In an earthworm reproduction and growth study with 400160 the No Observed Effect Concentration (NOEC) for mortality, growth, reproduction and feeding activity of the earthworm Eisenia fetida was determined to be higher than or equal 1000 mg test item/kg soil, i.e. the highest concentration tested.
The effects on reproduction and growth of earthworms (Eisenia fetida) in
artificial soil were determined with test item 400160 with an OECD 222
All study validity criteria were met. No mortality was observed in any
treatment group. The body weight changes of the earthworms after 4 weeks
exposure to 400160 were not statistically significantly different
compared to the control up to and including the highest test
concentration of 1000 mg test item/kg soil (Williams t-test, α = 0.05,
two-sided). The reproduction rates were not statistically significantly
different compared to the control up to and including the highest test
concentration of 1000 mg test item/kg soil (Dunnetts t-test, α = 0.05,
one-sided smaller). No behavioural abnormalities were observed in any of
the treatment groups. The feeding activity in all the treated groups was
comparable to the control.
