Description of key information
In freshwater algae (Pseudokirchnerella subcapitata) , the 72-h ErC50 value is >100 mg/L and the 72-h NOEC value is 100 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
A GLP-compliant OECD 201 guideline study is available for toxicity in alga (Pseudokirchnerella subcapitata) for potassium tetrafluoroborate (NOTOX B.V., 2012). In this combined limit/range-finding test alga were exposed to 0.10, 1.0, 10 and 100 mg/L potassium tetrafluoroborate a blank control (test medium without test substance or other additives) and 1 or 2 replicates of each test concentration without algae for a period of 72 hours under static conditions. Analysis of the samples taken from 100 mg/L showed a measured concentration of 116 mg/L at the start of exposure. The concentration remained stable during the 72-hour test period (96-101% of initial). The 72-h ErC50 (growth rate) and EyC50 (biomass) values were >100 mg/L, the NOEC is 100 mg/L for both parameters (based on nominal concentrations).
