Description of key information
The toxic effect of the test item L-glutamine to Algae was assessed in a growth inhibition test. L-Glutamine was found not to inhibit the growth of the freshwater green alga Desmodesmus subspicatus after 72 hours. The NOEC-value of the test item for both inhibition of growth rate and inhibition of yield after 72 hours was 100 mg/L. The EC50-values of the test item for both inhibition of growth rate (ErC50) and yield (EyC50) after 72 hours were > 100 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
The toxic effect of the test item L-glutamine to Algae was assessed in a growth inhibition test. L-Glutamine was found not to inhibit the growth of the freshwater green alga Desmodesmus subspicatus after 72 hours. The NOEC-value of the test item for both inhibition of growth rate and inhibition of yield after 72 hours was 100 mg/L. The EC50-values of the test item for both inhibition of growth rate (ErC50) and yield (EyC50) after 72 hours were > 100 mg/L. A slight stimulation on the yield was observed.
All effect levels are given based on the nominal limit concentration of the test item L-Glutamine.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
