Any other information on results incl. tables

No mortality at 96 hours in the 0 and 1000 mg/l groups. 96 hrs-LL0 = 1000 mg/l, based on nominal loading rates. Only one concentration was tested in the limit test. The report states that water samples were taken at 0, 24, and 96 hours for analytical verification of test concentrations, but results of any analyses were not reported.
