The leaching tests of heavy metals in industrial sewage sludge were carried out under different pH of extractant by the solid waste extraction procedure for leaching toxicity (GB5086.2-1997) of China on the base of the contents and fractions of Zn, Cu, Pb, Cr, Mn and Ni elements. The results showed that the sludge was with higher levels of Mn and Zn, followed by Cu and Ni, while the higher toxicity of Pb and Cr was lower. The fractions of different elements in the sewage sludge had very different forms. The potential migration and biological toxicity were a concern for the active forms of Zn, Mn, Ni, Cr because their active proportions were more than 50%. The pH of extraction solutions had an important impact on the leaching of heavy metals in sewage sludge. The largest concentrations of Zn, Mn, Ni, Cu were appeared when the pH of extractant was about 7, but that of Fe had a greater fluctuation at the same pH. The concentrations of heavy metals had very different at different pH values, which may be related with the process of adsorption/desorption, complexation/dissociation, the dissolution/precipitation/co-precipitation and other chemical reactions in the extractant process.

Biochar can be produced from many various feedstock including biomass residues such as straw, branches, sawdust and other agricultural and forestry waste. One of the alternatives is to obtain biochar from industrial sewage sludge, however, the use of such a product could be limited due to high quantities of heavy metals in the biochar as a product. Total concentration of heavy metals provides only limited information on the behavior of heavy metals, therefore, batch leaching and up-flow percolation leaching tests were applied to study the leaching of heavy metals (Cd, Pb, Cr, Ni, Zn, Cu) from (bio)char produced from two types of sewage sludge: from paper mill and leather industries. Bioanglis gali būti gaminama iš daugelio įvairių pramonės žaliavų, įskaitant biomasės liekanas, pavyzdžiui, šiaudus, šakas, pjuvenas ir kitas žemės ūkio ir miškininkystės atliekas. Viena iš alternatyvų – bioanglį gaminti iš pramonės nuotekų dumblo, tačiau tokį produktą galima naudoti ribotai dėl jame esančio didelio sunkiųjų metalų kiekio. Iš bendrosios sunkiųjų metalų koncentracijos tyrimų galima tik ribotai spręsti apie sunkiųjų metalų pasiskirstymą, todėl buvo taikomi du tyrimai: tyrimas, perkoliuojant atliekas vienakrypte srove, bei dvipakopis partijos (tyrinio) tyrimas siekiant išanalizuoti sunkiųjų metalų (Cd, Pb, Cr, Ni, Zn, Cu) išplovimą iš bioanglies, pagamintos iš dviejų rūšių nuotekų dumblo: popieriaus gamybos ir odos pramonės.

Background: Sewage treatment leads to the production of large amount of sludge, containing organic matter and nutrients and considering requirements for recycling could be used as fertilizer. The sludge may also contain various pollutants that pose serious harm to human health and the environment. This study aimed at characterizing the industrial sewage sludge and evaluating its capability as fertilizer with no or a minor pretreatment. Methods: The sludge’s organic matter and nutrient contents, heavy metals, organic and microbial contaminants were determined and compared to literature data and international guidelines. Results: The organic matter, nutrients, phosphorous, and exchangeable potassium contents of the sludge samples were significantly high as follows: 33.6 ± 2.85 %, 6.29 ± 0.16 %, 1.41± 0.01 % and 1.236 g/kg, respectively. The concentration of heavy metals was 94.3 ± 59.5 mg/kg. The concentration of heavy metals, organic contaminants, such as PCBs, BTEX, and PAHs, and microbial contents (coliforms & E. coli) were lower than those reported by other studies. Toluene concentration was high. Conclusions: All characteristics of the sludge samples, except for the toluene and microbial contaminations, were acceptable for its use as land fertilizer. Both toluene and microbial contaminants can be removed, using thermal conditioning as a pretreatment.

A field experiment was conducted to demonstrate the beneficial and negative aspects of sewage sludge application on wheat and to determine the way of heavy metals in the sludge-soil-plant system. Two types of sewage sludge (urban and industrial) were applied at different rates (5, 25, 50 and 100 t dry matter (DM) per ha). Results showed that growth and yield have been improved by sewage sludge use. However, sewage sludge applications modified the content of heavy metals in plant tissues especially for industrial sewage sludge and high rates where significant accumulations including Co, Cr and Pb, were detected mainly in the roots. This has been coupled by an alteration of the root cellular ultra-structure and the presence of heavy metal deposition as electron-dense granules and crystals.

The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and Zn applied to soils in urban anaerobically stabilized sewage sludge. The soils were Lithic Haplumbrept (Lh), Calcixerollic Xerochrept (Cx1 and Cx2) and Paralithic Xerorthent (Px). Sunflower plants (Helianthus annuus L) were grown in the soils following amendment with the sludge. The addition of sewage sludge markedly increased the average dry weight of the plants in the soils that had lower yields without sludge addition (Lh, Cx2, and Px). The acid pH of the Lh soil favoured the bioavailability of Zn from sewage sludge. The bioavailability of Cu was greater in the alkaline soils than in the acidic soil (Lh), which can be attributed to the high organic matter content of the Lh soil which complexes Cu and impairs its uptake by the plants. The concentration of metals in the plants increased with the sewage sludge dose. The effect of the soil type on the metal concentration in plants was greater that the effect of the dose. Key words: Soils, sewage sludge, heavy metals, bioavailability, sunflower
