Description of key information
Acutely harmful to Desmodesmus subspicatus.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 24.6 mg/L
- EC10 or NOEC for freshwater algae:
- 1.9 mg/L
Additional information
The toxicity of 1 -Ethylpiperidine (CAS 766 -09 -6) to the test organism Desmodesmus subspicatus tested according to the OECD Guideline 201 (Alga Growth Inhibition Test). The obtained effect concentrations [ErC10 (72 hr) = 8.9 mg/L; ErC50 (72 hr) =24.6 mg/L] were calculated using probit analyses. The NOEC [NOEC (72 hr) = 1.9 mg/L] was determined by a multisample comparison (according to DUNNETT 1955, 1964)[BASF AG; study no.: 2006/0006/09].
Based on the effect value ErC50 (72 hr) = 24.6 mg/L the test substance is acutely harmful to aquatic organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
