Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The obtained estimated ChV (chronic value, 21 days) of 23.95 mg/L confirmed low toxicity of test substance to daphnid.
Executive summary:

The long-term toxicity value (Chronic Value, ChV) of Diallyl-2,2´-oxydiethyl dicarbonate for daphnids was determined by calculation. This calculation was performed by the computer program form US-EPA (EPIWIN software ECOSAR v1.00).

This program estimates the toxicity of chemicals discharged to water and predicts beside the acute (short-term) toxicity also the chronic (long-term or delayed) toxicity of a chemical.

As result a chronic value (ChV) of 23.95 mg/L for daphnid.
