After 24 hours of exposure no immobilisation was observed in the
control, solvent control and up to and including 12.5 mg/L. 50 % of the
daphnids were immobile in the test item concentration of 25.0
mg/L. 90 % immobilisation was observed at the highest test item
concentration of 50.0 mg/L.
In the test item concentrations of 25.0 and 50.0 mg/L fine oil droplets
were observed at the surface of the test item solution. The daphnids did
pend at the surface and were partly sticky.
After 48 hours of exposure no immobilisation was observed in the
control, solvent control and all test item concentrations up to and
including 6.25 mg/L. No immobilisation higher than the allowed
control immobilisation was observed 12.5 mg/L. 75 % immobilisation was
observed at 25.0 mg/L. In the highest test item concentration of 50.0
mg/L all daphnids were immobile.
In the test item concentrations of 3.13 and 6.25 mg/L the daphnids did
partly pend to the surface of the test item solutions. In the test item
concentrations of 12.5 mg/L and above, all daphnids did
pend at the surface of the test item solutions. Additionally the same
observations were made in the test item concentrations of 25.0 and 50.0
mg/L as after 24 hours.
The initial measured content of VSV16 was between 11 and 143 % of
nominal and the aged measured content was between 3 and 25 % of nominal.
Therefore the toxicological endpoints were
evaluated using nominal and actual (based on the geometric mean of each
concentration level) concentrations.
