Key value for chemical safety assessment

Additional information

A 48 hour acute Daphnia toxicity study (conducted according to OECD Guideline Method No 202) was conducted, exposing Daphnia magna to phosphorus trichloride. The results of the study are based on nominal exposure concentrations and on test media without pH adjustment. The 24 and 48 hour EC50was 35.4 mg/L (geometric mean EC0/EC100). Under pH adjusted conditions no immobilisation was observed at a nominal concentration of 100 mg/L. Analytical determination of test substance concentration was not practical due to its rapid reaction with water and subsequent degradation.
