One of the possibilities of removing heavy metals (HMs) from soil is the use of phytoremediation techniques supported with biosolids, which also allow for their disposal. Therefore, the objective of the research was the determination of the sewage sludge suitability after its application to urban soil in order to increase the phytoremediation efficiency of contaminated soil. A field experiment was established on lawns in Białystok (Poland) in two locations with different traffic. The research plots were fertilized with sludge in doses of 14.5 t DM/ha and 29 t DM/ha. A mixture of lawn grasses was sown on the prepared plots. During two years of experiment soil/plant samples were collected, and pH, organic matter, dehydrogenase and catalase activity (soil), the total content of Cd, Cr, Cu, Mo, Ni, Pb, Zn, and Hg (soil/plant), and their fractions (soil) were determined. The HMs in soil were present mainly in residual and reducible fractions. Zn had the highest share in acid-soluble fractions (17–45%). The efficiency of urban soil phytoremediation was determined by the calculation of bioconcentration (BCF) and translocation (TF) factors. The highest values for BCF and TF were obtained for Mo (1.97 and 1.99, respectively). In the presented study, sludge amendment caused an immobilization of heavy metals.

This study was aimed to investigate  the ability of Jerusalem artichokes (Helianthus tuberous L.) to absorb heavy metals in an oil-contaminated ecosystem.  The research was carried out in a  territory of the oil and gas pipeline  at the village of  Bytkiv of Nadvirna district.  Jerusalem artichokes were used for this study and planted on an area of 25 m2.  The area of the experimental field in the village of  Maidan of Tysmenytsia district (control option № 1).  A total of eight treatments of the experiment with different rates of sewage sludge.  It is established that the concentration of heavy metals in oil-contaminated soil and Jerusalem artichoke plants increases with increasing the amount of fertilizers in the soil. The maximum content of metals in the tested soils, green mass and Jerusalem artichoke roots was observed  mainly in the variant of sewage sludge application at the rate of 40 t/ha and fertilizer N10P14K58.The green mass and roots of Jerusalem artichoke exhibited the highest content  of heavy metals absorption the transition coefficients of metals in the system "roots - green mass" increase in the following : Pb → Co → Ni → Cd.  The coefficients of biological absorption of metals by Jerusalem artichoke increase in a number of elements: Co  → Ni → Ld → Ca. Where as  The coefficients of biological accumulation of heavy metals with Jerusalem artichoke increase in a number of elements following series : L → Co → Ni → Ca. It is recommended to use Jerusalem artichoke as a phytoremediator of man-made areas.

The mineralisation of organic matter (OM) when sewage sludge was used as amendment in 70 contrasting agricultural soils from Spain was analysed. Soils received a single dose of sewage sludge (equivalent to 50t dry weight ha<sup>-1</sup>) and the O<sub>2</sub> consumption was continuously monitored for 30 days using a multiple sensor respirometer in a laboratory experiment. The cumulative O<sub>2</sub> consumption and rates after 8 and 30 days of incubation (O<sub>2 cum</sub> 8d, 30d and O<sub>2 rate</sub> 8d, 30d), the respiratory quotient (RQ), the maximum O<sub>2</sub> rates over the incubation period (O<sub>2 max</sub>) and time from the beginning of the incubation when O<sub>2 max</sub> occurred (T<sub>max</sub>), were determined in both amended and non-amended soils. Sewage sludge application resulted in increased values for O<sub>2 max</sub>, O<sub>2 rate</sub> 8d, and O<sub>2 cum</sub> 30d. Differences were minor for T<sub>max</sub>, RQ 8d and O<sub>2 rate</sub> 30d. A considerable amount of the initial OM applied was mineralised during the first 8 days. Organic matter decomposition (as expressed by O<sub>2 cum</sub> 30d) was favoured in soils with high values of pH, carbonates, soil organic carbon and low values of amorphous Mn. Soils with these characteristics may potentially lose soil C after sewage sludge application.

When sewage sludge is used as a soil conditioner, heavy metal contamination can limit its application rates. The potential hazard of heavy metals is, however, dependent on the physico-chemical forms of the metals in the sludge and soil. Bauxite refining residue (red mud) has been used to reduce the mobility and availability of heavy metals in municipal solid waste compost. In the present research a sequential step extraction was employed to investigate metal speciation (into exchangeable, bound to carbonate, to Mn & Fe oxides, to organic matter and in residue phase) and the effect of red mud on metal speciation in sewage sludge for Cd, Cr, Cu, Ni, Pb and Zn. The effect of red mud addition on metal distribution in sewage sludge compost was significant. Red mud addition can effectively reduce the metal mobility and the potential hazard of releasing metals from sludge due to the further breakdown of organic matter. Drying of sludge makes heavy metals more available. Red mud addition will be desirable in such a case. Plant available metals (determined by DTPA extraction) are, however, not as effectively reduced except for Pb and Zn.

Sludge Application

The application of sewage sludge on agricultural soils is a promising technical solution. Pot experiments were performed to study the effect of sewage sludge application on growth, physiology and accumulation of heavy metals in three kinds of wheat. The experimental results showed soil pH decreased significantly with the increase of the application of sewage sludge. The contents of Cu, Zn and Pb in the mixed soil did not exceed the Environmental quality standards for soils in China for Grade II (GB-1518-1995).Wheat obtained good growth activities after the application of sewage sludge, however, high land application of sewage sludge (the ratio of sludge in the mixed soil of dry weight was 20% and 25%) inhibited seed emergence and root length. The content of total chlorophyll in wheat increased with the increase of sewage sludge application first and reached a maximum, and then decreased with a further increase of sewage sludge. Compared with the control, the a/b value in chlorophyll showed trace change. The content of proline in wheat increased with the increase of sewage sludge in low doses of sewage sludge (5%, 10% and 15%), while there was no significant increase in the content in high land application of sewage sludge. The physiological metabolism of wheat will exhibit abnormality as the stress of pollutants from sludge exceeded the tolerance of wheat. The content of three kinds of heavy metals in wheat grain increased obviously with sludge application increasing, indicating an increasing trend, and had the phenomenon of exceeded the safety qualification of non-environmental pollution food in china at high doses of sewage sludge. Taking account of the effects of sewage sludge application on growth,physiology and accumulation of heavy metals in wheat, the doses of sludge in the mixed soil of dry weight should be lower than 15%.
