Abstract
A nanobioremediation method is for soil in a high-concentration polycyclic aromatic hydrocarbon (PAH)-contaminated site. The method includes adding a carbon nanomaterial and a base fertilizer to soil in a high-concentration PAH-contaminated site, evenly broadcast sowing alfalfa seeds to the contaminated soil, and keeping the soil moisture content at 60% of the field moisture capacity, and when the alfalfa grows to the flowering or maturity stage, harvesting and removing the plants from the contaminated soil.
