Description of key information
Key value for chemical safety assessment
Additional information
For ZnS, the long term aquatic toxicity tests on aquatic invertebrate is waived (because no exposure to zinc ions is anticipated).
Copper content in GSS is highly low (about 100 ppm), and bonded to the structure of ZnS (Zn is partially substituted with Cu), and according to the water solubility test, there is no copper detected(less than 0.0251 mg/L at PH 8.9). So the effect of copper iron can also be ignored.
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.
