Phytoremediation is a new environmental pollution control technology that uses some plants that can tolerate and super-enrich toxic elements and their coexisting microbial systems to remove pollution. Phytoremediation system can be regarded as a water pump powered by solar energy and a plant reactor for biological treatment. Plants can absorb and transfer elements and compounds, accumulate, metabolize and fix pollutants. It is an important way to fundamentally solve soil pollution.
Which of the following statements does not belong to the advantage of phytoremediation?
Less disturbance to the environment, no need for excavation, transportation and huge disposal sites
