Additional information

Toxicity to fish

The acute toxicity was investigated in freshwater fish rainbow trout. The 96h-LC50 was 7.10 mg/L. A waiver is proposed for long-term toxicity to fish, on exposure grounds.

Toxicity to aquatic invertebrates

The acute toxicity was investigated in Daphnia. The 48h-EC50 corresponds with 11.96 mg/L based on the geometric means of the concentration.

Toxicity to algae

The toxicity was investigated in Pseudokirchneriella subcapitata over a period of 72 hour.

The EC50 for growth rate reduction (72 hours) is 11.70 mg/L based on the geometric means of the concentration.

NOErC (growth rate) = 0.74 mg/L

Toxicity to micro-organisms

The respiration rates of samples of activated sludge fed with synthetic sewage were measured in an enclosed cell containing an oxygen electrode after a contact time of 3 hours according to OECD 209 Guideline (2010).

EC50-3h=202.7 mg/L(124.7 – 340.4 mg/L)
