Details on test organisms:
TEST ORGANISM
- Common name: water flea
- Source: The clone of Daphnia magna STRAUS 1820
used was supplied by the Institut National de Recherche Chimique Appliquée, France, in 1978. From this date on this clone was cultured and bred continuously in the Laboratory of Ecotoxicology of the Experimental Toxicology and Ecology of BASF SE in Ludwigshafen.
- Age at study initiation (mean and range, SD): < 24 hours (at least 3rd brood progeny)

Study design

Test type:
static
Water media type:
freshwater
Limit test:
no
Total exposure duration:
48 h

Results and discussion

Effect concentrations
Duration:
48 h
Dose descriptor:
EC50
Effect conc.:
4.59 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat.
Basis for effect:
mobility
Remarks on result:
other: Nominal concentrations verified analytically

Any other information on results incl. tables

Since the analytically determined concentrations of the test substance in the test solutions were within +20% of the nominal concentrations, the effect concentration can be expressed relative to the nominal concentration.
