EC number: 255-449-7
CAS number: 41583-09-9
The substance is acutely not harmful to freshwater invertebrates.
As the substance is a salt of phosphate, effects can be read-across from
the cation, which is likely to have the more important effects. Inbiological
systems, phosphate is an abundant in cells and body fluids. In
ecological terms, because of its important role in biological systems,
phosphate is a highly sought-after resource. Thus, read-across from
component CAS Reg.-No. 108-78-1, melamine, is justified. All effect
values are minimum values as the molar ratio anion:cation equals 1.74.
The results of the studies are summarized in the table below. Both
mortality as regulatorily relevant values as well as mobility/behavior
as additional endpoints were assessed. Effects on mortality revealed
LC50 values > 1000 mg/L. However, slight effects on mobility/behavior
could be detected at lower concentrations. Here, the EC50 values were at
200 mg/L and < 180 mg/L, respecitively. The substance is acutely not
harmful to aquatic invertebrates.
LC50 > 1000 mg/L (mortality) / EC50 = 200 mg/L (mobility/behavior)
conducted with CAS 37640 -57 -6
LC50 > 2000 mg/L (mortality) / EC50 < 180 mg/L (mobility/behavior)
