초록

The purpose of this study is to evaluate quality of water on rivers in the Yeosu National Industrial Complex and to analyze the water quality factors that cause ecotoxicity. The subjects of the research were Namsucheon 4 stations, Jungheungcheon 2 stations and Sangamcheon 2 stations of Yeosu National Industrial Complex in Jeollanam-do. In addition, as a control group, water environment monitoring 8 stations in Jeollanam-do were selected for analysis. Physicochemical items and ecotoxicity were analyzed according to the Water Pollution Process Test Standards. Analysis results of water pollution items, BOD was 0.1 mg/L ~ 3.0 mg/L, TOC was 0.2 mg/L ~ 12.4 mg/L, SS was 0.4 mg/L ~ 72.0 mg/L, and T-N was 0.28 mg/L ~ 3.70 mg/L, T-P was 0.005 mg/L ~ 1.526 mg/L, total coliform was 0 ~ 1,200,000 total coliforms/100 mL, ABS was not detected ~ 0.15 mg/L, cyan was not detected ~ 0.07 mg/L, and organic phosphorus and phenols were not detected at all points. In terms of heavy metal analysis results, Mn was not detected ~ 0.505 mg/L, Fe was not detected ~ 1.633 mg/L, Zn was not detected ~ 0.733 mg/L, Cu was not detected ~ 0.014 mg/L, Ba was not detected ~ 0.052 mg/L, and seven items including Hg were not detected. Cyan was detected seven consecutive times in range of 0.01 mg/L ~ 0.07 mg/L at the H point. Compared with the 8 points of the water environment monitoring stations selected as the control group, the 8 points of the rivers around the Yeosu National Industrial Complex stations were managed relatively well, as there are no peculiarities. We calculated the toxicity value and evaluated the toxicity level of the river around the Yeosu National Industrial Complex using Daphnia magna. We expect that the result of this study will be used as basic data when government establish the policies of comprehensive management for rivers in the future.
