Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Black liquor showed only rather low acute toxicity on aquatic invertebrates in the available studies of high reliability. The studies with restricted reliability supported these findings. The tested sample contained 47.3 % water/52.7% dry solids.

Invertebrates:

EC50 (48 h) values for Daphnia magna were 685 mg/l (dwt.) (1300 mg/l (wwt.) and > 527 mg/l (dwt.) (>1000 mg/l (wwt.)) (n=2).

NOEC (48 h) values for Daphnia magna were 105 mg/l (dwt.) (200 mg/l (wwt.)) and 527 mg/l (dwt.) (1000 mg/l (wwt.) (n=2).
