“…This can be explained by the low heavy metal concentrations in the sludge and the slightly high pH than 7. Peles et al (1998) found that heavy metal concentrations (Cu, Zn, Cd and Pb) were significantly lower in plants collected from soils with high pH. Although the sewage sludge used in this study is suitable for agricultural use, but if it is applied in high amounts to soil over long periods, Zn and other HMs can reach a dangerous level for public health.…”

We studied the mobility and transport of heavy metals such as Cu, Zn, As, Cd, Cr, Ni, and Pb, from soil and soil amended with sewage sludge to sorghum plants. The total and ethylenediaminetetraacetic acid (EDTA) extractable heavy metals in agricultural soil and untreated domestic sewage sludge (DWS) samples were determined. The correlation between the total and extractable metals in soil and sewage sludge was investigated. The total and extractable heavy metals in soil, sewage sludge and sorghum grain were analysed by flame and electro thermal atomic absorption spectrometer (FAAS/ETAAS), after digestion in microwave oven. Statistically good correlations were obtained between the total contents of all heavy metals and their respective extractable fractions in soil and domestic wastewater sludge. Transfer factors of all heavy metals from domestic sewage sludge to sorghum grains were determined.

“…Liming is a common practice in agriculture to maintain optimal soil pH and has also been used to reduce the solubility of HMs (Fang and Wong 1999). Peles et al (1998) found that Zn, Cu, Cd and Pb concentrations in various field plant species were significantly lower in plants collected from limed compared to unlimed sludge-treated plots.…”

The recycling of sewage sludge on agriculture land represents an alternative, advantageous, disposal of this waste material. The aim of the present study was to evaluate the feasibility of using industrial sewage sludge, produced in Pakistan, as a fertiliser. Agricultural soil amended with 25% (w/w) sewage sludge with or without lime treatment was used for growing a variety of sorghum (PARC-SS-1). The mobility of the heavy metals (HMs) (Cd, Cu, Cr, Ni, Pb and Zn) and metalloid (As) in the untreated industrial waste water sewage sludge (UIWS) samples were assessed by applying a modified BCR (Community Bureau of Reference) sequential extraction procedure. The single extraction procedure comprised of the application of mild extractant (CaCl 2 ) and water for the estimation of the proportion of easily soluble metal fractions. The precision and accuracy of BCR was evaluated by using a certified reference material of soil amended with sewage sludge BCR 483. The plant available metal contents, as extracted by the deionised water and 0.01 M CaCl 2 solution and exchangeable fraction of BCR sequential, decreased with lime application in the range of 10-44% for As, Cr, Ni, Pb and Zn, except in the cases of Cd and Cu, where their mobility was increased by 10% and 24%, respectively. Sludge amendment enhanced the dry weight yield of sorghum and the increase was more obvious after liming up to 25%. The uptake of HMs were lower in test samples (3.2-21.8%), except for Cu and Cd, which was higher (4%), while they were below the permissible limit of these metals. The present experiment demonstrates that liming was important in factors facilitating the growth of sorghum in sludge-amended soil.

“…In old-field communities where sludge has been discarded by municipalities, S. faberi has been shown to readily uptake and sequester Cd, Cu, Pb, and Zn in roots, shoots, leaves and seeds (Levine et al 1989;Peles et al 1998). When grown in mixed communities with grass species that are used for prairie restoration, low densities of S. faberi have been shown to be beneficial as a nurse species (Endress et al 1999).…”

known as giant foxtail, is an annual graminaceous weed that is native to eastern China, has colonized eastern North America and is expanding its range westward. This species is primarily self-pollinated and the only mechanism of reproduction is by seed. Adult plants may reach 2 m in height and produce over 2000 seeds per panicle. Seeds may possess non-deep physiological dormancy when freshly produced, and can form small persistent seed banks. If not controlled, S. faberi populations can cause severe yield reductions in corn and soybean crops. Several herbicides are available to provide chemical control; however, resistance to some modes of action, (ALS, ACCase, and Photosystem II) have been identified in Canada and the United States. Leaves and seeds of this species provide a food source to several species of mammals, birds, and insects.
