Description of key information

Activated sludge respiration inhibition test with SR-245

Key value for chemical safety assessment

EC50 for microorganisms:
1 µg/L
EC10 or NOEC for microorganisms:
1 µg/L

Additional information

The results of LC50> 100mg/L NOEC≥ 100mg/L indicate that under the conditions of the present test SR-245 was not toxic to waste water bacteria at a concentration of ca. 100 mg/L although this study was performed above water solubility level. The value of 1µg/l is taken as the actual water solubility value of the substance.

The substance water solubility value of 1ug/l is taken as a worst case scenario for PNEC calculation.
