Description of key information

Study conducted in accordance with EU method C3 (Algal inhbition test). Exposure of algae to the test substance for 96 hours resulted in a median effective concentration (EC50) of 280 mg/L NBPT, with a 95 percent confidence interval of 200 - 400 mg/L. The 96 hour no observed effect concentration is 75 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
280 mg/L
EC10 or NOEC for freshwater algae:
75 mg/L
