Description of key information
The toxic effects of the read across substance (CAS 83968-15-4) on the growth rate of Pseudomonas putida were determined in a study (BASF 1/90/0937/71/1, 1990) according to DIN 38412, Part 27 (Draft 1989) after short-term exposure of 30 min. After 30 minutes the EC50 of the surrogate test substance (CAS 83968-15-4) was determined to be 48 mg/L and the EC10 was determined to be 7 mg/L. All values refer to nominal concentration.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 48 mg/L
- EC10 or NOEC for microorganisms:
- 7 mg/L
Additional information
Supporting read-across study (BASF 1/90/0937/71/1, 1990)
The toxic effects of the read across substance (CAS 83968-15-4) on the growth rate of Pseudomonas putida were determined in a study (BASF AG, 1990) according to DIN 38412, Part 27 (Draft 1989) after short-term exposure of 30 min. The test was performed in nominal concentrations of 0 (control) 3.90, 7.81, 15.62, 31.25, 62.5, 125, 250, 500, 1000 and 2000 mg/L. No concentrations were measured. The test strain used of Pseudomonas putida came from die “Deutsche Sammlung von Mikroorganismen” in Goettingen, Germany. After 30 minutes the EC50 of the read across substance (CAS 83968-15-4) was determined to be 48 mg/L and the EC10 was determined to be 7 mg/L. All values refer to nominal concentration.
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.
