Details on results:
Mortality rates of 7 - 33% were seen in the various groups, but this was not dose concentration related, with control group showing 21% mortality (marginally higher than recommended limit of 20%.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Remarks:
although control mortality of 21% was marginally higher than recommended limit of 20%
Conclusions:
Considered non-hazardous in sediments
