Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data have been obtained from secondary source (EPA databank), including several pubblication.
For short-term toxicity to crustaceans invertebrates many data for fresh and marine ecosystem are available.
EC50 for freshwater invertebrates of 4390 µg/L and LC50 20000 µg/L for marine water invertebrates have been choosen as the most relevant and conservative data.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 4 390 µg/L
Marine water invertebrates
Marine water invertebrates
- Effect concentration:
- 20 000 µg/L
Additional information
FRESH WATER
The most relevant and conservative study defines an EC50 of 4390 µg/l based on immobility. This value was measured by chemical analysis. 2,4 -dinitrophenol was tested on the crustacean Daphnia magna (Water Flea), in a flow-throught condition. The exposure duration was 48 hours while the application frequency once at day.
MARINE WATER
The most relevant and conservative study defines a mortality endpoint LC50 of 20000 µg/l. This value was measured by chemical analysis. 2,4 -dinitrophenol was tested on shrimp Palaemonetes sp. in an adult life stage, in a static condition in salt water. The exposure duration was 48 hours while the application frequency once at day. Temperature and salinity were measured during the test. Other effects as body burden were observed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
