Additional information
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:
Fish:
The acute toxicity of the test substance on Oncorhynchus mykiss was investigated in a GLP guideline study according to OECD 203. In this limit test, no toxic effects on the test organisms were observable at an analytically verified concentration of 120 mg/L [BASF SE, 2012]. Hence, the test substance is not considered to be acutely harmful to fish.
Aquatic invertebrates:
The acute toxicity of the test substance on Daphnia magna was investigated in a GLP guideline study according to OECD 202. In this limit test, no toxic effects on the test organisms were observable at an analytically verified concentration of 120 mg/L [BASF SE, 2012]. Hence, the test substance is not considered to be acutely harmful to aquatic invertebrates.
Algae:
The toxicity of the test substance to green algae was investigated in a GLP guideline study according to OECD 201 [BASF SE, 2012]. In this study, the EC10 as well as the EC50 value of the test substance on the growth rate of Pseudokirchnerella subcapitata was determined to exceed the highest nominal test concentration of 400 mg/L (analytically verified value). Hence, the test substance is not considered to be harmful to aquatic algae.
Microorganisms:
In a GLP guideline study according to OECD 209 an EC10 (3h) of 180 mg/L was determined [BASF SE, 2012]. Hence, the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
