Additional information

Acute toxicity to fish

The 96 -h LC50 (Onchorhynchus mykiss) was determined to be > 100 mg/L (OECD 203, ASTA Medica AG, 1998). Therefore, the substance is with high probability acutely not harmful to fish.

Acute toxicity to aquatic invertebrates

The 48 -h EC50 (Daphnia magna) was determined to be > 100 mg/L (OECD 202, ASTA Medica AG, 1998). Therefore, the substance is with high probability acutely not harmful to aquatic invertebrates.

Toxicity to algae and cyanobacteria

The 72 -h ErC50 (Desmodesmus subspicatus) was determined to be > 100 mg/L (OECD 201, BASF AG, 2004). The ErC10 is also above the highest tested concentration of 100 mg/L. Therefore, the substance is with high probability acutely not harmful to algae.

Toxicity to microorganisms

The 180 -min EC20 (activated sludge, domestic) was determined to be > 1000 mg/L (OECD 209, BASF AG, 2004). Additionally, the 16 -h ErC10 (Pseudomonas putida) was determined at 7700 mg/L (ASTA Medica AG, 1993). Therefore, no inhibition of the degradation activity of activated sludge is anticipated if the substance is introduced in appropriately low concentrations.
