متن کاملInfluence of Dissolved Organic Matter on the Solubility of Heavy Metals in Sewage-Sludge-Amended Soils
Sewage-sludge-amended soils generally contain elevated levels of organic matter and heavy metals compared to control soils. Because organic matter is known to complex with heavy metals, the solubility behavior of the organic matter in such soils may exert a significant influence on the solubility of the metals. Little is known about such a process. Using batch experiments in which the solubilit...

متن کاملCo-transport of dissolved organic matter and heavy metals in soils induced by excessive phosphorus applications.
To evaluate the effects of long-term applications of phosphorus fertilizers on mobility of dissolved organic matter (DOM) and heavy metals in agricultural soils, a sandy soil and a loamy soil were spiked with ammonium phosphate at application rates of 0, 25, 50, 100, 250, and 500 mg P per kilogram of soil. A series of 15-cm long soil columns were constructed by packing incubated soils of varyin...
متن کاملSorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil.
Mobility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from soils to surface waters. To study the sorption and mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM to samples from Ap, EB, and Bt horizons from a Danish agricultural Humic Hapludult was investigated and a kinetic model applicable in field-scal...
