Description of key information
For assessing the aquatic hazard of CdZnS, reference has been made to ecotoxicity data obtained by standard testing on CdTe, a sparingly soluble Cd-compound. Transformation dissolution data demonstrate that the solubility of Cd in CdZnS is even much lower than the solubility of Cd from CdTe (>16-50 times lower solubility of Cd in CdZnS, as compared to solubility in CdTe). The ecotoxicity of CdTe was therefore used as a worst case for the ecotoxicity of CdZnS.
Three plant ecotoxicity studies were performed with CdTe. No acute effects were seen up to a concentration of 2.1 g CdTe/kg DW or 1 g Cd/kg DW.
As Cd2+ ion determines ecotoxicity, the PNEC deriviation for the terrestrial compartement will be based on the Cd 2+ ion as determined in the RA (2008).
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 2 100 mg/kg soil dw
Additional information
Three limit tests according to the OECD protocol no 208 were performed using Phaseolus vulgaris, Lepidium sativum and Secale cereale as test species. A control and a concentration of 2.1 g CdTe/kg DW or 1 g Cd/kg DW were tested. No effects were seen at this concentration for the three plant species.
