The successful implementation of phytoremediation depends on identifying plant material that is well adapted to specific toxic sites. Gentle remediation is then applied in situ, or at the contamination site. No soil excavation or transport is necessary. This severely contains the potential risk of the pollutants entering the food chain. And it's cost effective.
The progress of modern man has created many sites contaminated with heavy metals. The effected land is toxic to plants and animals , which creates considerable public interest in remediation. But the commonly used remedies are ex situ, which poses an expensive dilemma and an even greater threat. Phytoremediation offers the prospect of a cheaper and healthier way to deal with this problem. Read Phytoremediation of Contaminated Soil and Water to learn just how far this burgeoning technology has developed.
This is the first book to address the benefits of phytotechnologies from a design point of view, taking complex scientific terms and translating the research into an easy-to-understand reference book for those involved in creating planting solutions. Typically, phytotechnology planting techniques are currently employed post-site contamination to help clean up already contaminated soil by taking advantage of the positive effects that plants can have upon harmful toxins and chemicals. This book presents a new concept to create projective planting designs with preventative phytotechnology abilities, ‘phytobuffering’ where future pollution may be expected for particular site programs.
Filled with tables, photographs and detailed drawings, Kennen and Kirkwood's text guides the reader through the process of selecting plants for their aesthetic and environmental qualities, combined with their contaminant-removal benefits.
The book attempts to share real practical experience at all levels: local, regional, national and international, emphasising the co-operation between different professions and sectors that must take place to ensure adequate supplies of fresh water in future.
Understanding Wetlands explains how wetlands are created naturally and how they sustain themselves. It describes how the flora and fauna of these unique habitats are ideally adapted to their environment, and how the ecosystem copes with pollutants and climatic change. The impact of human activity such as farming, building, and recreation is also assessed. The book concludes with a look at the need for conservation and various conservation techniques.
This integrated and holistic account of wetlands is a valuable reference for students of ecology, biology, and environmental science. Its beautiful illustrations and accessible style also make it ideal for the general reader with an interest in the natural world.
