Heavy metals always pose serious ecological risks when released into the environment due to their elemental non-degradable nature, regardless of their chemical form. This calls for the development of efficient and low-cost effluent treatment and metal recuperation technologies for contaminated waste water, not only because regulatory limits need to be met but also because the waste itself can be a resource for certain precious metals.

Biosorption is a general property of living and dead biomass to rapidly bind and abiotically concentrate inorganic or organic compounds from even very diluted aqueous solutions. As a specific term, biosorption is a method that utilizes materials of biological origin - biosorbents formulated from non-living biomass - for the removal of target substances from aqueous solutions. Recent research on biosorption provides a solid understanding of the mechanism underlying microbial biosorption of heavy metals and related elements.

This book gathers review articles analyzing current views on the mechanism and (bio)chemistry of biosorption, the performance of bacterial, fungal and algal biomass, and the practical aspects of biosorbent preparation and engineering. It also reviews the physico-chemical evaluations of biosorbents and modelling of the process as well as the importance of biosorption during heavy metal removal using living cells. It is a reference work for scientists, environmental safety engineers and R&D specialists who wish to further promote biosorption research and use the accumulated knowledge to develop and build industrial applications of biosorption in heavy metal separation technologies.

In recent years a boom can be seen in the literature dealing with phytoremediation. This Volume contains detailed explanation of the basic methods where plants are exploited in environmental remediation. The chapters represent an excellent description of the hottest topics in the field of phyto- and rhizoremediation.The first part of Volume 9 will supply the readers with up-to-date information concerning the necessary theoretical background, both concerning removal of heavy metals from the contaminated environment, and removal, detoxication and even degradation of toxic organic contaminants. Until recently phytoremediation has been discussed mostly in monographs dealing with microbiological remediation methods as a separate chapter, just to illustrate an additional possibility of use of biological systems.

Until recently phytoremediation has been discussed mostly in monographs dealing with microbiological remediation methods as a separate chapter, just to illustrate an additional possibility of use of biological systems. This book intends to show especially the importance of cooperation between plant and microorganisms, there is practically no phytoremediation without rhizoremediation. Newest approaches based on methods of molecular biology and genetic engineering are described, as well as plant science achievements. The great advantage of this volume is that the reader will find here in addition to a survey of published data also a lot of original findings, thus supplying an up-to-date review of this quickly developing field of science.
