Study design

Total exposure duration:
48 h
Post exposure observation period:
not applicable

Test conditions

Hardness:
250 mg/L expressed as CaCO3
Test temperature:
Blank control during the study: 19.6 - 20.4°C
pH:
At t=0h and t=48h
Control: 7.8 - 7.8
Test samples: 7.8 - 7.9
Dissolved oxygen:
At t=0h and t=48h [mg/L]
Control: 7.8 - 8.0
Test samples: 8.2 - 8.5
Salinity:
not applicable
Nominal and measured concentrations:
As the submission substance was insoluble in water (< 10µg/L), analytical verification was impossible due to sensitivity limitations. Therefore, in a limit test the nominal substance concentration of 100 mg/L in test medium was applied after filtration through a 0.45 µm membrane filter.
