The use of short-term toxicity tests including subchronic and chronic tests in the NPDES Program is especially attractive because they provide a more direct estimate of the safe concentrations of effluents in receiving waters than was provided by acute toxicity tests, at an only slightly increased level of effort, compared to the fish full life-cycle chronic and 28-day ELS tests and the 21-day daphnid, Daphnia magna, life-cycle test.
The data sets included short-term chronic toxicity tests for the fathead minnow, Pimephales promelas, and the daphnid, Ceriodaphnia dubia.
For the tests to be acceptable, control survival in fathead minnow, Pimephales promelas, and the daphnid, Ceriodaphnia dubia, tests must be 80% or greater.
Reproduction data from the daphnid, Ceriodaphnia dubia, survival and reproduction test are analyzed using hypothesis testing or point estimation techniques according to the flowchart in Figure 2. In hypothesis testing, data from effluent concentrations that have significantly lower survival than the control, as determined by Fisher's Exact test, are not included in the hypothesis tests for reproductive effects.
The test organisms used in the procedures described in this manual are the fathead minnow, Pimephales promelas, the daphnid, Ceriodaphnia dubia, and the green alga, Selenastrum capricornutum.
