“…The opposite effect, i.e., increased concentrations of metals in soil solutions observed after CO-treatment, was associated with relatively high content of DOC, (2,730 mg kg -1 ) in the compost used in the experiment. Increased solubility of Cu, Zn, and Pb caused mainly by their complexing with biosolids-derived DOC, has also been reported by several other authors [24][25].…”

“…Other authors have also found higher Ni mobility as compared to Cu and Zn in neutral soils after the addition of several organic residues (Kaschl et al, 2002;Ashworth and Alloway, 2004;Toribio and Romanya, 2006).…”

“…The Ni concentrations in the leachates collected from both MSS and EMSS treatments during the first 10 d exceeded the WHO limits of drinking-water-quality guidance. Kaschl et al (2002) studied the influence of soluble OM from municipal solid-waste compost on trace-metal leaching in calcareous soils. They found that the majority of water-soluble trace-metal species from compost accumulated in the topsoil rather than washing out, with the exception of Ni.…”

Leaching column experiments were conducted to determine the degree of mobility of heavy metals (HMs) and nutrients after the addition of municipal solid sewage sludge (MSS) in a sandy-loam soil. Treatments were (1) soil application of low metal content MSS, (2) soil application of metal-enriched municipal solid sewage sludge (EMSS), and (3) control. The MSS application represented a dose of 200 Mg dry weight (dw) ha -1 . Soil columns were incubated at room temperature for 15 d and were irrigated daily with distilled water to make a total of 557 mm. Leachates were collected and analyzed for HMs and nutrients. The Ni and Pb added to soil via MSS and EMSS were found to be leached through the 20 cm columns of calcareous sandy soil although Ni and Pb concentrations in the percolate were small relative to the total amounts of metals applied. Losses of K + from the EMSS, MSS, and control were 92.5, 82.0, and 52.5 kg ha -1 , respectively. Losses of Mg 2+ were in the range from 104.4 (control treatment) to 295.2 kg ha -1 (EMSS), while the loss of Ca 2+ was in the range from 265.0 (control treatment) to 568.2 kg ha -1 (EMSS). The results showed that the amounts of P leached from EMSS (3.02 kg ha -1 ) and MSS (2.97 kg -1 ha -1 ) were significantly larger than those from the control treatment (1.54 kg ha -1 ). The geochemical code Visual MINTEQ was used to calculate saturation indices. Leaching of P in different treatments was controlled by rate-limited dissolution of hydroxyapatite, b-tri-Ca phosphate, and octa-Ca phosphate. The results indicate that application of MSS to a sandy soil, at the loading rate used in this study, may pose a risk in terms of groundwater contamination with Ni, Pb, and the studied nutrients.

“…Metal mobility can be affected also by the various types of organic matters (insoluble, dissolved and colloidal) (Tyler and McBride 1982;Kaschl et al 2002c). The soluble metal-organic matter complexes increase the bioavailability and mobility of metals in the soil, while the insoluble organic complexes effectively remove metals from the solution (Kaschl et al 2002a).…”

The problem of soil preservation and restoration has became more intense due to continued deterioration of the ecological systems of the world. This problem is especially important for Azerbaijan, where environmental pollution by heavy metals and oil products is increasing. Though the nature of toxicity of these two factors is different, they both affect plant productivity, including agricultural crops and human health. This review is devoted to the analysis of modern conceptions on fundamental physiological mechanisms of plant resistance to toxic levels of heavy metals and organic pollutants in soils, also of their uptake and translocation in plants. Different aspects of the nature of toxicity of metals and petroleum hydrocarbons and genetic basis of plant resistance to them, hyperaccumulation mechanisms of heavy metals by some plant species and approaches to phytoremediation of both inorganic and organic pollutants are discussed.
