Short-term toxicity data were extracted from literature for bacteria
(heterotrophs and nitrifiers) and different protozoan species. 2
different no-effect levels for lead, between 1.06 and 2.92 mg/L
(depending on the exposure time), were compiled for heterotrophic
bacteria. For nitrifiers, 2 different no-effect concentrations, between
2.79 and 9.59 mg/L, were observed. 14 different short-term toxicity data
were selected for protozoan species/communities. No-effect
concentrations for protozoan communities varied between 1.0 and 7.0 mg
Pb/L, while LC50 values for protozoan varied between <1.5 and >250.0
