With high probability acutely not harmful to aquatic organisms. The
inhibition of the degradation activity of activated sludge is not
anticipated when introduced in appropriate low concentrations.
This aquatic toxicity assessment was based on the following data:
The acute toxicity of the test substance on zebra fish was measured in a
GLP guideline study according to OECD 203. The LC50 value was determined
to be greater than 450 mg/L (BASF SE 17/F0200/965034, 1998).
Additionally, a read-across study on zebra fish is available. The LC50
value on the animals was found to be greater than 100 mg/L (BASF AG
17F0283/ 965066, 1997). Based on these data, the test substance is
considered with as high probability acutely not harmful to fish.
The acute toxicity of the test substance on daphnids was measured in a
GLP guideline study according to OECD 202. The EC0 value was determined
to be greater than 100 mg/L (BASF AG 96/0251/50/1, 1996). Additionally,
a read-across study on daphnids is available. The EC50 value on the
animals was also found to be greater than 100 mg/L in this study (BASF
AG 9610339/5011, 1997). Based on these data, the test substance is
considered with as high probability acutely not harmful to aquatic
In a GLP guideline study according to OECD 201 the EC50 value on the
growth rate of green algae was determined to be 313 mg/L (Rohm and Haas
06RC-262, 2007). The NOEC was observed to be 50 mg/L. Therefore the
tested substance is considered as acutely not harmful to algae.
