Description of key information
To investigate the effects of the test item on the growth of aquatic plants, the monocotyledonous species Lemna gibba was exposed to measured concentrations of the test item in the range of 0.440 to 10.8 mg/L for 7 days under static conditions. Testing was conducted in accordance with OECD guideline 221. The following effect values - based on frond number (growth rate) - were determined:
- NOEC (7 d) = 0.440 mg/L
- ErC10 (7 d) = 0.932 mg/L
- ErC50 (7 d) = 6.45 mg/L
Key value for chemical safety assessment
- EC50 for freshwater plants:
- 6.45 mg/L
- EC10 or NOEC for freshwater plants:
- 0.932 mg/L
