For the second interval, samples were collected from fresh test solutions within 30 min of test solution renewal at 48 hours and after 96 hours from all test vessels with surviving fish. Samples were taken from the middle of the test vessel using a glass pipette and were transported to the analytical laboratory in 50 mL glass ampoules on the day of sampling. The sample volume was 20 mL.
All samples were analyzed immediately upon receipt in the analytical laboratory (Analytical Chemistry Laboratory of Experimental Toxicology and Ecology, BASF SE, Ludwigshafen, Germany). - Vehicle:

- Details on test solutions:
- The test treatments were prepared separately for each test vessel. The test substance was homogenized by shaking the container before use. The test substance was weighed into a beaker. The defined volume of test water was added to the test vessel and an aliquot removed, mixed with the test substance in the beaker using a high shear mixer (Ultra Turrax, IKA Werke GmbH & Co. KG, Germany) and poured back into the test vessel. The test treatment was homogenized again with an ultra turrax. Fresh test solutions were prepared at the start of the experiment and after 48 h. All test treatments were visibly clear over the entire exposure period.

TEST CONCENTRATIONS
In a preliminary test (experimental conduct in accordance with GLP, but without a GLP status) using zebrafish, the 96-hour LC50 was estimated at 10 mg/L. Thus, the following concentrations were applied: 0 (control), 2.2, 4.6, 10, 22, 46, and 100 mg/L. - Duration:
- 96 h
- Dose descriptor:
- NOEC
- Effect conc.:
- 4.6 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Key result
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- 10.29 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Details on results:
- Since the mean measured concentrations of the test substance in the test solutions were within ±20% of the nominal concentrations, the effect concentration can be expressed relative to the nominal concentration for the evaluation of the test substance.
No mortality was observed in the test item concentrations up to and including 4.6 mg/L. 100% mortality occured in the concentrations 22, 46 and 100 mg/L.
Therefore, the 96-hour LC50 was determined to be 10.29 mg/L (based on nominal concentrations), 9.21 mg/L (based on mean measured concentrations). - Reported statistics and error estimates:
- For the statistical evaluation of the data and calculation of the LC50 the probit method (Finney,
1971) was used and performed with the commercial software "TOXRAT Professional 2.10”
(ToxRat Solutions GmbH, Alsdorf, Germany). - Validity criteria fulfilled:
- yes
- Conclusions:
- For the acute toxicity test with Danio rerio after 96 h a LC50 of 10.29 mg/L was obtained (based on the nominal concentration) for the test item.
All mean measured concentrations deviated less than 20% from the nominal concentration. Therefore, exposure conditions were consistent, and results can be expressed relative to the nominal concentrations. - Executive summary:
In a 96-hour acute toxicity study, zebrafish (Danio rerio) were exposed to IPGA at nominal concentrations of 0 (control), 2.2, 4.6, 10, 22, 46, and 100 mg/L, corresponding to mean measured concentrations of 0 (control), 2.0, 4.17, 8.96, 19.4, 42.3, 95.4 mg/L under static/renewal conditions in accordance with the OECD 203 test guideline. The water pH, temperature and dissolved oxygen were within acceptable guideline specifications.
No mortality was observed in the test item concentrations up to and including 4.6 mg/L. 100% mortality occured in the concentrations 22, 46 and 100 mg/L.
Therefore, the 96-hour LC50 was calculated as 10.29 mg/L (based on nominal concentrations), 9.21 mg/L (based on mean measured concentrations).
