| The effect of cement on survival, LC/sub 50/, safe concentration (SC) and application factors of pollutant (AF) for pond smelt, Hypomesus olidus were investigated for 96 hours. Mean body length of pond smelt used in this experiment was 8.6¡¾1.2 cm. Cement concentrations established in this experiment were 0 (control group), 10, 25, 50, 100, 250, 500, and 1,000 ppm, respectively. All fishes were dead in concentration more than 500 ppm cement within 4 hours. The LC/sub 50/ to cement toxicity was 123.03 ppm for 48h, 91.20 ppm for 72 h and 58.88 ppm for 96h. The value of SC and AF to cement toxicity for this species were 2.64¡9.14 ppm and 0.045¡0.155, respectively. |
