Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

Sublethal observations / clinical signs:

Mortality at 96 hrs was 1, 0, 0, 6, and 7 in the 0, 3, 10, 30, and 100 mg/l treatments. Only four concentrations were tested which is less than a minimum of five concentrations stated in the guidelines. Water hardness was higher than targeted range of 50 - 250 mg/l as CaCO3. Hardness range of 264 - 288 mg/l as CaCO3 is normal for this laboratory and does not adversely affect the health of the fish. Analytical method used was gas chromatography-mass spectrometry. Mean reduction in the concentration of dissolved hydrocarbons during the test was 26% (range 9 - 42%).
