Brunetti et al. (2011) claimed that the heavy metal accumulation capacity of corn grown in contaminated sites varies considerably from that of corn grown in greenhouse pots. In this study, an in situ plant test was conducted to study corn׳s uptake of heavy metals. In the Niuyunjue region of Nantou City, Taiwan, the soil has a silt loam texture, which is suitable for producing ceramic products. During the past 200 years, people in this area have used local soil materials to manufacture ceramics. Ceramic glazing waste, compounded by improper disposal of waste and wastewater, has resulted in lead contamination in many areas of agricultural land. The remediation costs of physical–chemical treatment techniques (e.g., acid extraction, electrokinetics, overturn dilution) are counterproductive to reducing the lead contamination to less than 150 mg/kg. Thus, this study evaluated the economic benefits and heavy metal attenuation effects of planting corn on-site to identify an alternative sustainable use of contaminated soil.
