Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Any other information on results incl. tables

Cadmium concentration in solution after 7 days at 1mg/l loading was 2.71 µg/l, coefficient of variation: 15%

Cadmium concentration in solution after 28 days at 1mg/l loading was 5.75 µg/l, coefficient of variation: 12%

Applicant's summary and conclusion

Tests of good quality and considered useful for assessing the effect on the endpoint
Executive summary:

Cadmium sulfide powder was introduced at 1 mg/L in a CO2-buffered aqueous medium at pH 6 (used as worst case for all pH values).

Transformation/dissolution was accomplished by standardised agitation, sampling and analysing

of the solutions at specific time intervals. The short-term (acute) transformation/dissolution was 2.71 (15% CV)

after a 7 days transformation/dissolution period. The long-term (chronic) transformation/dissolution was 5.75 µg Cd/l (CV:1after a 28 days transformation/dissolution period.%).
