"This title discusses various effects of heavy metal exposure to legumes as well as the bioremediation potential of rhizosphere microbes. Availability of heavy metals, their uptake and the effects of metals on various signaling pathways within legumes are presented. Furthermore, the effects of heavy metals to nitrogen fixing microorganisms and how microsymbionts can overcome metal stress is presented in detail. The role of nitrogen fixers in decontamination of heavy metal toxicity, mycoremediation of metal contaminated soils, microbially mediated transformation of heavy metals and action of plant growth promoting rhizobacteria and nitrogen fixers together in detoxifying heavy metals are broadly explained."

"This title focuses on the many aspects of the interaction between plants and heavy metals. Not only it describes the effects of heavy metal toxicity on the plant cell and its organs but it also examines the mechanisms that plants adopt to scavenge heavy metals at cellular, physiological, and metabolic level. Plants and Heavy Metals also analyses Hyperaccumulator plants and shows their potential role in phytoremediation technologies in light of the recent research results."

"A survey on heavy metal content in seawater and sediment was conducted in Jakarta bay in May and October 2004.There is indication of significant presence of heavy metal in sediment...."

"Five sediment cores from the fresh water region of the vembanad wetland system were studied for the trace element contents the average concentration of iron ,manganese, nickel, copper, zinc,cadmium,lead, mercury and chromium were determined...."

"Heavy metals in suspended sediments (SS) were investigated in the lower Chao Phraya River,Thailand, and Main particulate metals. The particulate fractions accounted mostly for 60-100% of total concentrations of Cr, Mn, Ni, Cu, Zn, and Pb in both dry and rainy seasons. The comparison of metal contents of the sampled SS and upper continental crust (UCC) implied some anthropogenic inputs of Cr, Ni,Cu, and Zn as well as the dilution process for those metals in the rainy season in Chao Phraya River. Enrichment factor in both rivers also indicated anthropogenic effects on metal content in SS,reflecting the distinctive seasonal process in Chao Phraya River and the spatial variation withinMaxil."

"The abality of light expanded clay aggregate to remove lead and cadmium from paint industry's effluents was studied at different levels of adsorbent, contact time and pH in April 2008...."
