Description

Plants use their natural ability of mineral absorption to remove toxic metals from the contaminated environment. This book describes hyperaccumulation of chromium, from tannery effluent by using an aquatic macrophyte Spirodela polyrrhiza (L.) Schleid. and its effect on growth and photosynthetic pigments of the test plant. The literature review highlights various studies carried out on heavy metal accumulation in plants and their impact on the hyperaccumulating plant. Other than hyperaccumulation and toxicity studies, attempt has also been made to study the translocation of chromium in Spirodela and various mechanisms operating during such translocation. This book is an essential reading for environmentalists and physiologists who have an interest in plant bioaccumulators, and industrialists interested in adopting economically and environmentally sustainable contaminant remediation technologies. It will also be of great interest to students of environmental science specializing in phytoremediation.
