Oncorhynchus mykiss

OECD 203

96h-LC50

2.2 mg/l

Concentrations declined with 20-30% during 24h semi-static exposure. Therefore measured concentrations were used for determining LC50.

Key study, GLP, rel. 1

Daphnia magna

OECD 202

48h-EC50

1.6 mg/l

Measured concentrations were used but analytical concentration remained within 80-100% of the nominal concentrations.

Key study, GLP, rel. 1

Selenastrum capricornutum, Strain No. CCAP 278/4.

OECD 201

72h-ErC50

NOEC

2.58 mg/l

0.26 mg/l

Concentrations declined with 40-50% during 72 hours exposure. Therefore measured concentrations were used for ECr50 and NOEC values

Key study, GLP, rel. 1

Activated sludge

OECD 209

3 hours EC10

>=100 mg/l

Nominal values

Key study, GLP, rel. 1
