Description of key information
ErC50(72h) = 480 mg/L for Pseudokirchneriella subcapitata (OECD 201)
NOEC(72h) = 24 mg/L
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 480 mg/L
- EC10 or NOEC for freshwater algae:
- 24 mg/L
Additional information
There is one study with algae available for 2-amino-1,3-propanediol (APD), which was used as key study for the assessment. The study was conducted according the OECD guideline 201 and GLP (Soucy, 2011). The test organism Pseudokirchneriella subcapitata was exposed to APD in a static system for 72 hours, at the test concentrations 11, 24, 55, 150, 390, 980 mg a.i./L. An EC50 of 480 mg/L and a NOEC of 24 mg/L were obtained, based on growth rate.
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.
