Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Test organisms

Test organisms (species):
Danio rerio (previous name: Brachydanio rerio)
Details on test organisms:
The body wet weight and body length of at least ten fish of the acclimated test fish batch will be determined prior to test start. The mean body length of the test fish will be about 2.0 ± 1.0 cm.

Study design

Test type:
static
Water media type:
other: Reconstituted test water consist of analytical grade salts dissolved in purified water to obtain these nominal concentrations: Ingredients Conc. (mmol/L) CaCl2 × 2H2O 1.0 MgSO4 × 7H2O 0.25 NaHCO3 0.38 KCl 0.038 Alkalinity 0.4
Limit test:
yes
Total exposure duration:
96 h

Test conditions

Hardness:
Water Hardness 1.25mmol/L 125 as CaCO3mg/L
Test temperature:
The water temperature in the test vessels will be maintained at 21–25 °C with a maximum deviation of ±1 °C during the test.
pH:
The pH of the test water after equilibration will be in the range of 7.0 to 8.5.
Dissolved oxygen:
oxygen saturation
Details on test conditions:
The test media will be aerated, if necessary to keep the oxygen concentration in the test medias sufficiently high (>60% of the air saturation).

A 16-hour light to 8 hour dark cycle will be used with a 30 minute transition period. Light intensity during the light period will be between 5 and 20 µE s-1 m-2.

The test duration will be 96 hours. The fish will not be fed during the test.
