ABSTRACT

This study was conducted to survey the effect of high-temperature thermal discharge into stream on macroinvertebrate. The survey was conducted from 2021 to 2022 in three rivers: Stream A, B located in Gyeonggi-do and Stream C located in Chungcheongbuk-do. The survey points were selected upper stream and lower stream, centering on the thermal effluent where the thermal discharge was discharged, and the species, Biological community analysis, feeding functional group, and EPT-Group ratio were analyzed. The average water temperature difference between upper stream and lower stream points is at least 5.1°C to a maximum of 11.6°C. As a result of biological community analysis, a stable community state with a relatively low dominance index in the upper stream and a high biodiversity index was shown. The EPT-Group ratio also showed a relatively high ratio upper stream. Overall, it showed better aquatic environment upper stream than lower stream affected by Thermal discharge. In the future, it is expected that more diverse ways to improve the aquatic environment will be able to be presented through continuous and complex research on the aquatic environment and aquatic ecosystem.
