Description of key information
freshwater:
Data on 7 species available. Species NOECs range between 0.044 and 0.530 mg Zn/l (dissolved concentrations)
Marine:
Data on 1 species available. NOEC = 0.025 mg Zn/l (dissolved concentrations)
Species NOECs have been put into the respective species sensitivity distributions.
Key value for chemical safety assessment
Additional information
Extensive high quality chronic data were available on 7 (freshwater) and 1 (marine) fish species. These data were all screened for relevancy to the environment under study.
The freshwater species are part of 4 families: Cyprinodontidae (Jordanella), Cyprinidae (Phoxinus, Pimephales), Salmonidae (Oncorrhynchus, Salvelinus, Salmo trutta) and Cottidae (Cottus). The sensitivity of these species is equally distributed over the species sensitivity distribution. The fish species NOECs are combined with the other freshwater chronic data in the SSD to give the HC5 from which the PNEC is derived.
The saltwater species comes from the family Clupeidae (Clupea harengus). This species is not among the most sensitive ones in the species sensitivity distribution. The fish species NOEC is combined with the other marine chronic data in the SSD to give the HC5 from which the PNEC saltwater is derived.
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.
