| Abstract | Indigo dye is an organic compound derived from a fermentation process. The rinsing water of the indigo dye is contaminated by the acid and alkaline agents needed for precipitation. It would affect fish or other aquatic animals if the indigo dye-contaminated water is released into a public water body the environment will be impacted. The objective of this study is to investigate the toxicity of indigo dye on silver barb (Barbonymus gonionotus) mortality at the concentration that kills 50% of the fish (LC50) and pathology in the gills. The exposure period was 96 hours. The fish were divided into 6 groups of 30 fries (weight 0.4 - 0.5 grams) and each was exposed to indigo dye-contaminated water (except the control group) with the concentration of indigo dye-contaminated water at 0.133, 0.150, 0.160, 0.167 and 0.171 ?g/mL respectively. After 96 hours of exposure, the survival rates were lowest for the concentration of indigo dye-contaminated water at 0.160 ?g/mL, 0.167 ?g/mL and 0.171 ?g/mL. The lethal concentration that kills 50% of the fish was 0.137 ?g/mL. The pathology in the gills in all groups exposed to the indigo dye-contaminated water had altered. Conclusion, wastewater should be treated before releasing it into water bodies. |
