더 많은 연구가 진행되어야 할 것으로 생각된다. This study was conducted to inform basic data for management of abandoned mine that was based on soil heavy metal concentration of the non-rearing and the rearing sites in Guundong Mine which had been completed of improve contamination soils, and examined into standard plant which had tolerances about pollution that analyzed into its accumulated heavy metals contents in the wild plant of naked soil. Consider form the result of contents by depth of soils heavy metals in the non-rearing sites, S1 point judged by contaminated to heavy metals of tailing leach after weathering caused by rainfall and permeate in S1 point soils when restored rest of tailing in 1996 restoration project. Lead of S2 point was not contaminated seriously by restoration and S3 point considered that heavy metals which leach by rainfall in the contaminated soils in mine vicinity accumulated in the abandoned paddy through river When heavy metals of rearing sites soils were examined from the view point of upside of mine point (SP1, SP2, and SP3) of same above the sea level, zinc (537.5 mg/kg) content of SP1 point was highest, and copper (535 mg/kg) and lead (141.5 mg/kg) in the SP3 point were high. To considered as orderly plenty of heavy metals in the plant were respectively in order, Perilla frutescens var. cauta KUDO (SP1 and SP4) >Artemisia princeps PAMPAN (SP2) > Miscanthus sinensis ANDERSSON(SP5) > Vicia angustifolia var. segetilis (THUILL.) K. KOCH. (SP2). Especially, there were plenty of heavy metals in P. frutescens var. acuta, so it judged as a standard plant which have tolerances about heavy metals pollution sites. Therefore, we need more study about the heavy metals accumulate ability of P frutescens var. acuta in future.
