Abstract | Ninety-six hour acute toxicity bioassays were employed to determine the tolerance of juvenile coho salmon to chlorinated stabilized kraft mill effluent (SKME). In addition the effect of chlorinated SKME on the growth of juvenile coho salmon in six and ten day experiments was studied. Results of the acute toxicity tests indicated that the addition of as low as 1 mg/l of total residual chlorine to 100 percent SKME could cause acute toxicity in effluent concentrations as low as 18 percent. Since the non-chlorinated SKME used in these tests was not acutely toxic to the salmon, it appeared that chlorine or some chlorinated material formed in the chlorinated SKME was responsible or the cases of acute toxicity. Effects of chlorinated SKME on the growth of the coho salmon were not clearly defined at the ch1oriie and SKME concentrations tested. |
