Metal Pollution and Forest Decline,p (Nriagu and Pacyna 1988). Among the elements which could affect plants, heavy metals are not naturally removed or degraded and therefore progressively accumulate in soil or water sediments (Bussotti et al. 1983; Hunter et al. 1987). In forest ecosystems different sources of heavy metal contaminati

Biogeochemical Processes in the Rhizosphere: Role in Phytoremediation of Metal-Polluted Soils,d part (topsoil, subsoil) of the soil profile. A multitude of remediation technologies has been developed for clean-up of heavy-metal-polluted soils (Iskandar and Adriano 1997; Pierzynski 1997). Classic methods, such as excavation, thermal treatment and chemical soil washing are typically expensive

Phytoremediation of Heavy Metal Contaminated and Polluted Soils, the soil matrix is adversely affected by the presence of deleterious substances or contaminants. These pollutants can be broadly classified into two groups: (1) organic, which contain carbon, and (2) inorganic, devoid of carbon (Webber and Singh 1995). The focus of this chapter is to provide an ove

Metal Removal From Sewage Sludge: Bioengineering and Biotechnological Applications,domestic wastewaters come from a number of sources: feces, pharmaceutical products, cosmetics, washing and cleaning chemicals, paints and other surface coatings etc. Since the source of these metals is non-point in nature, it is extremely difficult to practice source control. As a result, all these

Species-Selective Analysis for Metals and Metalloids in Plants,s had a number of different reasons reflecting the variety of areas in which plants are important, and the different roles played by the different elements. Indeed, whereas many elements (e.g. B, Se) are well established essential nutrients for the plant growth, others (e.g. Cd, Pb) are well-recogni

Experimental Characterization of Heavy Metal Tolerance in Plants, work has been dedicated to finding differences in plant metal tolerance and decipher the underlying physiological and genetic bases for these differences (reviewed by Antonovics et al. 1971; Ernst 1974; Woolhouse 1983; Baker 1987; Baker and Walker 1989, 1990; Schat and Ten Bookum 1992a; Macnair 199
