A battery of four different toxicity tests were carried out including acute and chronic toxicity tests, such as the 96hr LC50 test using rainbow trout, and the seven day Ceriodaphnia dubia. A summary of the test results is shown in Table 3.9. Several effluent samples failed some or all of the toxicity tests, which was attributed to high effluent ammonia concentrations and/or BOD. Unlike persistent toxins, which present the 24 .
