Description of key information

No acute toxicity (i.e. ErC50) was recorded up to the higher concentration reached in the test.

Key value for chemical safety assessment

Additional information

The effect of test item was assessed in Lemna gibba over an exposure period of 7 days, following the testing procedures outlined into the OECD guideline 221 on a Similar substance 01.

The 7-d ErC50, based on both frond number and dry weight, was determined to be higher than 0.69 mg/L. No acute toxicity (i.e. ErC50) was recorded up to the higher concentration reached in the test. The decrease of the measured concentrations during the experiment was due to the test substance adsorption to the lemna roots.
