A study was performed
to assess the acute toxicity of the test material to rainbow trout
(Oncorhynchus mykiss). This key aquatic toxicity study was assigned
reliability rating of 1 (reliable without restriction) and the results
are considered valid.
Following a preliminary
range-finding test fish were exposed, in two groups of seven, to an
aqueous solution of the test material, at a single concentration of 100
mg/L for a period of 96 hours at a temperature of approximately 14 C
under semi-static test conditions. The number of mortalities and any
sub-lethal effects of exposure in each test and control vessel were
determined 3 and
6 hours after the start of exposure and then daily throughout the test
until termination after 96 hours.
The 96-Hour LC50 based
on nominal test concentrations was greater than 100 mg/L and
correspondingly the No Observed Effect Concentration was 100 mg/L. It
was considered unnecessary and unrealistic to test at concentrations in
excess of 100 mg/L.
Analysis of the test
preparations at 0, 24 and 96 hours showed measured test concentrations
to range from 96% to 99% of nominal and so the results are based on
nominal test concentrations only.
