Abstract
Methods and systems for alleviating the environmental and health hazards associated with environmental contamination by metals are provided. Contained living or non-viable biomasses of metal-accumulating plant seedlings deplete the metal elements and compounds in metal-containing aqueous solutions. Concomitantly, the contained biomasses of plant seedlings accumulate the metal elements and compounds. The energy and nutrient stores of the seeds from which the seedlings develop are exploited to minimize the costs of remediating the metal-containing aqueous solutions.
