Description of key information
The substance was found to dissipate rapidly from the test media in the conducted aquatic toxicity tests, despite the use of semi-static test systems for most studies. Nevertheless, the substance had adverse effects on aquatic freshwater organisms on all three trophic levels tested.
The acute aquatic toxicity studies produced the following results:
96-hour LC50 = 0.69 mg/L in fish
48-hour EC50 = 1.54 mg/L in invertebrates
72-hour ErC50 >0.081 mg/L in algae
Furthermore, the long-term aquatic toxicity studies gave the following results:
22-day NOEC = 0.044 mg/L in fish
9-day NOEC = 0.284 mg/L in fish
21-day NOEC = 0.0185 mg/L in invertebrates
72-hour ErC10 = 0.0439 mg/L in algae
The substance had also some effects on the activity of microorganisms in activated sludge, and the 3-hour NOEC for respiration inhibition was 100 mg/L, whereas the EC50 value was >1000 mg/L.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
