This work has examined sewage sludge of the following heavy metal concentrations (mg/kg): Cd-3.43; Co-5.25; Cu-131; Fe-51300; Mn-177; Ni-37.5; Pb-104; Zn-3300. Metals speciation by sequential extraction according to Tessier et al. (1979), and Rudd et al. (1988), and a procedure recommended by European Community Bureau of Reference (BCR) (Ure et al., 1993; Quevauiller et al., 1996; Davidson et al., 1999), as well as analysis of chemical forms of metals, have been carried out. It has been found… Expand
Chemical and Biological Leaching Methods to Remove Heavy Metals from Sewage Sludge: A Review
The removal of heavy metals (HMs) in sewage sludge (SS) is important since sludge is often disposed or applied on farmland to enhance soil fertility. The present study reviewed two conceptualExpand
Progressive Acidification: An Aspect of Chemical Leaching of Sewage Sludge
The effect of progressive acidification using inorganic and organic acids in chemical leaching of sewage sludge was studied. Results of analyses using Atomic Absorption Spectrophotometer (AAS) showedExpand
Effect of Drying Process on Heavy Metals Fractionation of Contaminated Sludge for Land Application
Metal fractionation studies on metals in sludge are usually done on dried sludge. Although there are advantages in this form of sludge, it is possible that fractionation of metals in sludge may beExpand
Analytical Capabilities of the Community Bureau of Reference Protocol to Estimate the Mobility of Nutrients and Toxic Elements from Mineral Fertilizer.
X-ray diffraction, scanning electron microscopy, and energy dispersive spectroscopy analyses of solid residues showed that the ways in which elements were distributed in the sample particles could affect their mobility. Expand
Potato absorption and phytoavailability of Cd, Ni, Cu, Zn and Pb in sierozem soils amended with municipal sludge compost
Effects of sludge utilization on the mobility and phytoavailability of heavy metals in soil-plant systems have attracted broad attention in recent years. In this study, we analyzed the effects ofExpand
Comparative metal (Cu, Ni, Zn, total Cr, and Fe) removal from galvanic sludge by molasses hydrolysate
BACKGROUND The objective of this study was to evaluate the chemical extraction efficiency of five metals (Cu, Ni, Zn, total Cr, and Fe) from galvanic sludge using molasses hydrolysate producedExpand
A critical review of ferrate(VI)‐based remediation of soil and groundwater
Diverse synthesis recipes for ferrates (FeVIO42‐) and their associated physicochemical properties as oxidants, coagulants, and disinfectants for the elimination of a diverse range of chemical and biological species from water/wastewater samples are reviewed. Expand

Metal content variation in wastewater and biosludge from Bangkok's central wastewater treatment plants
Abstract The objectives of this study were to determine the metal contents and their variations in influent, effluent and biosludge, and to evaluate the potential environmental impact of biosludgeExpand
A comparison of the application of different waste products to a lettuce crop: Effects on plant and soil properties
A romaine-type lettuce (Lactuca sativa L.) was cultivated during three successive crop seasons in an agricultural land near the Wastewater Treatment Plant (WWTP) of Alcazar de San Juan. FourExpand


The Occurrence of Metals in Composted Municipal Wastes and Their Removal
The organic fraction of municipal wastes has been composted on the laboratory scale. In the obtained compost the content of cadmium, cobalt, copper, manganese, nickel, lead and zinc were determined,Expand
Characterisation of metal forms in sewage sludge by chemical extraction and progressive acidification
Sequential chemical extraction, acidification to pH 4, 2 and 0.5, and repetitive CaCl2 (0.05 M) extractions were used to evaluate the forms of Cd, Cu, Ni, Pb and Zn in seven sewage sludges. There wasExpand
Speciation and removal of zinc from composted municipal solid wastes.
Composting of the organic fraction of municipal solid waste containing 50,000 mg/kg of cellucotton and 7980 mg/ kg of zinc carried out under laboratory conditions and it was found that 65% of zinc occurs in the organically bound form. Expand
Removal of heavy metals from sewage sludge by extraction with organic acids.
Waste water treatment in activated sludge plants results in the production of large amounts of surplus sludge. After composting the sludge can be reused as fertiliser and soil conditioner inExpand
Toxic metals in sewage sludge-amended soils: has promotion of beneficial use discounted the risks?
Abstract Land application of contaminated waste products has been defended as beneficial use by some scientists and regulators, based on the premise that the behavior of any toxins accumulated inExpand
Sequential extraction procedure for the speciation of particulate trace metals
An analytical procedure involving sequential chemicai extractions has been developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions:Expand
