Description of key information
Key data (lowest LC50 values) are:
-for Oncorrhynchus Mykiss: 0.169 mg Zn/l (single value) at neutral/high pH and low hardness
-for Pimephales promelas (single values) : 0.780 mg Zn/l at low pH (high hardness) and 0.330 mg Zn/l at neutral/high pH, high hardness
-for Pimephales promelas: LC50 0.780 mg Zn/l (at low pH); 0.33mg Zn/l at neutral/high pH
Key value for chemical safety assessment
Additional information
Good quality and relevant data for 5 species. Tests were done according to standard protocol or equivalent.
Data are grouped per species according to
-pH: low (6 -<7) - neutral/high (7 -8.5)
-and hardness: low/medium (<100mg CaCO3/l) and medium/high (>100 mg CaCO3/l).
Fish are generally less sensitive than invertebrates and algae.
