Description of key information

A study was carried out according to EU Method C.3 and OECD Guideline 201 (Alga, Growth Inhibition Test). Scenedesmus subspicatus, fresh water algal growth inhibition test with Nicotinamide. The 72-hour EC50 of growth inhibition and biomass was beyond the range of test concentrations applied in this test (> 1000 mg/L). The no observed effect concentration (NOEC) was 560 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L
EC10 or NOEC for freshwater algae:
560 mg/L
