【発明の名称】金属蓄積性植物を用いて汚染媒体から鉛及び有機鉛を得る方法
Document Type and Number:
Japanese Patent JPH07508206
Kind Code:
A
Abstract:
It has been found that Ambrosia sp. and Apocynum sp. accumulate lead in the leaves, stems, and roots when it grows in soil containing organic or inorganic species of lead. Lead is accumulated in the leaves and stems to a greater extent than in most other plants. Lead can be economically recovered from contaminated soil and sludge by harvesting Ambrosia sp. or Apocynum sp. grown in media containing high concentrations of lead.
