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.
