Phytoremediation of Contaminated Soil and Groundwater

About this book

Phytoremediation is an exciting, new technology that utilizes metal-accumulating plants to clean soil contaminated with heavy metals and radionuclides. Phytoremediation is an attractive and economical alternative to current ex situ methods, which are expensive and unsafe. Read Phytoremediation of Contaminated Soil and Groundwater to learn just how far this burgeoning technology has developed.
