“…The increased concentration of both Zn and Cu and also DOC in the recently amended versus previously amended soils is consistent with previous results, which indicated that leachate concentrations of DOC (Giusquiani et al, 1992), metals (Welch and Lund, 1987; Sawhney et al, 1994), or both DOC and metals (Dudley et al, 1986; Lamy et al, 1993) are the greatest immediately after biosolids addition, and both decrease as leaching progresses.…”

Solution Chemistry Influence on Metal Mobility in Biosolids‐Amended Soils

Many studies have implicated dissolved organic carbon (DOC) as an important contributor to the elevated mobility of trace metals in soils amended with biosolids. Few of these studies, however, have quantified both DOC and metal concentrations. We completed laboratory leaching column studies on a dryland Platner loam (fine, smectitic, mesic Aridic Paleustoll) and an irrigated Osgood sand (loamy, mixed, mesic Arenic Ustollic Haplargid), both with a history of biosolids application. The soils were neutral to slightly alkaline in pH prior to amendment. We performed an additional application of biosolids to one set of columns in the laboratory at a rate of 28 Mg ha(-1) to investigate the effect of time following application on metal mobility. The effect of electrolyte concentration was studied by using both distilled water and simulated irrigation water. Biosolids application increased both DOC and Cu in the column effluents resulting in a positive correlation between Cu and DOC across application treatments for both soils. Both Cu and Pb were mobilized under conditions of low electrical conductivity (EC). This may be the result of the release of a strong metal-binding component of DOC under these conditions. Conversely, Zn mobility was positively correlated with EC, suggesting that either cation exchange or the formation of inorganic complexes influences Zn mobility. Anodic stripping voltammetry measurements indicated that only a small percentage of the total dissolved metals existed as free ions or inorganic complexes; the remainder appears to be complexed to DOC.

“…A slight increase in the concentration of a strongly Cu‐binding DOC component could be masked by an overall decrease in the total DOC concentration. The existence of multiple components with a range of metal binding affinities has been illustrated for DOC extracted from biosolids (Dudley et al, 1986, 1987).…”

“…Metals such as copper, iron, manganese and zinc present in these categories differ in their remobilization behaviors under fluctuating environmental conditions (14) and may accumulate in soils in varying percentages as water-soluble, exchangeable, associated with carbonate, Fe-Mn oxides, organic and residual forms (15). The rapid decomposition of organic matter which occurs after the application of composts to soil, increases the proportion of available metals as a result of mineralization of organically bound metals (18).

Amending soils with compost may lead to accumulation of metals and their fractions at various concentrations in the soil profile. The objectives of this study were to determine 1) the accumulation of Cu, Fe, Mn, and Zn with depth and 2) the distribution of water soluble, exchangeable, carbonate, Fe-Mn oxides, organic and residual forms of each metal in soils amended with MSW compost, co-compost, biosolids compost and inorganic fertilizer (as control). Total concentrations of Cu, Fe, Mn and Zn were concentrated in the 0-22 cm soil layer and scant in the rock layer. These metals were in the decreasing order of Fe >> Mn > Zn > or = Cu. Copper, Fe, and Zn were predominantly in the residual form followed by fractions associated with Fe-Mn oxides, carbonate, organic, exchangeable and water soluble in all treatments except MSW compost amended soil where the organic fraction was higher than the carbonate fraction. In fertilizer, co-compost and biosolids compost treated soils Mn concentrated mainly in the Fe-Mn oxides form followed by residual, carbonate, and organic forms whereas, in MSW compost treated soil the same pattern occurred except that Mn organic fraction was higher than that in the carbonate form. The MSW compost has a greater potential to be used as a soil amendment to supply plants with Cu, Mn and Zn than other treatments in calcareous soils of south Florida.

Simard, R. R., Beauchemin, S. and Laverdière, M. R. 1999. Limed sewage sludge effects on nutrient status and metal fractions in acidic soils. Can. J. Soil Sci. 79: 173-182. The potential impacts of limed sludge on nutrient and heavy metal bioavailability must be studied for their safe use on acidic soils. The objective of this study was to assess the impact of limed sludges on six acidic soils from eastern Canada. CaCO 3 and raw sewage sludges (RSS) stabilized with either CaO (CaO + S) or cement kiln dust (CKD + S) were added to soils in amount necessary to reach pH 6.5 and the mixtures were then incubated for 64 d. CaO + S treatments were the most efficient to neutralize soil acidity. After 10 d of incubation, the Sr-citrate extractable P was significantly increased by the CaO + S treatment in low P sorption soils. The extractable K, Zn and Cu contents were also slightly increased by CaO + S compared to CaCO 3 whereas CKD + S resulted in an excessive soil exchangeable K content. After 64 d, labile Al content was decreased by all liming amendments. RSS and CaO + S tended to increase labile Cu and Mn contents. The RSS increased NaOH-extractable Cu but the treatments had no significant effects on the labile and stable forms of heavy metals. A combination of CaO+CKD to stabilize sewage sludge would be more suitable to provide appropriate levels of P and K without resulting in large increases in extractable heavy metal contents. Bien que les BSB aient accru le Cu extrait au NaOH, les amendements calcaires n'ont pas eu d'effet significatif sur les formes labiles et stables des métaux lourds. Une combinaison de CaO + PS serait plus adéquate pour stabiliser les boues puisque des niveaux appropriés de P et K seraient apportés sans pour autant augmenter largement les teneurs en métaux lourds solubles.
