Description of key information

Algae were exposed to 0 and 100 mg/L test substance during 72 hours. No effects on growth rate and biomass were found. The analyses for accuracy of preparation at the maximum concentration attainable showed that the average measured concentration at a loading rate of 100 mg/L was 0.12 mg/L. The The ECr50 for algae is > 100 mg/L as loading rate and the NOEC is 100 mg/L as loading rate (Harlan 2012f).

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
0.12 mg/L
