Description of key information

Acute daphnia toxicity:

Acute toxicity of the test item was assessed on Daphnia magna in a 48-hour Acute Immobilisation test according to OECD 202. Based on the analytical results the test item was not expected to be stable for the duration of 48 hours in ISO Medium, therefore a semi-static test was performed using daily water renewal periods.

Based on the results of this study, the test item has no toxic effect on Daphnia magna up to at least the solubility limit of the test item in the test medium (0.13 mg/L measured). The 48-h NOEC was determined to be the saturation concentration, the EC50 results and the LOEC are higher than the saturation concentration (0.13 mg/L measured).

Algal growth inhibition

The effect of the test item was assessed on algal growth using the unicellular green alga Pseudokirchneriella subcapitata (Selenastrum capricornutum), over an exposure period of 72 hours and according to OECD 201. Cultures of Pseudokirchneriella subcapitata were exposed to the test item over several generations under defined conditions.

In the 72-h algal growth inhibition test on Pseudokirchneriella subcapitata with the test item, the 72-h EC50 value based on growth rate and yield was determined to be > 0.16 mg/L. The overall NOEC was determined to be 0.03 mg/L. The overall LOEC was determined to be 0.06 mg/L. The results are based on the measured concentrations.
