A 10 mg/l nominal test substance concentration was prepared
by stirring for 72 hours. Measured concentrations in
centrifuged samples at 0h and 48h were < limit of detection
(0.03 mg/l). Analysis of non-centrifuged samples gave
variable results - 2.7, 2.7, 2.5 mg/l at 0h and 0.24, 0.41,
0.72 mg/l at 48h. No effects were observed so it can be
assumed that the test substance shows no effects up to its
limit of solubility.
