Description of key information

For fish, 47 individual reliable acute toxicity data points for two different species were put forward for hazard assessment purposes. The acute toxicity values (96h-LC50) for Pimephales promelas varied between of 40.8 µg dissolved Pb/L (at pH 5.67 and hardness of 15.9 mg/L) and 3597.9 µg dissolved Pb/L (at pH 7.1 and hardness of 26 mg/L).The acute toxicity values (96h-LC50) for Oncorhynchus mykiss varied between of 107.0 µg dissolved Pb/L (at pH 8.8 and hardness of 290 mg/L) and 1170.0 µg dissolved Pb/L (at pH 6.9 and hardness of 32 mg/L).
