Key value for chemical safety assessment

Additional information

The acute toxicity of the test item to aquatic plants was investigated in a 7–day static test to Lemna minor, according to the OECD Guideline 221 (2006). The study was performed using 5 concentrations ranging from 4.6 to 100 mg/l. The frond number and the dry mass of each replicate were determined. Subsequently, Growth rate µ and the yield were determined from these parameters. As the measured concentrations lay between 85 % and 113 % of the nominal concentrations, the determination of the results was based on the nominal concentrations. All the validity criteria were met.

The ErC50 (7d) based on both frond number and dry mass was found to be > 100 mg/l.
