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.
