| Abstract: | The effect of toxicity of dye effluent was evaluated by Japanese medaka (Oryzias latipes) from embryo to fry. 4 samples were obtained from the discharge of dye factories. The results of 96 h acute toxicity test showed that sample 3 and 4 had acute toxicity to juvenile fish whereas acute toxicity of sample 1 and 2 was not significant. The acute toxicity units of 4 samples were 0.47, 0.53, 9.93 and 1.68 TUa, respectively. Sample 1 and 2 are mildly toxic, sample 3 was medium toxic and sample 4 was low toxic. For 14 d chronic toxicity, the results showed that the lethal of embryos in sample 1, 3 and 4 were observed, the no observed effect concentrations (NOEC) for hatching rate were 90%, 20% and 33%, respectively. The hatching time are delayed in group of 52% and 64% of sample 4 and significantly different with the control (p>0.05). The inhibition of hatching of embryo were significant, NOEC for hatching rate was 2.5%, and EC25 was 39.2%. The chronic toxicity units of the four samples were 1.11, 40, 5 and 3.03 TUc, respectively. The fish fry were resulted in death by the treatment groups of sample 1 and 3 after 3 d exposure. NOEC for survival rate of fish fry are 90%, 20%, 10% and 64%, respectively. |
