Description of key information

Three studies are available on the toxicity of Nitroethane to Daphnia. The acute toxicity at 48h was evaluated as an additional endpoint of the chronic toxicity study on Daphnia magna.  Two further studies are available, however provide limited or no information on the exposure levels, their analytical verification and effects observed, thus were disregarded from the assessment.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
21.9 mg/L

Additional information

Immobilisation was assessed as part of a chronic toxicity test on Daphnia magna. No immobilisation of Daphids were observed at the highest tested concentration after 48h of exposure, hence the EC50 is greater than 21.9 mg/L mean measured concentration.

Two further studies are available, however provide limited or no information on the exposure levels, their analytical verification and effects observed, thus were disregarded from the assessment. Both studies report effect very low toxicity (EC50= 1188mg/L, EC50= 848 mg/L).
