Comments:
LC100 at 96 hours (mg/l) >limit of solubility


The toxicity results are based on the centrifuged mean
measured exposure concentrations of the test substance


The post-centrifugation mean measured concentration of the
test substance was 0.41 mg/l (4% of the nominal exposure
concentration)


Limit test performed at maximum achievable concentration.
Solutions stirred for 24 hours prior to testing to achieve
maximum dissolution. No toxicity observed.
