Conclusions:

Ethyl bromide is not classified as toxic for aquatic invertebrates

Executive summary:

With an CE 50 24 h on dapnia magna well above 100 mg/l (limit value for 48 h), ethyl bromide is not classified as toxic for aquatic invertebrates.

The test material does not required classification according to Regulation 1272/2008.
