Despite its advantages, phytoremediation has some limitations:
Slow Process: It can take several growing seasons to achieve significant contaminant reduction. Depth Limitation: Effectiveness is generally limited to the root zone, making it less effective for deep soil or groundwater contamination. Contaminant Specificity: Not all plants can remediate all types of contaminants, and some contaminants may be toxic to the plants themselves. Weather Dependency: Plant growth and effectiveness can be influenced by climatic conditions.
