Description of key information

No Observed Effect Concentration (NOEC) for mortality, growth, reproduction and feeding activity of the earthworm Eisenia fetida was determined to be 1000 mg test item/kg soil, i.e. the highest concentration tested.

Key value for chemical safety assessment

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

Additional information

A 56-day test in treated artificial soil prepared according to OECD 222 (5% peat only) is available. Different concentrations of the test item were incorporated into the soil in 6 treatment groups (5 test item concentrations, control)and 4 replicates for the test item treatments and 8 replicates for the control with 10 worms each (Ganßmann, 2013). Assessment of adult worm mortality, behavioural effects and biomass development was carried out after 28 days exposure of adult worms in treated artificial soil. Reproduction rate (number of offspring) was assessed after additional 28 days (assessed 56 days after application). No Observed Effect Concentration (NOEC) for mortality, growth, reproduction and feeding activity of the earthworm Eisenia fetida was determined to be 1000 mg test item/kg soil, i.e. the highest concentration tested.
