Results and discussion
Effect concentrations
- Duration:
- 30 d
- Dose descriptor:
- NOEC
- Effect conc.:
- 100 - 1 200 mg/kg soil dw
- Conc. based on:
- element
- Basis for effect:
- mortality
- Remarks:
- (No bioavailability correction possible as CEC is not given or can not be derived)
- Remarks on result:
- other: No bioavailability correction possible as CEC is not given or can not be derived.
Applicant's summary and conclusion
- Conclusions:
- Reliability: high quality NOEC value varied between 100 and 1,200 mg/kg for the endpoint mortality.
No bioavailability correction possible as CEC is not given or can not be derived. - Executive summary:
Copper sulfate toxicity in Octolasium cyaneum (Lumbricidae) was studied using different soil types. A strong positive correlation between toxicity (LC50 values) and percent carbon content of the soil could be detected, while no correlations with pH were noted.
