“…The soluble organic fraction therefore contains a substantial proportion of relatively recalcitrant, phenolic humic polymers and other relatively stable material (e.g. microbial cell wall components; Zhou et al 2000). The higher metabolic quotient in biosolids than poultry manure treatments suggests this since an increase in metabolic quotient can be interpreted as a response by soil microflora to adverse conditions (either environmental stress or disturbance (Wardle and Ghani 1995).…”

“…The interpretations of the FT-IR spectra were based on Zhou et al (2000). Additionally, cyclic voltammograms (CVs) of the freeze-dried DOM [dissolved in dimethyl sulfoxide (DMSO)] were obtained using a potentiostat (CHI605C, Shanghai Chenhua, China) and a three-electrode cell (BAS; 1.0 mmol/L NaClO 4 electrolyte, 3 mm diameter Pt disk working electrode, Pt wire counter electrode, Ag/AgCl reference electrode).…”

“…The freeze-dried DOM was fractionated using macroreticular exchange resin using the method described by Zhou et al (2000), which leads to separation and quantification of the hydrophobic and hydrophilic fractions. The molecular size distribution of the DOM was determined using dialysis bags (Spectra/Por 7, Spectrum Industries, California, USA) with nominal molecular weight cutoffs of 1,000 and 25,000 Daltons according to the method described by .…”

Purpose Land utilization of sewage sludge and sludge compost is a common practice in many countries. Soils amended with sewage sludge and sludge compost display different physicochemical properties, especially in terms of dissolved organic matter (DOM) composition that affects the electron-donating capacity (EDC) of DOM in soils. The aim of this paper was to compare the EDC of DOM derived from sewage sludge and sludge compost for enhancing Fe(III) bioreduction. It is expected that this research could be helpful for further understanding of soil remediation in the future. Materials and methods Sludge and compost DOM were extracted from sewage sludge and sludge compost, respectively. Fractionation, CHNO/S analysis, Fourier-transform infrared and ultraviolet-visible spectroscopy, and cyclic voltammetry were then used to determine the degree of aromaticity and humification in the samples. To determine if their EDC was altered during composting, samples were reduced by the humic-reducing bacterium, Shewanella cinica D14 T , after which their EDC values were determined. The initial and potential EDC values of the samples were measured using FeCl 3 /Fe(citrate) as an electron acceptor. The insoluble Fe(III) oxide reduction by strain D14 T was mediated by DOM.

“…The chemistry of sewage sludge DOM has been investigated in a number of studies (e.g. Baham and Sposito 1983;Zhou et al 2000;Réveillé et al 2003) and has been shown to increase metal mobilisation, especially at high pH (Ashworth and Alloway 2007). However, as both the concentration of DOC and pH decreased after the first leaching, dissolved organic matter originating from the sludge played a minor role in mobilising metals in the SStreated columns.…”

A 20-month column experiment investigated leaching of Al, Cu, Mn, Ni, Zn, Cd and Pb during sulphide oxidation in mine tailings with and without sewage sludge (SS) amendment. Leachate pH decreased gradually in all columns during the experiment, irrespective of treatment, due to sulphide oxidation. As the degree of sulphide oxidation, and thus the pH trajectory, differed between replicates (n=3), running data for each column used are reported separately and the relationships between sulphide oxidation, metal leaching and treatment in each column compared. Mean pH in the columns correlated negatively with total amounts of leached SO 4 2-. In the beginning of the experiment the leachate concentrations of Al, Cu, Zn, Ni and Pb were higher in SS-treated columns due to high initial concentrations of dissolved organic carbon. As leaching proceeded, however, the amounts of Al, Cu, Mn and Ni leached from the columns were closely related to the degree of sulphide oxidation in each column, i.e. to its mean pH. There were no statistically significant differences between treatments regarding the total amounts of metals leached and thus addition of sewage sludge to the tailings appeared to play a minor role for metal leaching patterns. Peak concentrations of Al and Cu in the leachate from untreated tailings and of Zn in the leachate from both untreated and SS-treated tailings at pH 4 exceeded national background values for groundwater.
