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.

Additional information

The lowest valid acute test results of aquatic testing determined for fish, daphnia, algae and bacteria were as follows:


Cyprinodon variegatus: 96h-LC50 = 140 mg/l (freshwater)

Pimephales promelas: 96h-EC50 = 228 mg/l (marine water)

Daphnia magna: 48h-EC50 = 120 mg/l

Scenedesmus subspicatus: 72h-EbC50 = 475 mg/l;

                                        72h-EbC10 = 64 mg/l

Activated sludge: 3h-EC50 = 100 mg/l


In 3 fish early-life-stage tests with Pimephales promelas NOEC-values of 4.2 mg/l (32 d), 15.6 mg/l (32 d) and 11 mg/l (35 d) were obtained for the endpoint growth (measured as weight). The geometric mean of these 3 NOEC values is 8.9 mg/l.
