Phytoremediation Of Contaminated Lands
About the Book
The present book contains the most relevant and up-to-date literature on phytoremediation technology with the aim to develop a basic and state-of-the-art volume on various theoretical and practical aspects in the realm of Phytoremediation. Most of the available books on the subject are edited volumes and present fragmented information. The present volume has the advantage of coherence of the subject matter which has been presented in an organized sequence. This compendium would serve a great purpose for all those students, teachers, scientists and research workers who are willing to deal with different problems of plant-soil relationships. As information on most of the techniques used in phytoremediation would be available at hand this would ease the job of workers in the field. This information would be of much importance to persons such as botanists, foresters, environmentalists, physiologists, nutritionists, agronomists as well as biogeochemists and persons particularly engaged in revegetation programmes.
The book begins by examining the problem, describing different type of wastes, their origin and production and various disposal systems, tailings, tailing dams and the effects of contaminants on biota, waste characteristics and the strategies available for remediation. Various subsets of phytoremediation technology such as Phytoextraction, Phytovoltalization, Phytostabilization, Phytodegradation, Rhizofiltration and Rhizodegradation have been discussed in detail. The text moves on to focus the latest information about elemental accumulation in plants, their uptake and translocation, role of phytochelators and phytosiderophores, the concept of accumulators and hyperaccumulators. Choice of plant species and methods of their establishment, considerations adopted in selection of plant species, the methods used and the most suitable agronomic practices to be adopted have been described. A chapter on conditioning alternatives describing various amendments such as FYM, poultry manure, sewage sludge, domestic refuse, saw dust, biogas slurry, fly ash, biochar, zeolite, bone meal, fertilizers, liming and the use of micro-organisms including Mycorrhizae, PSBs and Rhizobium has also been provided. A chapter deals with ways and means to enhance phytoextraction and its advantages and disadvantages. Attention has also been drawn towards advantages, limitations, prospects and economics of phytoremediation technology. Further, a chapter on biotechnological approaches to phytoremediation has been included. In the last, to trigger interest amongst teachers and students of higher-learning in the domain of phytoremediation, certain case studies which are based on the work carried out in author’s laboratory have been included. These would be illustrative for other such type of work to be carried out in India and abroad.

For the last 33 years or so, he is engaged in teaching environmental sciences and taxonomy of higher plants to the postgraduate and undergraduate students. His research interest included different areas in plant Sciences namely, Geobotany and Biogeochemistry of Mineral Deposits, Phytoremediation, Biomonitoring, Ecotoxicology and Biodiversity of higher plants. He is pioneer in India in the field of Geobotany and Biogeochemistry and has studied the mineral deposits of Pb, Zn, Cd, W and lately Uranium. Dr.Aery has visited different countries to attend conferences and training programmes, has published about 115 research papers in National and International journals of repute, has successfully completed 10 major research projects funded by various agencies and authored/edited 11 books. Twenty five students have completed their Ph.D and 04 are pursuing research work under his guidance. Presently, his group is pursuing studies on the environmental monitoring of naturally occurring radionuclides essentiality toxicity of Si, La, Ce, W and U in plants, phytoremediation of mining wastelands integrating Remote Sensing and GIS technology and relative agronomic evaluation of certain phosphatic fertilizers.
