Ash dykes, lagoons, and ash ponds are often used for disposing of coal combustion residue but raise significant environmental concerns due to the leaching of heavy metals into nearby ecosystems. Phytoremediation harnesses the natural abilities of certain plants to absorb, accumulate, or detoxify these heavy metals from soil and water, presenting a sustainable and cost-effective approach to remediation. The effectiveness of phytoremediation in ash dykes is influenced by factors such as the choice of plant species, soil characteristics, and contaminant levels. This pot modeling study aimed to investigate how different plant species affect heavy metal remediation through phytoremediation. By assessing the effectiveness of various species, the study sought to identify the most suitable options for remediation. A plant growth chamber equipped with sensors was used to monitor plant physiological responses, enabling data-driven decisions to enhance remediation efficiency. This approach aims to provide a long-term sustainable solution for addressing contamination in ash dyke sites.
