Description of key information
The 18-h EC50 of 550 mg/L for Pseudomonas putida is used in the assessment.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 550 mg/L
Additional information
A GLP compliant growth inhibition study (Safepharm Laboratories Ltd., 1992) is available for potassium tetrafluoroborate. Pseudomonas putida was exposed to eleven test concentrations of potassium tetrafluoroborate (1.8 to 3,500 mg/L) for a period of 18 ± 2 hours under static conditions. Three replicates were considered at each of the test concentrations, for the control ten replicates were used. The growth inhibition was measured as turbidity. The 18-h EC50 value was 550 mg/L (based on nominal concentrations).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
