The acute toxicity of the substance to fish (Danio rerio) was tested in a static test. After 96 hours of exposure, a LC0 of ≥100 mg/L and a LC100 of >100 mg/L were determined. A LC50 of >100 mg/L was calculated.
"should read LC50 > 100 mg/L"
The study was conducted in accordance with Council Regulation (EC) No
440/2008, Method C.1 'Acute toxicity for Fish' (2008) which is in most
parts equivalent to the OECD Guideline for Testing of Chemicals No. 203
'Fish, Acute Toxicity Test' (1992).
A group of seven fish of the recommended size was exposed to a limit
test concentration of nominally 100 mg/L of the substance dissolved in
dilution water. Auxiliary used to prepare the test medium was a magnetic
stirrer. Observations were made on the number of dead fish and the
incidence of sub-lethal effects after 2, 24, 48, 72 and 96 hours of
exposure. No toxic effects against fish were observed at a limit test
concentration of 100 mg/L under exposure conditions. All results are
expressed in terms of nominal concentrations. Effective concentrations
correspond to 95.5 % of nominal values at 0 hours and to 94.6 % of
nominal values at 96 hours. The substance does not have a definite or
unique structure and consists of several components. No information
about the correlation between molecular weight and the structural
formula of the test item are available.
This toxicity study is classified acceptable and satisfies the guideline
requirements for acute toxicity to fish.
