| This study was investigated to the assessment of organic pollution using attached diatom assemblages in the Shinchon stream on April, June, September and December 1999. Diatoms were identified total 74 taxa which composed of 68 species, 4 varieties and 2 unidentified species. The Centrales were 5 taxa and Pennales were 69 taxa. Dominant species were Navicula subminuscula, Navicula saprophila and Nitzschia palea which were saprophilous taxa to organic pollution. N. palea was dominant species at st. $1{sim}3$ on April, June and September and N. subminuscula was recorded as dominant species at st. 4 on June, September and December. N. saprophila was dominated only at station 4 on April. DAIpo values were ranged $0.4{sim}15.3$ at all stations from April to December and the water qualities were polysaprobic states except to ${alpha}-mesosaprobic$ state at st. 1 on June. If Navicula sp. was identified as saprophilous taxa, DAIpo value of this station will be 3.5 and water quality of the station will be polysaprobic state. This stream was assessed the water qualities of polysaprobic states. |
