Summary, Etc. Note: |
Abstract: The 96-hour LC50's for chlorine ranged from 0.156 mg/liter for channel catfish to 1.41 mg/liter for black bullheads in standardized laboratory tests. The toxicity of chlorine was influenced little by pH, temperature or water hardness. Chlorine at 0.25 and 0.05 mg/liter effectively detoxified antimycin. The half-life of biological activity for antimycin and chlorine ranged from 1.1 hour at pH 6.5 to 1.5 hours at pH 9.5. Chlorine readily detoxified antimycin at pH 6.5, 7.5 and 8.5, but not at pH 9.5. |
