摘要：Acute and chronie toxicities of sediment elutriate and surface water samples ollected at Lake Shihwa were evaluated using standard toxicity testing organisms including Vibrio fischeri,Daphnia magna and Moina macrocopa. Acute exposure resulted in toxic ffects in all surface water or sediment elutriate samples,excepl for those cllected from the reed swamp and Okgu stream. The rainy season influenced the toxicity of the water samples. presumably either by dilution of point discharge or through introduction of non-point source contami- nants through runoff. In the sediment. elutriate and surface water samples. copper was detected above potential- ly lethal concentration,which may in purt explain the observed loxicity. Considering acute toxieities of the sur- face water streams that direet to the Lake Shihwa,efforts should be waranted to control and reduce discharge of point and non-point sources along Lake Shihwa.
