For algae, 7 individual reliable freshwater acute toxicity data points for one species were put forward for hazard assessment purposes. The acute toxicity values (48h-LC50) for Pseudokirchneriella subcapitata varied between of 21.7 µg dissolved Pb/L (at pH 7.5 and hardness of 24.2 mg/L) and 322.9 µg dissolved Pb/L (at pH 7.3 and hardness of 174.4 mg/L). 2 different chronic high quality no-effect levels for dissolved lead for freshwater algae situated between 34.1µg Pb/L and 93.0 µg Pb/L (Pseudokirchneriella subcapitata) were observed. High quality no-effect levels for dissolved lead for marine algae plants were situated between 52.9 µg Pb/L (Skeletonema costatum; endpoint: yield) and 1231.8 µg Pb/L (Dunaliella tertiolecta; endpoint: growth rate).
