Endpoint summary
Administrative data
Description of key information
No acute aquatic toxicity has been obversed in studies on oTDA-EO-PO in Fish, Daphnia and Algae.
A long-term study in Daphnia (using the structurally related substance oTDA-PO) indicates low chronic aquatic toxicity of the registration item.
Additional information
Fish
The acute toxicity of Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane to Fish (Danio rerio) was tested according to EU method C.1 'Acute toxicity for Fish' (2008). No toxic effects were observed during 96 hours exposure at a limit test concentration of 100 mg/L (Currenta, 2009).
Aquatic invertebrates
There are two studies available that determined the EC50 in aquatic invertebrates. Both studies assessed the acute toxicity of Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane according to OECD 202 and EU method C.2 ' acute toxicity for Daphnia' (2008). In both studies no toxic effects against D. magna was observed during 48 hours exposure at a limit test concentration of 100 mg/L (Currenta, 2009 and BASF, 2009). Thus, the EC50 of Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane is > 100 mg/L.
Long term toxicity to aquatic invertebrates is addressed via a read across approach. The 21 day-EC10 of the structurally related substance ortho-Toluenediamine, propoxylated in a OECD 211 guideline study is 2.5 mg/l (nominal) for reproduction.
(For details and justification of this read-across, please see information provided in the corresponding Endpoint Study record under 6.1.4)
Algae
The acute toxicity of Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane to Algae (Desmodesmus subspicatus) was tested according to EU method C.3 'Alga, Inhibition test' (2009). During 72 hours exposure an ErC50 of > 100 mg/L and EC10 of 63.4 mg/L was determined (Currenta, 2009).
Microorganisms / Sewage Treatment Plant (STP)
The potential toxic effect of Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane was tested according to EU method C.11, which is equal to OECD Guideline 209. Up to the highest nominal concentration of 1000 mg/L tested, Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane showed 2.0% respiration inhibition on activated sludge within 3 hours (Currenta, 2009).
