Toxicity to fish:

The acute toxicity to fish of the test item was investigated in a test according to Directive 92/69/EEC. 10 test fish of the species Brachydanio rerio were exposed to the test item in a 96 h semi-static test with daily change of the test solution. The nominal tested concentrations were 1.0 and 100 mg/L. As the substance is sparingly soluble in water, the effect concentrations were calculated on basis of the nominal concentrations. The LC50 of the test item was estimated to be greater than 100 mgL (nominal concentration). (Henkel, 1997).

Long-term toxicity testing on fish is scientifically unjustified and thus not conducted.

Toxicity to aquatic invertebrates

The acute toxicity to daphnia of the test item was investigated in a limit test according to Directive OECD 202. The nominal tested concentrations was 100 mg/L. As the substance is sparingly soluble in water, the effect concentrations were calculated on basis of the nominal concentrations. The EC50 of the test item was estimated to be greater than 100 mgL (nominal concentration). (BASF, 2013).

Long-term toxicity testing on daphnia is scientifically unjustified and thus not conducted.

Toxicity to aquatic algae

The toxicity to algae of the test item was investigated in a limit test according to OECD 201. The nominal tested concentrations was 100 mg/L. As the substance is sparingly soluble in water, the effect concentrations were calculated on basis of the nominal concentrations. The EC10 of the test item was estimated to be equal or greater than 100 mgL (nominal concentration). (BASF, 2013).

Toxicity to microorganisms:

The toxicity of the test item to aquatic microorganisms was tested in the oxygen consumption inhibition test according to DIN 38412, Teil 27. A bacterial suspension of Pseudomonas putida was exposed to a nominal concentration of 10000 mg/L of the test item. The test item was directly weighed into the test vessel. The oxygen consumption inhibition was measured in relation to three blank samples. The maximum inhibition value of the test sample was less than 10 % in relation to the blank samples. No EC10 could be determined. Therefore, the EC0 of the test material was concluded to be 10000 mg/L (Henkel, 1997).
