Description of key information

Ethanol is practically non-toxic to aquatic invertebrates based on survival.  Based on reproductive parameters, it would be classified as slightly toxic.

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
9.6 mg/L

Additional information

In a very well reported invertebrate reproduction study, Daphnia magna were exposed to ethanol over a period of approximately 10 days, sufficient for the production of 3 broods of offspring. An LC50 of 454mg/l was reported for the adults but a much lower NOEC of 9.6mg/l was reported for the reproduction test, based on criteria of total progeny, number of broods and mean brood size.

 

Synopsis

EC50 (adult, mortality) = 454mg/l

NOEC (reproduction) = 9.6mg/l
