The long-term toxicity to fish was waived as acute testing with CdTe on fish did not show toxicity at 1g CdTe/L.
However, as Cd2+ ion determines ecotoxicity the PNEC deriviation will be based on the Cd2+ ion as determined in the RA (ECB 2007).
The long-term toxicity to fish was waived as acute testing with CdTe on
fish did not show toxicity at 1g CdTe/l, while some toxicity was
observed in acute tests with algae and invertebrates. This observation,
combined with the knowledge that invertebrates are the most sensitive
taxonomic group for the Cd ion, as follows from the extensive database
on chronic toxicity of soluble Cd compounds (invertebrates mean toxicity
3.04µg Cd/l (22 species NOECs, lowest value 0.21µg/l; fish mean toxicity
10.8µg Cd/l (18 species NOECs, lowest value 0.47µg/l; algae mean
toxicity 9.13µg Cd/l (8 species NOECs, lowest value 0.85µg/l) justifies
to waive the chronic fish test.
