At the start and the end of the test, the
analytically determined concentration of the test substance in the test
medium was 132 and 105 mg/L, respectively. The mean measured
concentration of the test substance was 119 mg/L. All biological results
were based on the nominal concentration of the test substance of 100
At the beginning and the end of the test
period, the dissolved oxygen concentration in the test medium and the
control was at least 7.2 mg/L. The pH of the test medium and the control
was between 7.8 and 7.9. The water temperature was 20 deg C at the start
and the end of the test.
The study of Bätscher (2017), investigating the acute toxicity
of T002675 in Daphnia magna according to OECD guideline 202, was
considered as the key study for endpoint coverage. An EC50 > 119 mg/L
(based on analytically test concentrations) was found after an
exposure of 48 hours in a static limit test in freshwater. Based on
the results it can be concluded that T002675 is not harmful to aquatic
