Description of key information
The 72h-ErC50 of phosphoryl trichloride exposed to Desmodesmus subspicatus in buffered medium was determined to be >100 mg/L with buffered test medium and 32.13 mg/L with non-buffered medium.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
Additional information
A 72 hour algal study (conducted according to EU Method C.3 (Algal Inhibition test)) was conducted, exposing phosphoryl trichloride to Desmodesmus subspicatus. The results of the study are based on nominal exposure concentrations and on test media with and without pH adjustment. Under pH adjusted conditions no inhibition of algal growth was observed at a nominal concentration of 100 mg/L. Without pH adjustment the 72 hour ErC50 was 32.12 mg/L with 95% confidence limits of 31.87 to 32.36 mg/L and the overall NOEC was 12.5 mg/L. Analytical monitoring of the achieved test substance concentrations was not possible due to the rapid degradation in aqueous environments.
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).
