Acute aquatic toxicity test results are used
in the risk assessment since chronic data were not available. Aquatic
toxicity against aquatic invertebrates, fish and aquatic plants is
addressed by experimental results. The lowest short-term toxicity value
is the ErC50in Daphnia magna of 0.0955 mg/L. In an
activated sludge respiration inhibition study an NOEC of 0.025 mg/L was
determined. Therefore, the substance is considered to elicit adverse
effects against aquatic/STP organisms that would identify a relevant
hazard and justifies PNEC derivation for regulatory purposes.
In acute aquatic toxicity tests, the test
item revealed LC50/EC50values below 1 mg/L, and
thus needs to be classified as hazardous to the aquatic environment in
accordance with Section 22.214.171.124., Annex I of Regulation 1272/2008/EC. As
the test item is not considered readily biodegradable, the relevant
classification is Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410).
