Test conditions
- Test temperature:
- 20.0 - 20.1 ºC
- pH:
- Start: 6.60 - 7.48
End: 7.49 - 7.50 - Dissolved oxygen:
- test start: 6.84 – 7.52 mg O2/L
Test end: 6.63 – 6.43 mg O2/L - Nominal and measured concentrations:
- 100 mg/L
- Details on test conditions:
- The test was performed in glass beakers filled with 40 mL of test medium. The test vessels were covered with glass plates to reduce the loss of water and to avoid dust entry into test solutions.
The test vessels were labelled with the internal study number and all necessary additional information to ensure unmistakable identification.
For the tested concentration and for the negative control, group of 20 daphnids were used divided into four replicates of five daphnids each. The daphnids were randomly distributed to the test vessels at test initiation. The daphnids loading rate was about 8 mL per one daphnid (5 daphnids for 40 mL, according to OECD guideline 202, 2004).
Temperature:
The incubation temperature was continuously monitored during the course of the study by a PT100 probe installed in the environmental test chamber. It was in the range 20.0 – 20.1°C with a mean value of 20.0 °C and a standard deviation of 0.02 °C. The temperature range provided by OECD guideline 202, 2004 is 20 ± 2°C. The temperature values during the test were within the provided range and did not vary more than 1°C during the test period.
