Description of key information

The 62.5 - 1000 mg/kg groups showed no effect in comparison with the control. The LC0 and LC50 of Indigo aus Indigo-Küpe after 14 days were > 1000 mg/kg dry weight of artificial soil under the conditions of this test.

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
1 000 mg/kg soil dw
Long-term EC10, LC10 or NOEC for soil macroorganisms:
1 000 mg/kg soil dw

Additional information

The toxicity of Indigo aus Indigo-Küpe to earthworms (Eisenia foetida) was tested in an artificial soil test for 14 days.

The concentrations tested were 62.5, 125, 250, 500, and 1000 mg/kg (dry weight of artificial soil) and a control.

The following mortality values were determined after 7 days after 14 days:

LC0: >1000 mg/kg soil

LC50: >1000 mg/kg soil

LC100: >1000 mg/kg soil

In the control group no effects were observed. The 62.5 - 1000 mg/kg groups showed no effect in comparison with the control
