For the higher plants, the acute EC50 values for Lemna
minor varied between 221.7 µg dissolved Pb/L (at pH 7.9) and 1674 µg
dissolved Pb/L (at pH 7.2)
Six different chronic non-normalised no-effect levels for
freshwater higher plants situated between 85 µg dissolved Pb/L (Lemna
minor; endpoint: root growth rate) and 1025 µg dissolved Pb/L (Lemna
minor; endpoint: root growth rate) were extracted. One no-effect
level for marine higher plants of 11.9 µg dissolved Pb/L (Champia
parvula; endpoint: reproduction) was found.
