Description of key information

EC50 (72-hour): >2.2 μg/L, growth rate and yield, Pseudokirchneriella subcapitata, read-across NOEC: ≥2.2 μg/L, growth rate and yield, Pseudokirchneriella subcapitata, read-across

Key value for chemical safety assessment

Additional information

No data are available with the registered substance. However, a 72-hour EC50 value of >2.2 μg/L and NOEC of ≥2.2 μg/L have been determined for the effects of the closely related substance L4 (CAS 141-62-8) on growth rate and yield of Pseudokirchneriella subcapitata. The results are expressed as geometric mean measured concentrations.
