Heavy Metals Behavior in Soil/Plant System after Sewage Sludge Application

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

The production of sewage sludge has been sharply increasing by municipal sludge treatment plants in China. Sewage sludge is a difficult waste to manage not only due to the high quantities produced but also due to its high concentration of heavy metals and pathogens. The pyrolytic conversion of sewage sludge to biochar and then applied to the land is a sustainable management potion. Therefore, t...
