Results and discussion
Water solubilityopen allclose all
- Water solubility:
- < 0.003 µg/L
- Conc. based on:
- element
- Remarks:
- chromium ion
- Incubation duration:
- 7 d
- Temp.:
- 21.5 °C
- pH:
- 6
- Water solubility:
- ca. 0.005 µg/L
- Conc. based on:
- element
- Remarks:
- chromium ion
- Incubation duration:
- 28 d
- Temp.:
- 21.5 °C
- pH:
- 6
- Details on results:
- Withdrawn samples after both 7 and 28 days of exposure revealed concentrations of chromium below 0.02 µg/L. The chromium concentration (in 0.5 L test solution due to evaporation during the exposure period) can be approximated to less than 0.005 µg/L after 7 days and approximately 0.01 µg/L after 28 days ie. less than 0.025 µg/L after 7 days and approximately 0.005 µg/L after 28 days when normalised to a 1L solution (test volume without any solution evaporation). The results clearly shows that chromium containing metal particles release very low chromium concentrations.

Applicant's summary and conclusion
- Conclusions:
- Chromium containing compounds release very low concentrations; 0.005 µg/L after 7 days and approximately 0.01 µg/L after 28 days ie. less than 0.025 µg/L after 7 days and approximately 0.005 µg/L after 28 days when normalised to a 1L solution (test volume without any solution evaporation).
- Executive summary:
Withdrawn samples after both 7 and 28 days of exposure revealed concentrations of chromium below 0.02 µg/L. The chromium concentration (in 0.5 L test solution due to evaporation during the exposure period) can be approximated to less than 0.005 µg/L after 7 days and approximately 0.01 µg/L after 28 days ie. less than 0.025 µg/L after 7 days and approximately 0.005 µg/L after 28 days when normalised to a 1L solution (test volume without any solution evaporation). The results clearly shows that chromium containing metal particles release very low chromium concentrations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
