Contamination, aquatic environment, mercury, microalgae


Despite the existence of physicochemical decontamination methods, these have proved to be ineffective and costly, so biological treatments such as phytoremediation are currently gaining ground as they are low-cost and environmentally friendly. The aim of this work was to evaluate in vitro the growth capacity of the microalga Chlorella vulgaris for 25 days in the presence of Hg2+ and subsequently subjected to concentrations of 1.0, 2.0 and 3.0 mg/L of HgCl2. The results show the efficiency of the microalgal Chlorella vulgaris to grow with different behaviours in the three concentrations of mercury in the form of HgCl2. The data obtained indicate the ability of this microalga to remediate mercury in aquatic environments contaminated with this metal.
