Listed below are the test validity criteria and the results for this particular test. Criteria from the guideline are presented numerically, followed by our results noted with an asterisk.
1. The difference of extremes of replicate values of the removal of the test chemical at the plateau, at the end of the test or at the end of the 10-day window, as appropriate, is less than 20% and if the percentage degradation of the reference compound has reached the pass levels by day 14.
*At the end of the test (Day 28) replicate values varied by 7.9%, thus not exceeding 20%. The reference substance degradation reached the required 60% degradation by Day 7.
2. If in a toxicity test, containing both the test substance and a reference compound, less than 35% degradation (based on total DOC) or less than 25% (based on total ThOD or ThCO2) occurred within 14 days, the test substance can be assumed to be inhibitory.
*The toxicity control, containing both the test substance and reference compound, did not achieve 25% by day 14. Therefore, the test substance may be assumed to be inhibitory.
3. The oxygen uptake of the inoculum blank is normally 20-30 mg O2/L and should not be greater than 60 mg/L in 28 days.
*The mean oxygen uptake of the inoculum blanks was 22.1 mg O2/L, and was not greater than 60 mg/L in the 28 days.
4. If the pH value is outside the range 6-8.5 and the oxygen consumption by the test substance is less than 60%, the test should be repeated with a lower concentration of test substance.
*At test initiation the pH values were 7.50 in Test Replicate A and 7.50 in Test Replicate B. At the end of the test, the pH values were 8.97 in Test Replicate A and 8.31 in Test Replicate B.
The isophoronediamine-cresyl glcidyl ether adduct did not reach pass levels for biodegradation within the 28-day period of the test, indicating that it is not readily biodegradable. The toxicity control treatment reached pass levels for biodegradation by day 7, indicating that the test substance is not inhibitory.
