Toxicity to the Aquatic Plant Lemna gibba in a Static Growth Inhibition Test 

Key value for chemical safety assessment

Additional information

The influence of the test item on the growth of the freshwater plant Lemna gibba was assessed in a static concentration-response test.

The 7-day EyC50was calculated to be> 100 mg test item/Lfor frond number and dry weight.

The 7-day ErC50was calculated to be> 100 mg test item/Lfor frond number and dry weight.

The 7-day NOEyC and the LOEyC were determined to be 10 and 32 mg test item/L for frond number and dry weight, respectively.

The 7-day NOErC and the LOErC were determined to be 10 and 32 mg test item/L for frond number and dry weight, respectively.
