(a)
Type of test: static [ ]; semi-static [ X ]; flow-through [ ]; other (e.g. field test) [ ]
open-system [ X ]; closed-system [ ]
Species: Medaka (Oryzias latipes)
Exposure period: 96 h
Results: LC50 (24h) = 5.1 mg/l
LC50 (48h) = 5.1 mg/l
LC50 (72h) = 5.1 mg/l
LC50 (96h) = 5.1 mg/l
Analytical monitoring: Yes [ ] No [ X ] ? [ ]
Method: OECD TG 203 (1992)
GLP: Yes [ ] No [ X ] ? [ ]
Test substance: As prescribed by 1.1 - 1.4, purity: 99.5%
Remarks: Group of ten Medaka were exposed to nominal concentrations of 2.0, 3.0,
4.5, 6.8 and 10 mg/l. 100 mg/l DMSO & HCO-40 (4:1 weight ratio,) was
used as solubilizer. 100 mg/l solubilizer and dechlorinated tap water were
used as control. The LC50 (96h) was determined to be 5.1 mg/l with 95 %
confidence limits of 4.7 mg/l to 5.8 mg/l.
