Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

6 aquatic invertebrate species were tested with quinoline, the relevant EC50 is 25 mg/L obtained in Daphnia magna.

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
25 mg/L

Additional information

The relevant EC50(48h) for daphnia has been chosen at 25 mg/L, while the validity of the study can not be checked due to lack of information. The other reported values are 34.5 mg/L and 51.3 mg/L. They are considered as similar.

A lower value was obtained in a 24h test: 14.7 mg/L, but this is not consistent with the other values. Another EC50 (24h) was found at 76 mg/L.

Other freshwater invertebrates (snails, crayfish, Gammarus and Chironomus larvae) were also tested but their susceptibility to quinoline seems to be either equivalent either lower than daphnia, except for Chironomus larvae, but the validity of these tests is not sufficient.
