Description of key information

Reliable data for freshwater algal species have been generated in different laboratories, using different strains of the same algal species. Effect levels based on growth rate were situated between 61.2 and 366.2 mg Mo/L. The geometric mean of data that were generated with the most sensive strain was 74.3 mg Mo/L, and this value is put forward for the derivation of a freshwater PNEC in a weight of evidence approach.

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
74.3 mg/L
