EC number: 222-477-6
CAS number: 3486-35-9
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.
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
(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.
