Phytoremediation can help clean up contaminated soil by using plants like Indian mustard to absorb lead and other metals. Scientists found that adding synthetic chelating agents to the soil can help plants accumulate more lead in their tissues. By using chelates like EDTA, the plants were able to take up higher levels of lead from the soil, showing that this method can enhance metal uptake in plants. This research demonstrates that using synthetic chelates can boost the ability of Indian mustard to accumulate lead and other metals from contaminated soil, making phytoremediation more effective.
