Constituent 1
- Specific details on test material used for the study:
- Batch: W19011506
Purity: Approximately 30% active in water*
Physical State/Appearance: Opaque beige viscous liquid
Expiry Date: 18 January 2021
Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- Water samples were taken from the control and test group, from fresh and old media
throughout the 96-Hour test period, for quantitative analysis. All samples were stored frozen
prior to analysis. Duplicate samples were taken and stored frozen for further analysis if
necessary.
The concentration and stability of the test item in the test preparations were verified by
chemical analysis at 0, 24, 48, 72 and 96 hours
Test solutions
- Vehicle:
- no
- Details on test solutions:
- A nominal amount of test item (3334 mg) was added to the surface of 10 liters of test water
and stirred by magnetic stirrer using a stirring rate such that a vortex was formed to give a
dimple at the water surface. The stirring was stopped after 24 hours and the test dispersion
removed by mid-depth siphoning using a glass syphon.
Test organisms
- Details on test organisms:
- The definitive test was carried out using juvenile fathead minnow (Pimephales promelas).
Fish were bred and maintained in-house since 16 December 2019. Fish were maintained in a
glass tank with a "single pass" water renewal system. Fish were acclimatized to test
conditions from 20 January 2020 to 27 January 2020.
Study design
- Test type:
- static
- Water media type:
- freshwater
- Remarks:
- The test water was the same as that used to maintain the stock fish. Laboratory tap water was dechlorinated by passage through an activated carbon filter (Purite Series 500) and partly softened (Elga Nimbus 1248D Duplex Water Softener) giving water with a
- Limit test:
- yes
- Total exposure duration:
- 96 h
- Post exposure observation period:
- 0
Test conditions
- Hardness:
- 140 mg/L as CaCO3
- Test temperature:
- 20 °C to 22 °C
- pH:
- 7.7-8.1
- Dissolved oxygen:
- 6.9-9.9
- Nominal and measured concentrations:
- Analysis for ion 789 of the freshly prepared test media at 0, 24, 48 and 72 hours showed measured test concentrations of 23.2, 20.4, 16.8 and 20.4 mg ai/L
respectively and of the corresponding old or expired media at 24, 48, 72 and 96 hours showed
measured test concentrations of 18.6, 18.4, 18.2 and 19.3 mg ai/L respectively.
Analysis for ion 443 of the freshly prepared test media at 0, 24, 48 and 72 hours showed measured test concentrations of 11.8, 14.8, 8.2 and 9.7 mg ai/L respectively
and of the corresponding old or expired media at 24, 48, 72 and 96 hours showed measured
test concentrations of 10.0, 10.2, 9.5 and 9.7 mg ai/L respectively.
As values for both ions were not within 80 to 120% of nominal, it was considered appropriate
to calculate the results based on the geometric mean measured test concentrations only in
order to give a “worst case” analysis of the data. The geometric mean measured test
concentrations were determined to be 18.68 mg ai/L for ion 789 and 10.42 mg ai/L for
ion 443.

- Details on results:
- Exposure of fathead minnow to the test item based on the geometric mean measured test
concentrations gave an LC50 value of greater than 18.69 mg ai/L for ion 789 and 10.42
mg ai/L for ion 443. The No Observed Effect Concentration (NOEC) was 18.69 mg ai/L for
ion 789 and 10.42 mg ai/L for ion 443.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- The test was considered to be valid given that none of the control fish died or showed signs of stress during the test and that the oxygen concentration at the end of the test was ≥60% of ASV (5.2 mg O2/L) in the control and test vessels.
