Description of key information
In a 48h acute toxicity study, Daphnia magna (STRAUS) were exposed to test item under static conditions. The 48h-EC50 was greater than 100 mg/L.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Dose descriptor:
- EC50
- Effect concentration:
- 100 mg/L
Additional information
In the acute immobilization test with Daphnia magna (STRAUS) the effects of the limit concentration 100 mg/L of the test item were determined according to OECD 202 (2004). The limit test was conducted under static conditions over a period of 48 h. 20 test organisms each were exposed to the limit concentration and the control. The limit concentration and the control media after 0 h (new media) without daphnia were analytically verified via DOC analysis according to DIN EN 1484. All effect values are based on the nominal test item concentration. Water quality parameters such as pH and dissolved oxygen concentration, measured at 0 and 48 h were determined to be within acceptable limits. The validity criteria of the test guideline were fulfilled.
Based on the nominal test item concentration, the EC50 (48h) was greater than 100 mg/L and the NOEC (48h) was 100 mg/L.
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.
