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

EC50/LC50 for freshwater invertebrates:
4 390 µg/L
EC50/LC50 for marine water invertebrates:
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.
