Description of key information
Additional information
Short-term toxicity to fish
The lethal concentration (LC50) for piperazine adipate for Oncorhynchus mykiss at 96 hours is estimated to be 134.66 mg/L. Based on this value it can be concluded that piperazine adipate is not toxic to aquatic environment based the criteria given by CLP regulation.
Long-term toxicity to fish
According to column I of annex IX , Long-term toxicity testing on fish need not to be conducted as information on short term toxicity effect is already provided as part of Annex VIII requirements. Therefore this study was considered to be waived.
Short-term toxicity to aquatic invertebrates
The effective concentration (EC50) for piperazine adipate for Daphnia magna at 48 hours is estimated to be 201.06 mg/L for intoxication effect. Based on this value it can be concluded that piperazine adipate is not toxic to aquatic environment based the criteria given by CLP regulation.
Long-term toxicity to aquatic invertebrates
According to column I of annex IX ; Long-term toxicity testing on invertebrate (species : Daphnia) need not to be conducted as information on short term toxicity to aquatic invertebrates is already provided as a part of Annex VII requirements. Therefore this study was considered for waiver.
Toxicity to aquatic algae and cyanobacteria
The effective concentration (EC50) for piperazine adipate for Pseudokirchneriella subcapitata at 72 hours is estimated to be 119.68 mg/L for effect on growth. Based on this value it can be concluded that piperazine adipate is not toxic to aquatic environment based the criteria given by CLP regulation.
Toxicity to microorganisms
The growth inhibition concentration (IGC50) for piperazine adipate for Tetrahymena pyriformis at 48 hours is estimated to be 916.19 mg/L for effect on growth. Based on this value it can be concluded that piperazine adipate is not toxic to aquatic environment based the criteria given by CLP regulation
