Resumen:
The aim of this research was to study the nutrient influence on the tolerance, the removal efficiency and the metal accumulation of T. domingensis exposed to high concentrations of metals added together. We hypothesized that nutrient enrichment enhances the metal tolerance of this macrophyte, favouring its metal uptake efficiency. Nutrient addition did not affect metal removal from water significantly.Despite the fact that plants showed growth inhibition, nutrient addition favoured tolerance and metal accumulation in tissues.Plant tissues accumulated the three metals efficiently. However, the sediment was the compartment that showed the highest metal accumulation due to its significantly higher mass considering plant biomass.These results could be applied to enhance metal removal efficiency of constructed wetlands where nutrient enrichment could be attained by treating sewage together with the industrial effluents.
