Description of key information

IC50 of NaCl  at 96h to Lemna was determined for comparison and found to be 6870 mg/l (6.87g/L)

Key value for chemical safety assessment

EC50 for freshwater plants:
6 870 mg/L

Additional information

Effect of NaCl on the number of fronds at different times (24, 48, 72 and 96h) showed differences in their replication at 96h. The sensitivity of Lemna to sodium chloride, the reference substance, at concentrations of 0, 2000, 4000, 6000, 7000 and 8000 mg/L (0, 2, 4, 6, 7 and 8g/L), was determined for comparison and resulted in an IC50 of 6870 mg/l (6.87g/L)
