the database of acute toxicity to freshwater invertebrates, there are
many high quality studies which predominantly report the 48h LC50as
the endpoint. Many species are represented in these studies, dominated byDaphnia
magnaandCeriodaphnia dubia. The 48h LC50s
values range from 0.013 mg Ni/L (Ceriodaphnia dubia;
Schubauer-Berigan et al., 1993) to 4970 mg Ni/L (Daphnia magna;
Chapman and Recht, 1980).
the database of acute toxicity to marine invertebrates, there are many
high quality studies which report predominantly 48h LC50 and
48h EC50 as the endpoint, representing many species. The 48h
LC50s values range from 0.23 mg/L (Haliotis refescens;
Hunt et al., 2002b) to 415 mg/L (Penaeus duorarum; Bentley
et al., 1975b). The 48h EC50 values range from 0.07 mg/L
(Diadema savignyi; Rosen et al., 2015) to 4.66 mg/L (Artemia
salina; Kissa et al., 2002b).
PNEC intermittent endpoint is not relevant for the identified processes,
no short-term tests are used in any PNEC derivation.
