An overview of the aquatic toxicity data can be found in the table below:

Test species and endpoint	Guideline	Exposure time	Result in mg/l	Remarks
Oncorhynchus mykiss - LC50	OECD TG 203	96h	5.7	In this semi-static test the results were based on time weighted mean average concentrations.Key study: Rel. 1
Daphnia magna - EC50	OECD TG 202	48h	3.8	In this static test the results are based on nominal concentrations because the measured concentration were very close to >=80% of the nominal values.Key study: Rel 1
Daphnia magna - NOEC	OECD TG 211	21 -days	>=0.891	In this semi-static test the immobilisation and reproduction results were based on time weighted average concentrations.Key study: Rel 1
Desmodesmus subspicatus - EC50 - ECr10 - NOEC	OECD TG 201	72h	>=14.4 - 1.9 - 0.78	In this static test the result were based on measured concentrations using geometric means.Key study: Rel 1
Activated sludge respiration - NOEC	OECD TG 209	3h	320	Nominal concentrations. Key study: Rel 1
