Water pollution from port activities generates various impacts on the environment and human health. In the Peruvian jungle, the Ucayali River is one of the water bodies that has an important ecosystemic value for the city of Pucallpa; however, the latest monitoring conducted by the National Water Authority (ANA) has shown that the concentration of lead in the water exceeds the maximum admissible values according to the Environmental Quality Standards (ECA), generating a degradation in the quality of its waters. Therefore, the present study proposes the application of Eichhornia crassipes (water hyacinth) to remove lead concentration in contaminated water on a bioassay scale. Three treatments were performed using distilled water and lead nitrate to prepare solutions with three different concentrations (T1: 0.0014 mg/L, T2: 0.0022 mg/L, T3: 0.0033 mg/L) which were obtained after averaging the results of ANA effluent monitoring between 2014 to 2021 in 5 monitoring points of this entity. The results showed the capacity of the species to remove lead, obtaining the highest efficiency in the treatment with the highest concentration (T3=25.1%); however, the morphological parameters of the plant were affected by a reduction in root size, yellowing of the leaves (chlorosis) and a reduction in biomass weight. The study also evaluated the effects on physicochemical parameters in the water following treatments with the species.
