Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
DecaBDE was not toxic to the sediment organism, L. varigaetus.
Executive summary:

The NOEC concentration of DecaBDE in 2% TOC sediment to the oligochaete, L. varigaetus, was 5000 mg/kg dry weight sediment based on a lack of effects on survival/reproduction and growth.
