Description of key information

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:
70.81 µg/kg soil dw

Additional information

The results of this study show neither lethal nor sublethal effects of 1,2,4-triazole on earthworms E. fetida. Mortality, growth, reproduction and feeding activity of the earthworms were not affected by exposing them to 7.08 µg/kg, 35.41 µg/kg and 70.81 µg/kg soil of 1,2,4-triazole.

Consequently the conclusion of this study is that 1,2,4-triazole does not cause lethal or sublethal effects on earthworms E. fetida if applied in amounts up to 70.81 µg/kg soil.

The NOEC found in this study was 70.81 µg/kg soil, the highest concentration tested.
