Description of key information

The 48h-EC50 value based on nominal concentrations was 602 mg/L. 

Key value for chemical safety assessment

Additional information

Two short-term studies, valid without restrictions, with invertebrates are available.

The final test (key study) was conducted under semi-static (24 hour renewa1) conditions (Jenkins, 1989). Daphnia were exposed to five concentrations in the range 100 to 1000 mg/L.

The pH of each was adjusted to approx. 7.0 before the addition of the daphnids. The 48h-EC50 value based on nominal concentrations was estimated to be 602 mg/L. This value is supported by a static test with Daphnia magna (Jenkins, 1991), which gave an 48h-EC50 of 687 mg/L at a pH of approx. 7.0.
