2. Materials and methods
In situ corn growing tests were performed in plots of lead-contaminated and uncontaminated agricultural land in the Niuyunjue region of Nantou City, Taiwan. The height, biomass yield, lead content of various plant parts, and combustion heat of the corn plants was measured. Moreover, the study team assessed the impact of lead-contaminated soil on the corn growth, evaluated the economic income obtained from using corn products for animal feed or bioenergy, calculated the removal efficiency of lead, and determined the feasibility of using corn in phytoattenuation for simultaneous production and remediation.
