Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Data on 7 species available. Species NOECs range between 0.044 and 0.530 mg Zn/l (dissolved concentrations)
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.
