Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Growth of the green alga Selenastrum capricornutum (new name: Pseudokirchneriella subcapitata) tested according to EPA OPP 122-2 (Algal Toxicity, Tiers I and II), was inhibited during the 5 d incubation period with an EC50 value of 4.9 µg/L and a NOEC of 1.83 µg/L.

No other aquatic toxicity was observed at concentrations up to the solubility of the substance. The following data were measured:

For blue-green algae (tested: Anabaena flos-aquae) no inhibition of algal growth was observable up to the maximum technically achievable concentration of the substance at approximately 0.058 mg/L.

Acute toxicity to fish: LC50 (Danio rerio, 96 h, EEC Methods for Determination of Ecotoxicity Annex to Directive 92/69/EEC (O.J. No. L383A, 29.12.92) Part C, Method 1 Acute toxicity to Fish) LC50 (fish) > 1 mg/L

Chronic toxicity to fish ((Cyprinodon variegatus variegatus, early-life stage: reproduction, (sub)lethal effects): LC50 (fish) > 0.78 - < 1.9 mg/L

Acute toxicity to invertebrates (Daphnia magna, 48 h, OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)) EC50 > limit of solubility (> 0.003 mg/L = highest concentration achievable)
