Additional information

No experimental data are available for RAV 7MC (EC 700-742-1). For justification of the intended read-across approach of Diallyl-2,2 ยด-oxydiethyl dicarbonate (EC 205 -528 -7) toReaction mass of 2,2'-oxydiethanol and 2,2-dimethylpropane-1,3-diol and diallyl 2,2'-oxydiethyl dicarbonate and diallyl carbonate and pentaerythritol' (EC 700 -742 -1), please refer to the overall summary of aquatic toxicity test results.

The freshwater study was performed with Daphnia magna under static conditions and in accordance with the US-EPA method number 660/3-75-009 (Suprenant and Le Blanc, 1982). An LC50 of 18 mg/L was determined after test duration of 48 hours.

The static marine toxicity test was conducted according to le internal procedures of the EG&G Bionomics Marine Research Laboratory (BMRL) on mysid shrimp (Mysidopsis bahia) as test species (Scott Ward, 1982). The LC50(96h) was determined to be 70.7 mg/L with 95 % confidence limits of 55.6 โ€“ 77.6 mg/L.
