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.

Description of key information

The acute toxicity of the substance to fish (Danio rerio) was tested in a static test. After 96 hours of exposure, a LC0 of ≥100 mg/L was determined. A LC50 of >100 mg/L was calculated (Weyers, 2005).

"should read: > 100mg/l"

The acute toxicity of the substance to fish (Danio rerio) was conducted in accordance with Council Regulation (EC) No 440/2008, Method C.1 'Acute toxicity for Fish' (2008) which is in most parts equivalent to the OECD Guideline for Testing of Chemicals No. 203 'Fish, Acute Toxicity Test' (1992).

A group of ten fish of the recommended size was exposed to a limit test concentration of nominally 100 mg/L of the substance dissolved in dilution water. Observations were made on the number of dead fish and the incidence of sub-lethal effects after 2, 24, 48, 72 and 96 hours of exposure. No toxic effects against fish were observed at a limit test concentration of 100 mg/L under exposure conditions. The results are expressed in terms of nominal concentrations since no analytical monitoring was carried out

This toxicity study is classified as acceptable and satisfies the guideline requirements for the acute Fish study.
