Description of key information

Data have been obtained from secondary source (EPA databank), including several pubblication.

For long-term toxicity to invertebrates only data for fresh water are available.

NOEC for freshwater crustaceans of 2000 µg/L has been choosen as the most relevant and conservative data.

Key value for chemical safety assessment

Fresh water invertebrates

Effect concentration:
2 000 µg/L

Additional information


The most relevant and conservative study defines a mortality endpoint NOEC of 2000 µg/l, based on reproduction effects. This value was not measured by chemical analysis. 2,4 -dinitrophenol with a purity of was tested on Daphnia magna (Water Flea) in a renewal condition. The exposure duration was 21 days. Two replicates were done. Temperature, pH and dissolved oxigen were measured during the test. Furthermore, mortality was observed.
