Description of key information
Based on the results of one OECD202 test with Daphnia magna, the EC50 of the test item after 48h of exposure was greater than 100 mg/L.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 100 mg/L
Additional information
For this endpoint one test is available. In this acute immobilization test with Daphnia magna (STRAUS), the effects of the limit concentration of 100 mg/L of the test item were determined according to OECD 202 (2004).
The study was conducted under static conditions over a period of 48 hours in a closed system (sealed glass flasks) without headspace. The limit concentration of 100 mg/L prepared was visually clear throughout the exposure period.
Twenty daphnids (divided into 4 replicates with 5 daphnids each) were exposed to the limit concentration and the control.
The validity criteria of the test guideline were fulfilled.
The EC10, EC50 and EC100 values (based on the nominal concentration of the test item) were all greater than 100 mg/L both after 24 and 48 hours. As key value the lowest concentration from the range was selected: 100 mg/L.
