Additional information

Short-term aquatic toxicity:

Reliable short-term toxicity tests for the registered substance are available for fish, algae and for daphnia.

One acute fish study is available. Fish were exposed for 96h in a static system. The LC50 was 1.95 mg/L (PARAD consortium, NOACK, 2010, D. Scheerbaum).

In the one available acute daphnia study, Daphnia Magna were exposed for 48h in a static system. The EC50 was 70.7 mg/L (PARAD consortium, NOACK, 2010, D. Scheerbaum).

In the one available algae study, the 72h-EC50 for growth rate was 2.2 mg/L (PARAD consortium, NOACK, 2010, D. Scheerbaum).

Long-term aquatic toxicity:

In Annex IX of Regulation (EC) No 1907/2006, it is laid down that chronic toxicity tests shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on fish. According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as dangerous according to Directive 67/548/EEC or Directive 1999/45/EC or is assessed to be a PBT or vPvB. The hazard assessment reveals neither a need to classify the substance as dangerous to the environment, nor that it is a PBT or vPvB substance, nor that there are any further indications that the substance may be hazardous to the environment. Therefore, a long-term toxicity study in aquatic organisms is not provided.

Toxicity to microorganisms:

A reliable study assessing the toxicity of the registered substance to microorganisms (OECD 209) is available. Based on the respiration rate, the EC20 was determined to be 507mg/l whereas the EC50 is > 1000 mg/l (PARAD consortium, NOACK, 2010, S. Fiebig).
