Abstract: The toxicity of three heavy metals (copper, zinc and nickel) on an activated sludge biomass was studied by measuring several parameters of microbiological activity and the dynamics of microbial community composition. The effects on the microflora in the activated-sludge tank were evaluated by dosing the tank with different metal concentrations and a non-inhibiting concentration of copper for a 2-week period. The relationship between biological effects and chemical measurements was elucidated by principal compo…
