CAS number: 51-28-5
The majority of data have been obtained
from secondary source (EPA databank).
For 2,4 -dinitrophenol data for fresh and
marine ecosystems are available for all three trophic levels (alga,
crustacean and fish). Furthermore data on microorganisms and other
aquatic organisms are also available.
On the base on ecotoxicity data, 2,4
-dinitrophenol is very toxic to aquatic for algae and crustaceans, but
especially for fish.
In fact, the most conservative LC50 and
NOEC for freshwaterfish are 390 µg/L and 208 µg/L, respectively.
The most conservative data on algae and crustaceans are in any case low,
on the range of 1 -5 mg/L.
The same toxicity can be observed for
marine water, with an LC50 fish of 1500 µg/L , a NOEC fish of 940 µg/L
and a range of toxicity for algae and crustaceans of 5- 20 mg/L.
2,4-dinitrophenol is very toxic also for
biodegrader microrganisms. In an aerobic biodegradation and in a
biodegradation under methanogenic conditions with anaerobic digester
sludge studies the toxic level of c.a 10 -20 mg/L of 2,4-dinitrophenol
was defined, and a detailed study on sludge activity has setted a NOEC
(no inhibitory effect) at 4 ppm of 2,4-dinitrophenol.
2,4- dinitrophenol can be harmful for
other aquatic organisms as data on Aedes aegypti Yellow Fever Mosquito
Chironomids as Tanytarsus dissimilis Midge show (LC50 5-10 mg/L and LC50
of 48.1 mg/L, respectively). This latter organism, in its first larval
stage, lives also in sediment.
