Therefore, results of different diets can be considered roughly equivalent to five replications of the same diet.

- Principles of method if other than guideline:
- Initial experiments (Phase I) were designed to determine the effects of LAS on the structure and function of model ecosystem communities. Each test concentration consisted of duplicate 19-L glass aquaria containing 2.5 cm of natural lake sediment and several trophic levels (bacteria, algae, macrophytes, macroinvertebrates, and bluegill sunfish). Dilution water was carbon and reverse-osmosis filtered well water. Four nominal concentrations were delivered to duplicate chambers by a modified Mount and Brungs proportional diluter. Fish were screened from access to invertebrates with a stainless steel screen. In Phase II, conditions were similar except that the model ecosystem aquaria were treated with LAS in sewage effluent (supplied from a CAS unit) to more closely simulate actual receiving water conditions.

- Chronic toxicity values were developed for Daphnia magna with six surfactants and a detergent builder, each selected on the basis of previously existing chronic fish test data.
Predictive correlations were examined for testing end points between 21-d Daphnia chronics and 1-yr fish chronics to provide a short-term alternative chronic test species while developing toxicity data for an intermediate trophic level species. For the detergent materials tested, a strong correlation (r0.98) exists between = Daphnia and fish no-effect concentrations. A replacement term, NOEC (No observed effect concentration), is suggested to clarify interpretive ambiguities associated with the definition of the MATC (maximum acceptable toxicant concentration) value. - GLP compliance:
