Short-term toxicity to fish

The acute toxicity of the test substance to Zebra fish (Danio rerio) was determined by static test according to OECD 203 under GLP conditions. The LC50 was determined to be 7.5 mg/L (reference 6.1.1-1).

Short-term toxicity to aquatic invertebrates

The EC50 (48h) of the test item to Daphnia magna was determined to be 5.1 mg/L (reference 6.1.3-1) according to OECD 202 under GLP conditions.

Toxicity to aquatic algae and cyanobacteria

The test substance was tested to Desmodesmus subspicatus in a closed static test system according to OECD 201 (1984). Under the given conditions of this study (reference 6.1.5-1) the 72 h ErC50 value was determined to be 18.4 mg/L and the NOEC was determined to be < 10 mg/L.

Toxicity to microorganisms

The toxic effects of the test substance on the oxygen consumption rate of aerobic micro-organisms (activated sludge) after of 180 min was determined according to the OECD 209 (1984), (reference 6.1.7-1). The EC50 was determined to be 17.3 mg/L and the NOEC was determined to be 10 mg/L.
