EC number: 413-110-2
CAS number: 135861-56-2
The 96-Hour LC50 was determined to be > 0.10 mg/L. Correspondingly the No Observed Effect Concentration was ≥ 0.10 mg/L.
A study was performed to assess the acute toxicity of the test material
to rain bow trout (Oncorhynchus mykiss). The method followed that
described in the OECD Guidelines for Testing of Chemicals No 203, "Fish,
Acute Toxicity Test" referenced as Method C.1 of Commission Directive
Following a preliminary range-finding study and pre-study testing fish
were exposed, in 2 groups of 10, to an aqueous dispersion of the test
material, at a single concentration of 0.10 mg/L for a period of 96 h
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 h after the start of exposure and then daily
throughout the study until termination after 96 h.
The 96-Hour LC50 for the test material to rainbow trout (Oncorhynchus
mykiss), based on nominal test concentrations was > 0.10 mg/L and
correspondingly the No Observed Effect Concentration was ≥ to
The test concentration of 0.10 mg/L was the highest attainable test
concentration due to the limited solubility of the test material in
water and auxiliary solvent, and having due regard for the amount of
auxiliary solvent permitted in the test under the OECD Guidelines.
Analysis of the test solutions at 0, 24 and 96 h showed the measured
test concentrations to be in excess of the required 80 % of nominal test
concentrations and so the results are based on nominal test
