Key value for chemical safety assessment

Additional information

The results from short-term toxicity tests on fish, Daphnia and algae demonstrate that algae are the most sensitive trophic level tested. Therefore, it may be concluded that results from a long-term test in fish would not reveal a greater hazard than already determined by the available data. Therefore, and for reasons of animal welfare, a chronic test on fish is not provided.

In Annex IX of Regulation (EC) No 1907/2006, it is laid down that long-term toxicity to fish 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.

1 -ethylpiperidine is not a PBT or vPvB substance. The ACR approach according to ECETOC (2003, Report no. 91) results in NOECs greater than 1 mg/L based on the effect data for neutralised test solutions.

Based on the available acute data, the substance is not to be classified as dangerous to the environment and it is not a PBT of vPvB substance. No further information indicate that the substance may be hazardous to the environment. With regard to the results of the ACR approach and for reasons of animal welfare, a long-term study on the toxicity to fish is not provided.
