Trilead dioxide phosphonate

Short-term toxicity to fish

Description of key information

For fish, 51 individual reliable acute toxicity data points for three different species were put forward for hazard assessment purposes. The acute toxicity values (96h-LC₅₀) for Pimephales promelasvaried between of 40.8 µg dissolved Pb/L (at pH 5.67 and hardness of 15.9 mg/L as CaCO₃) and 3597.9 µg dissolved Pb/L (at pH 7.1 and hardness of 26 mg/L as CaCO₃). The acute toxicity values (96h-LC₅₀) forOncorhynchus mykiss varied between of 127 µg dissolved Pb/L (at pH 7.6 and hardness of 32 mg/L as CaCO₃) and 1470.0 µg dissolved Pb/L (at pH 8.8 and hardness of 290 mg/L as CaCO₃). For the fishPoecilia reticulataa LC₅₀value of 1990 µg dissolved Pb/L was retreived.
