Description of key information
The test was conducted for 7 days at 23 to 24 °C, under continuous illumination at 600 to 850 footcandles (6500 to 9100 lux). The dilution water used was 20X Algal Assay Procedure (AAP) medium.
The nominal concentrations used were 6.3, 13, 25, 50 and 100 mg/L which correspond to mean measured concentrations of 5.7, 12, 23, 46 and 93 mg/L.
The 7 day EC50 for growth rate, biomass and cell density is >93 mg/L (mean measured), this corresponds to a nominal concentration of >100 mg/L. The 7 day NOEC is 93 mg/L (100 mg/L nominal).
Additional testing to further define the EC50 values was not performed since the highest nominal concentration tested was equivalent to the maximum concentration required by the U.S. EPA and OECD guidelines (100 mg/L).
Key value for chemical safety assessment
- EC10 or NOEC for freshwater plants:
- 93 mg/L
Additional information
The acute toxicity of the test material and water to the Duckweed, Lemna gibba was investigated during a study conducted at Springborn Smithers Laboratories. The test was performed from 24 February to 6 March 2006 and was conducted according to OECD Guideline 221 (Lemna sp. Growth Inhibition test).
This study is presented as the key information as the reliability rating for this study is 1, according to the criteria of Klimisch, 1997.
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.
