In the Klimisch 1 GLP study the acute toxicity of the test item on
Desmodesmus subspicatus was determined in an 48 hour static test
according to OECD 201 and EU method C.3. The test was performed with
concentrations of control and 0.01, 0.1, 1.00, 10.0 and 100 mg/L. The
measured concentrations of test item in the test media of the
biologically relevant test concentrations of 100 mg/L were between 101%
of the nominal values at the start of the test and 48% at the end of the
test. Thus, the correct dosage of the test item was confirmed. The test
item concentration declined in the test media over the test period of 72
hours. The biological results were related to the mean measured test
item concentrations calculated as the geometric means of the
concentrations measured at the start and end of the test. The data were
evaluated based on mean measured concentrations. The NOEC is 76 mg/L.
