15 صفحه اولEffects of metal (Cd, Cu, Ni, Pb or Zn) enrichment of sewage-sludge on soil micro-organisms and their activities
Sewage-sludge may improve soil fertility but there is concern about effects of sludge metals on soil micro-organisms and microbial processes. In a series of laboratory incubations of soil–sludge mixes, effects of varying sludge metal (Cd, Cu, Ni, Pb and Zn) contents on respiration, biomass C and N, and N mineralization were measured. Individual metals were added to a standard sludge in separate...
متن کاملSoil Remediation: Metal Leaching from Contaminated Soil through the Modified BCR Sequential Extraction Procedure
Sequential extraction is a useful method of identifying how toxic trace metals bind to soil particles and the strength of these bonds. This is very essential knowledge to reach an efficient soil washing when dealing with remediation of metal-contaminated soil. Sequential extraction uses a succession of extractions on a soil same sample, with extraction liquids expected to promote decreasing mob...
متن کاملFractionation of heavy metals in liquefied chromated copper arsenate 9-treated wood sludge using a modified BCR-sequential extraction procedure.
Chromated copper arsenate (CCA)-treated wood was liquefied with polyethylene glycol/glycerin and sulfuric acid. After liquefaction, most CCA metals (98% As, 92% Cr, and 83% Cu) were removed from liquefied CCA-treated wood by precipitation with calcium hydroxide. The original CCA-treated wood and liquefied CCA-treated wood sludge were fractionated by a modified Community Bureau of Reference (BCR...
متن کاملAssessment of Extractability of Cu , Cr , Ni , Pb and Zn in some Chilean Biosolid - Amended Soils by using BCR Sequential Extraction Procedure
O efeito da aplicação de biossólido na distribuição e extração de Cr, Cu, Ni, Pb e Zn foi avaliado em solos Molisol de uma importante zona destinada à agricultura no Chile central. Massas de 15 e 30 Mg ha de biossólidos foram adicionadas aos solos e os mesmos foram incubados por 60 dias sob condições controladas de umidade e temperatura. Quatro biossólidos domésticos foram obtidos em uma das pl...
