A METHOD FOR DETERMINATION OF PHYTOREMEDIATION CAPABILITY OF RICE (ORYZA SATIVA L.) AND WEED SPECIES FOR HEAVY METALS IN CONTAMINATED AGROECOSYSTEM SOIL IN A TROPICAL COUNTRY

摘要

A process for removal of metal ions from soil and methods for effecting such removal are described. The process is based on the growth of crop and crop-related members of the plant family Brassicaceae in metal-containing soils. These particular plants will absorb metals into their roots making them not leachable from the soils or will absorb the metal into their roots and transfer them to the shoots which can be easily harvested.
